“Loss of ζ-associated protein 70 (Zap70) results in severe immunodeficiency in humans and mice because of the critical role of Zap70 in T-cell receptor (TCR) signalling. Here we describe a novel mouse strain generated by N-ethyl-N-nitrosourea mutagenesis, with the reduced protein stability (rps) mutation in Zap70. The A243V rps mutation resulted in decreased Zap70 protein and a reduced duration of TCR-induced calcium responses, equivalent to that induced by a 50% decrease in catalytically active Zap70. The reduction of signalling through Zap70 was insufficient to substantially perturb thymic differentiation of conventional CD4 and CD8 T cells, although Foxp3+ regulatory T cells demonstrated altered thymic production and peripheral homeostasis. Despite the mild phenotype, the Zap70A243V variant lies just above the functional threshold for TCR signalling competence, as T cells relying on only a single copy of the Zap70rps allele for

TCR signalling demonstrated no intracellular calcium response to TCR click here stimulation. This addition

to the Zap70 allelic series indicates that a rate-limiting threshold for Zap70 protein levels exists at which signalling capacity switches from nearly intact to effectively null. “
“Leishmania are protozoan parasites that infect macrophages and their survival is partially achieved Unoprostone through inhibition of the cellular oxidative burst by parasite lipophosphoglycan (LPG). PKCα is the predominant PKC isoenzyme required for macrophage oxidative burst, yet it is not known if different susceptibility of BALB/c and C57BL/6 mice to Leishmania mexicana could be related to PKCα. We analysed the effect of L. mexicana promastigotes and parasite LPG on expression of PKCα and on its activity in macrophages of both mouse strains. Our data show that expression of the isoenzyme was not altered either by LPG or by L. mexicana promastigotes. Yet LPG exerted opposing effects on PKCα activity of macrophages between both strains: in susceptible BALB/c cells, it inhibited PKCα activity, whereas in the more resistant strain it augmented enzymatic activity 2·8 times. In addition, LPG inhibited oxidative burst only in susceptible BALB/c macrophages and the degree of inhibition correlated with parasite survival. Promastigotes also inhibited PKCα activity and oxidative burst in macrophages of BALB/c mice, whereas in C57BL/6, they enhanced PKCα activity and oxidative burst inhibition was less severe.

BCG-primed T cells to Ag85A and those induced by environmental mycobacteria are predominantly CD4+. We did not measure MVA-specific T-cell responses in our study. We observed higher frequencies of total cytokine+, TNF-α+ and polyfunctional CD4+ T cells in adolescents, compared with children. We showed that CD4+ T-cell count, which is highest in neonates and decreases with age 26, 27, did not account for the observed differences. Rather, when we adjusted for age-specific memory CD4+ T-cell proportions, similar

frequencies were obtained between adolescents and children. This data analysis was subject to the caveat that lymphocyte or CD4+ T-cell counts or memory frequencies from individual adolescents and children studied here were not available. Instead, we classified subjects into different age categories, and adjusted FDA-approved Drug Library in vivo for the corresponding median lymphocyte or CD4 counts reported for Ugandan participants 26, or memory T-cell frequencies reported for American children 27. No published lymphocyte or memory CD4+ T-cell counts were available for South African children. Such data would have been more appropriate since co-variates such as helminth infections,

malaria, genetic and/or socioeconomic status are likely be different between South African and Ugandan or American children. Regardless, our results suggest that differential cell counts and/or relative frequencies of memory T cells should be taken into account when comparing immune responses very from children at different ages. The results also suggest that absolute numbers of Ag-specific T cells after vaccination may be similar at different https://www.selleckchem.com/products/pexidartinib-plx3397.html ages; however, additional studies are required to confirm this. An interesting finding was that the peak response detected with the IFN-γ ELISpot assay was at 7 days post-vaccination, while the peak response detected with the whole blood intracellular cytokine staining assay was at 28 days post-vaccination in adolescents. We did not have whole blood samples at 28 days from children to perform the intracellular

cytokine staining assay. The ELISpot assay detects every IFN-γ-expressing cell present in PBMC, whereas the whole blood intracellular cytokine assay detects cytokine expression in the gated T-cell subsets. The latter analysis showed that CD8+ T cells did not contribute significantly to the Ag85A-specific response, and CD4–CD8– T-cell cytokine expression was not detected (data not shown); therefore, non-T cells, such as NK cells, may have contributed to the IFN-γ production detected by the ELISpot assay. This will require confirmation in future studies. Memory T cells can be classified into two major subsets based on CCR7 and CD45RA expression, so-called central memory cells (CCR7+CD45RA−) and effector memory cells (CCR7−CD45RA−). Central memory T cells have been hypothesized to be an optimal phenotype for long-lived protection after vaccination, even though evidence from vaccine studies is lacking 42, 43.

