Stromal cell-Derived Factor 1 (SDF1) is the natural ligand of CXCR4, the coreceptor of HIV-1 X4 viruses. This study investigated the role of the single nucleotide polymorphism (SNP) rs1801157 (NM_000609.5:c.*519G>A) of the SDF1 gene in the natural history of mother-to-child transmission of HIV-1 and disease progression of HIV-1-infected children. The study was conducted in 428 children born to ...
Despite the increasing importance of the pig as a large animal model, little is known about porcine neural precursor cells. To evaluate the markers expressed by these cells, brains were dissected from 60-day fetuses, enzymatically dissociated, and grown in the presence of epidermal growth factor, basic fibroblast growth factor, and platelet-derived growth factor. Porcine neural precursors could...
Breakdown of sphingomyelin as catalyzed by the activity of sphingomyelinases profoundly affects biophysical properties of cellular membranes which is particularly important with regard to compartmentalization of surface receptors and their signaling relay. As it is activated both upon TCR ligation and co-stimulation in a spatiotemporally controlled manner, the neutral sphingomyelinase (NSM) has...
زمینه و هدف: هدف از این مطالعه یافتن الگوی تغییرات دو کموکین sdf-1α و ip-10 در نمونه مدل حیوانی متعاقب ایجاد انفارکتوس تجربی به منظور تعمیم نتایج تحقیقاتی به اقدامات بالینی می باشد. مواد و روش ها: در این مطالعه مداخله ای، 18 قلاده سگ (6 تا 12 ماه) در سه گروه 6 تایی تقسیم شدند. 1: گروه انفارکتوس که پس از توراکوتومی (lad) “left anterior descending coronary artery” بسته شده. 2: گروه شم که جراحی ...
