Introduction DPP4 inhibitors (gliptins) are commonly used antidiabetic drugs for the treatment of type 2 diabetes. Gliptins also act in a glucose-independent manner and show vasoregenerative effects. We have shown that gliptins can remarkably accelerate vascular healing after vascular injury. However, the underlying mechanisms remain unclear. Here, we examined potential signaling pathways linki...
Background : Hodgkin lymphoma is a type of immune system malignancies, constituting about 30% of all cases of lymphomas. It is divided into four subgroups based on histopathologic findings. Recent reports indicate that SDF1 chemokine plays a major role in the development, survival and metastasis of many cancers, including breast, prostate and pancreas. So far, its expression and especially re...
background: myasthenia gravis (mg) is the most common disorder of neuromuscular junction in which autoantibodies develop against nicotinic acetylcholine receptor for unknown reasons. the association of immunomodulator genes with different autoimmune disease has been studied in recent years. objective: the aim of this study was to investigate correlation between a genetic variation in stromal ce...
Precise SDF1-mediated cell guidance is achieved through ligand clearance and microRNA-mediated decay
During animal development, SDF1 simultaneously guides various cell types to different targets. As many targets are in close proximity to one another, it is unclear how the system avoids mistargeting. Zebrafish trigeminal sensory neurons express the SDF1 receptor Cxcr4b and encounter multiple SDF1 sources during migration, but ignore all but the correct one. We show that miR-430 and Cxcr7b regul...
Genetic interaction between donor and recipient may dictate the impending responses after transplantation. In this study, we evaluated the role of the genetic predispositions of stromal-derived factor-1 (SDF1) [rs1801157 (G>A)] and CXC receptor 4 (CXCR4) [rs2228014 (C>T)] on renal allograft outcomes. A total of 335 pairs of recipients and donors were enrolled. Biopsy-proven acute rejection (BPA...
Genetic polymorphisms in chemokine and chemokine receptor genes influence susceptibility to human immunodeficiency virus type 1 (HIV-1) infection and disease progression, but little is known regarding the association between these allelic variations and the ability of the host to transmit virus. In this study, we show that the maternal heterozygous SDF1 genotype (SDF1 3'A/wt) is associated with...
مقدمه: لنفوم هوچکین یک نوع بدخیمی سلول های سیستم ایمنی است و حدود 30% کل لنفوم ها را تشکیل می دهد. این بیماری براساس یافته های هیستوپاتولوژیک به چهار زیرگروه تقسیم می شود. گزارش های اخیر نشان می دهد که کموکاین sdf1 در رشد، بقا و متاستاز بسیاری از سرطان ها مثل سینه، پروستات و پانکراس نقش اساسی دارند اما تاکنون بیان آن و بویژه پذیرنده های آن یعنی cxcr4 و rdc1 در لنفوم هوچکین بررسی نشده است. لذا د...
Normal B-lymphocyte maturation and proliferation are regulated by chemotactic cytokines (chemokines), and genetic polymorphisms in chemokines and chemokine receptors modify progression of human immunodeficiency virus-1 (HIV-1) infection. Therefore, 746 HIV-1-infected persons were examined for associations of previously described stromal cell-derived factor 1 (SDF-1) chemokine and CCR5 and CCR2 ...
We performed a systematic screen for mutations affecting the trajectory of axons visualized by immunohistochemical staining of Medaka embryos with anti-acetylated tubulin antibody. Among the mutations identified, yanagi (yan) and kazura (kaz) mutations caused specific defects in projection of the posterior lateral line (PLL) nerve. In yan and kaz mutant embryos, the PLL nerve main bundle was mi...
The Genetics of Resistance to Infection by HIV-1 (GRIV) cohort represents 200 nonprogressor/slow-progressor (Slowprog) and 90 fast-progressor (Fastprog) HIV-1-infected patients. Using this unique assembly, we performed genetic studies on three recently discovered polymorphisms of CCR5, CCR2, and SDF1, which have been shown to slow the rate of disease progression. The increased prevalence of mut...