As previously described [20, 22], T2 cells (1 × 106 cells/ml) were incubated overnight with 50 μm of each peptide in serum-free RPMI 1640 medium supplemented with 3 μg/ml β2-M at 37 °C. Cells were washed twice to remove free peptides, then incubated with brefeldin A (10 μg/ml, Sigma, St Louis, MO, USA) for 1 h, washed, and incubated at 37 °C for 0,

2, 4, 6 h. Cells were then washed twice, stained and analysed by flow cytometry. DC50 was defined as the time required for 50% dissociation of the HLA-A*0201/peptide complex stabilized at t = 0 h. It was calculated from the FI values at the peptide concentration of 50 μm. Induction of peptide-specific CTLs by COX-2-derived peptides from human peripheral blood mononuclear cells (PBMCs).  Epacadostat chemical structure CTLs induction in vitro was performed in accordance with the procedures previously described [23, 24]. Briefly, PBMCs of six HLA-A*02+ healthy donors were first obtained with centrifugation at a Ficoll-Paque density gradient APO866 concentration and then cultured in RPMI 1640 medium supplemented with 10% FBS, 100 units/ml penicillin, and 100 units/ml streptomycin. Then, these cells were stimulated once a week with the synthetic peptides, respectively, at a final concentration of 10 μg/ml. Human recombinant IL-2 was added to the culture media at the concentration of 30 units/ml on day 3 and also 1 day after each stimulation. The cytotoxic assay and enzyme-linked

immunospot (ELISPOT) assay were performed on day 21. Enzyme-linked immunospot (ELISPOT) assay.  ELISPOT assay was performed by using a commercial kit (Dakewe, China). The assay was performed in accordance with the procedures previously described [25, 26]. Briefly, T2 cells incubated with p321 and irrelevant peptide

(50 μg/ml) for 4 h were used as stimulators; effector cells (1 × 105) PLEK2 and stimulator cells (p321-pulsed T2 cells, 1 × 105) were seeded into an anti-human (or anti-mouse) IFN-γ antibody-coated 96-well plate. After incubation at 37 °C for 16 h, cells were removed and plates were processed. The number of spots was determined automatically by using a computer-assisted spot analyzer (Dakewe, China). Generation of CTLs from HLA-A2.1/Kb transgenic mice.  In vivo generation of peptides-specific CTLs was performed in accordance with the procedures previously described [27]. Briefly, each HLA-A2.1/Kb transgenic mouse was injected subcutaneously at the base of the tail with 100 μg peptide emulsified in IFA in the presence of 140 μg of the T helper epitope. Mice were injected three times on days 0, 5 and 10 under the same condition. On day 11, spleen lymphocytes (5×107 cells in 10 ml) were separated and stimulated once by peptide (10 μg) in vitro. At day 6 of the stimulation, the specific cytotoxicity and enzyme-linked immunospot (ELISPOT) assays were performed. Cytotoxicity assay.  Cytotoxic activity was tested based on the measurement of LDH release [28] by using the non-radioactive cytotoxicity assay kit (Promega, Madison, WI, USA) at gradient E:T ratio.

3A–C). However, antigen-specific selleck kinase inhibitor proliferation responses were observed in response to a given protein only with spleen cells of mice immunized with the recombinant DNA vaccine construct expressing that protein (Figs. 4 and 5A,C–E; SI > 5.0), except

for PPE68, which failed to induce proliferation responses in animals immunized with pUMVC6/PPE68 or pUMVC7/PPE68 (Figs. 4B and 5B, respectively). The failure of BCG vaccine in humans has prompted the research to develop alternative vaccines against TB. Among the novel vaccine candidates, plasmid DNA–based TB vaccines have drawn close attention because of their unique features compared to conventional live or subunit vaccines, including induction of strong Th1-based CD4+ responses as well as CTL responses [21]. Therefore, the potency of plasmid DNA expressing a variety of immunogenic M. tuberculosis antigens has been intensively evaluated [22]. Unfortunately, their performance is generally not superior to BCG, especially in large animals. However, the licensure of a DNA vaccine in horses highlights the potential of DNA vaccine technology in the prevention of TB infection [23]. Besides, it is generally believed that novel TB vaccines will

be tested in the context of the widely used BCG and perhaps different kinds of vaccines are needed for the eradication of TB [24, 25]. As a result, enhancement of TB DNA vaccine efficacy has become the active field of current research [26]. In this context, Baldwin et al. have shown that inclusion of Paclitaxel cell line the secretion signal peptide from tissue plasminogen activator (tPA) into a DNA vaccine construct resulted in stronger immune responses to Ag85A, and provided sustained protection upon M. tuberculosis challenge in mice, when compared to the DNA vaccine construct based on the parent plasmid lacking tPA [27]. Furthermore, BCKDHA a plasmid DNA vaccine expressing heat shock protein 65 (HSP65-DNA vaccine) provided improved protective and therapeutic effects in mice when fused with human interleukin-2 [28]. The plasmid vectors used in this

study, i.e. pUMVC6 and pUMVC7, are eukaryotic expression vectors, which have been prepared by University of Michigan Vector Core (UMVC) and provided by Aldevron, USA. Both vectors have CMV promoter at 5′ end of the cloning site. pUMVC6 is characterized by having a secretion signal peptide from human interleukin-2 (hIL2 secretory peptide) as an immuno-stimulatory sequence, whereas pUMVC7 has a signal peptide for targeting peptides to a secretory pathway by fusion to the tPA signal peptide. To our knowledge, these DNA plasmid vectors have not been previously used to determine the expression and immunogenicity of M. tuberculosis-specific genes. Furthermore, this study provided direct comparison of tPA and hIL-2 in determining their immunopotentiating effects in DNA vaccine constructs. We cloned genes encoding five major antigenic proteins of RD1 and RD9 of M.

[36] In a culture-proven case of melioidosis, it is important to rule out soft-tissue click here and visceral abscesses by computed tomography of abdomen and pelvis, irrespective of clinical presentation. Abdominal ultrasound is often recommended for children in order to minimize radiation exposure. All cases of melioidosis, irrespective of clinical severity, should be treated with at least 10–14 days (up to 8 weeks in patients with severe disease such as those with ongoing septic shock, deep-seated or organ abscesses, extensive lung disease, septic arthritis, osteomyelitis, or neurologic melioidosis) of initial intravenous intensive therapy, followed by eradication therapy with high-dose

trimethoprim–sulfamethoxazole (TMP + SMX) for a minimum of 3 months (Table 1).[2,

5, 28] Ceftazidime has been in use as the preferred intravenous agent subsequent to the open-label randomized trial from Thailand published in 1989 that demonstrated a significant 50% reduction in mortality rate of severe melioidosis with ceftazidime (120 mg/kg per day) compared with ‘conventional therapy’ (combination of chloramphenicol 100 mg/kg per day, doxycycline 4 mg/kg per day, TMP + SMX 10 + 50 mg/kg per day).[37] With the theoretical advantage of lower minimal inhibitory concentration and more favourable time-kill profile,[38] imipenem has alternatively been shown to be at least as effective as ceftazidime, with no difference in mortality rates in another open-label selleck chemicals llc randomized trial from Thailand.[39] Moreover, in a retrospective clonidine study from Australia,

the use of another carbapenem, meropenem has been shown to be associated with improved outcomes in patients with severe sepsis associated with melioidosis.[40] With the exception of doxycycline, the doses of antimicrobials need to be adjusted in patients with impaired renal function and in those receiving renal replacement therapy (Table 2).[41-45] Burkholderia pseudomallei is inherently resistance to penicillin, ampicillin, first-generation and second-generation cephalosporins, macrolides, quinolones and most aminoglycosides, thereby limiting therapeutic options. Primary resistance to ceftazidime is extremely uncommon but occasional secondary resistance has been reported from endemic locations, usually after prolonged therapy.[46-50] Resistance to carbapenems has not been reported yet. Hence, the use of these antimicrobials could be continued as empirical or first-line therapy for both primary and recurrent melioidosis infection, at least until antimicrobial susceptibility testing of the organism is available. The rate of resistance to TMP + SMX, as assessed with the use of Etest has been reported to be up to 2.5% for Australian isolates but much higher at up to 13% for Thai isolates, although current studies across the endemic region are reassessing this issue.

pylori (6, 34–37). Although H. pylori is predominantly in the c-form in most environments, the best means of identifying dead, resistant or other c-form bacteria is still controversial and the specific roles of the various forms in transmission

routes is not known (6). Agustíet al. have suggested that PMA qPCR will contribute to the understanding of the role of H. pylori in adverse environmental conditions (29). In this study, we used culturable and virulent s-form H. pylori (verified by scanning electron microscope examination, data not shown). Since the importance of the c-form H. pylori has been recently emphasized, particularly in aquatic environments, further studies on the viability and virulence of Raf inhibitor the c-form should be carried out. In conclusion, Selleckchem Opaganib we suggest that PMA is a useful agent to be used in combination with real-time PCR to detect selectively live H. pylori,

and its optimal concentration is 50 μM. This work was supported by K-water (Korea Water Resources Corporation). “
“Bacillus Calmette–Guerin (BCG) has failed to efficaciously control the worldwide spread of the disease. New vaccine development targets virulence antigens of Mycobacterium tuberculosis that are deleted in Mycobacterium bovis BCG. Immunization with ESAT-6 and CFP10 provides protection against M. tuberculosis in a murine infection model. Further, previous studies have shown that calreticulin increases the cell-mediated immune responses to antigens. Therefore, to test whether calreticulin enhances the immune response against M. tuberculosis antigens, we fused ESAT-6 to calreticulin and constructed a recombinant replication-deficient adenovirus to express the resulting

fusion protein (AdCRT–ESAT-6). The adjuvant effect Florfenicol of calreticulin was assayed by measuring cytokine responses specific to ESAT-6. Recombinant adenovirus expressing the fusion protein produced higher levels of interferon-γ and tumour necrosis factor-α in response to ESAT-6. This immune response was not improved by the addition of CFP-10 to the CRT-ESAT-6 fusion protein (AdCRT–ESAT-6–CFP10). Mice immunized with these recombinant adenoviruses did not decrease the mycobacterial burden after low-dose aerosol infection with M. tuberculosis. We conclude that calreticulin can be used as an adjuvant to enhance the immune response against mycobacterial antigens, but it is not enough to protect against tuberculosis. Tuberculosis (TB) is one of the most prevalent infectious diseases in adults, and there are 8–9 million new cases and 2 million deaths from TB annually [1, 2]. The WHO has estimated that one-third of the world’s population is infected with latent TB and that 5–10% of those infected will develop clinical TB. It is worth mentioning that new experimental data support that latent TB infection is a constant, endogenous reinfection process [3–5].

Tumor microenvironments are disturbed with abnormal growth and remodeling of blood and lymphatic vessels. More effective targeting strategies for delivering anti-angiogenic and cytotoxic agents are being developed through advances in intravital imaging. Blood flow control requires both vasodilation and vasoconstriction

to be coordinated along and among arterioles and feed arteries. Evolving insights into signaling pathways between smooth muscle cells and endothelial cells illuminate how such processes can be affected in vasculopathies. These timely reviews provide a novel reference for advancing research frontiers in microcirculation. “
“The pulmonary circulation is a low-pressure, low-resistance vascular bed with little to no resting tone under normal conditions. Dasatinib price An increase in the [Ca2+]i in PASMCs is an important determinant of contraction, migration, and proliferation. Both Ca2+ influx through plasma membrane Ca2+ channels and Ca2+ release from the SR contribute to a rise in [Ca2+]i. Additionally important in the pulmonary circulation are several kinase-mediated signaling pathways that act to increase the sensitivity of the contractile apparatus to [Ca2+]i. Similarly, cytoskeletal processes resulting in dynamic remodeling of the actin cytoskeleton can further contribute to contractility in the pulmonary circulation. In addition to endocrine, paracrine, and autocrine factors,

alveolar hypoxia is an important stimulus for pulmonary vasoconstriction. However, prolonged hypoxia is a critical pathological stimulus associated with the development of pulmonary hypertension and cor check details pulmonale. In this review, we will discuss recent advances in our understanding of how Ca2+ homeostasis and sensitization regulate PASMC contractility under both physiological and pathophysiological conditions. “

“The cerebral blood supply is delivered by a surface network of pial arteries and arterioles from which arise (parenchymal) arterioles that penetrate into the cortex and terminate in a rich capillary bed. The critical regulation of CBF, locally and globally, requires precise vasomotor regulation of the intracerebral microvasculature. This mafosfamide vascular region is anatomically unique as illustrated by the presence of astrocytic processes that envelope almost the entire basolateral surface of PAs. There are, moreover, notable functional differences between pial arteries and PAs. For example, in pial VSMCs, local calcium release events (“calcium sparks”) through ryanodine receptor (RyR) channels in SR membrane activate large conductance, calcium-sensitive potassium channels to modulate vascular diameter. In contrast, VSMCs in PAs express functional RyR and BK channels, but under physiological conditions, these channels do not oppose pressure-induced vasoconstriction.

5 T cells into Foxp3+ Treg cells in the PLNs accumulating in the pancreatic islets. Furthermore, tolerogenic plasmacytoid DCs (pDCs) characterized by low MHC class II molecule expression and TGF-β production are critical in the PLNs for the recruitment of Treg

cells into the pancreatic islets by inducing CXCR3 expression. PD0325901 clinical trial Accordingly, pDC depletion in α-galactosylceramide-treated proinsulin 2−/− NOD mice abrogates the protection against T1D. These findings reveal that upon repetitive iNKT-cell stimulation, pDCs are critical for the recruitment of Treg cells in the pancreatic islets and the prevention of T1D development. “
“Immunoproteasomes containing the IFN-inducible subunits β1i (LMP2), β2i (MECL-1) and β5i (LMP7) alter proteasomal cleavage preference and optimize the generation of peptide ligands of MHC class I molecules. Here, we report on an unexpected new function of immunoproteasome subunits

for the survival and expansion of CD4+ and CD8+ T cells during viral infection of mice. The effect of immunoproteasome subunit deficiency on T-cell survival upon adoptive transfer was most prominent for the lack of LMP7 followed by MECL-1 and LMP2. The survival of T cells in uninfected mice or the homeostatic expansion after transfer into LBH589 in vitro RAG-2−/− mice was not affected by the lack of the immunosubunits. Lymphocytic choriomeningitis virus (LCMV)-specific CD8+ T cells lacking LMP7 or MECL-1 started to divide after transfer into LCMV-infected mice but experienced a considerable cell loss within 2 days after transfer. We provide strong evidence that the loss of immunoproteasome-deficient T cells after transfer is not a consequence of graft rejection by the host, but instead is based on the requirement for immunoproteasomes for the survival of T cells in LCMV-infected mice. Therefore, the immunoproteasome

may qualify as a potential new target for the suppression of undesired proinflammatory T-cell responses. The proteasome Progesterone core complex, referred to as 20S proteasome, is a cylinder-shaped structure consisting of 28 subunits, arranged in four stacked rings. The two outer rings, each made up of seven α-type subunits (α1–α7) are framing the two inner rings, each composed of seven β-type subunits (β1–β7). The catalytic activity is performed by three β-subunits of each inner ring: β1 (δ), β2 (MC14) and β5 (MB1). In the course of an immune response, the constitutive β-subunits are replaced in newly assembled proteasomes by the IFN-γ- and TNF-α-inducible subunits β1i (LMP2), β5i (LMP7) and β2i (MECL-1) 1, thereby building so-called immunoproteasomes 2. Immunoproteasomes cleave Ag with a different cleavage preference 3, 4, thus optimizing the quantity and quality of the generated peptides for presentation by MHC class I molecules 5–8.

Contrary to other activation signals that we applied, poly(I:C) did not tolerize MoDCs to LPS-induced activation and the pre-treatment with IFN-γ, although it did not activate DCs between day 0 and 2, synergized strongly with a later LPS signal (Fig. 1B, left panel). The inability of early-stage MoDCs that develop in the presence of various activation signals to respond to further TLR ligation is in line with previous data obtained with macrophages or DCs 9 and we HIF-1�� pathway showed here that synergistic activation signals do not rescue the cells from functional exhaustion. In addition, we showed the complete lack of inflammatory cytokine gene expression in LPS-tolerized MoDCs in response to further

stimuli, suggesting a major impairment of the signaling cascade that leads to DC activation. In order to search for molecular mechanisms responsible for DC inactivation by chronic

stimulatory signals we compared the gene expression pattern of MoDCs that developed for 2 days in the presence or absence of LPS using selleck compound the Illumina microarray technology and a TLR-pathway focused PCR array (Fig. 2A and Supporting Information Fig. 2). Interestingly, the majority of TLR pathway-associated genes were unaffected by the presence of LPS measured by both technologies, suggesting no major alteration in the expression of the pathway components required for DC activation (Supporting Information Fig. 2). We observed a significant upregulation of potential DC inhibitory factors in response to 2-day exposure to LPS. These included SOCS2 and SOCS3, known regulators of TLR pathways12, the ITIM-containing receptor LILRB2 implicated in DC exhaustion by CD8+ suppressor T cells 23 and the molecules S100A8 and S100A9 that might inhibit DC differentiation and contribute to the development of myeloid suppressor cells in tumor tissues 24. The expression of CD150 (SLAM) molecules, which potently inhibit the CD40L-induced DC activation 25, was also induced

in the presence of LPS. Other known inhibitory factors, including ATF3, SOCS1, STAT3, TGF-β or IRAK-M, were expressed similarly in LPS-treated or control samples. Increased gene expression of the cytokine IL-10 was detected by PCR array in MoDCs cultured for 2 days in the presence of LPS (2.1- to Cyclin-dependent kinase 3 9.5-fold upregulation by LPS, n=3) and confirmed by ELISA (Fig. 2B). Expression of miR146a and miR155 were upregulated by LPS added at day 2 to MoDCs (Fig. 2C) in line with previous findings 15, 16. However miR146a levels were only minimally elevated and miR155 was not affected in MoDCs cultured for 2 days in the presence of LPS as compared with non-treated cells, suggesting a time-limited functionality of these microRNAs in LPS-activated DCs. In order to better understand which DC modulatory factors might participate in DC exhaustion by persistent activation signals we analyzed the expression kinetics of a wide range of potential inhibitory factors in MoDCs developing in the presence or absence of LPS. As shown by Fig.

In addition, elevated urinary albumin excretion rate, as a marker of systemic microcirculatory dysfunction, predicts both incident stroke [73] and survival after stroke [59]. Recently, an elevated urinary albumin excretion rate has been associated with elevated capillary pressure [50] and impaired microcirculatory autoregulation [54]. This abnormality in autoregulation also predicts adverse left ventricular Akt inhibitor remodeling and left atrial size, both predictors of future stroke and

cardiovascular mortality (Figure 1) [55]. Indeed, this autoregulatory abnormality explains the association between left ventricular hypertrophy and albumin excretion rate, and may represent an etiopathogenic link. It is currently under further investigation. Most cardiovascular disease occurs in the proportionately larger number of individuals with low-to-moderate absolute risk. Clinical intervention decisions are often based on the likelihood GSK126 molecular weight that an individual will have a cardiovascular event over a given period of time; however, these decisions are often made on an incomplete assessment of risk. These epidemiological studies have demonstrated the importance of microcirculatory dysfunction as an early marker of vascular disease, prior to established markers, such as elevated glucose, hypertension or left ventricular hypertrophy being present. Screening for

microvascular dysfunction using a combination of the aforementioned techniques can be advantageous for the early detection of microvascular disease, in aiding diagnosis, in monitoring disease progression, and response to therapy. Most of the techniques discussed herein are used in the exploration of microvascular function in a research setting. Only some of these may be easily translated into clinical practice. Investigating the retinal microvasculature is relatively simple and can be employed on a large scale [68]. As such, it has been translated into Carnitine palmitoyltransferase II clinical practice for those

with diabetes at least. Similarly, urinary albumin excretion rate translates easily into clinical practice as its proxy, albumin:creatinine ratio, can be measured on a single urine specimen. Changes in urinary albumin excretion have been shown to be very useful for estimating risk of future CV events [18,31]. Therefore, this suggests that to reduce the risk for cardiovascular disease, progression of urinary albumin excretion should be prevented and regression thereof regarded as a primary treatment goal [9]. However, there are limited data on the long-term cost-effectiveness of systematic screening for urinary albumin excretion and more importantly, targeting it as a therapeutic outcome in those at high risk either by virtue of their hypertension or their past disease such as stroke, transient ischemic attack or myocardial infarction [4].
