Diversity of T-cell receptor Gene Rearrangements in South Indian Patients with Common Acute Lymphoblastic Leukemia
Background: Precursor B-Acute Lymphoblastic Leukemia (precursor B-ALL) oc-curs due to the uncontrolled proliferation of B-lymphoid precursors arrested at a par-ticular stage of B-cell development. Precursor-B-ALL is classified mainly into pro-B-ALL, common-ALL and pre-B-ALL. The Common Acute Lymphoblastic Antigen CD10 is the marker for common-ALL. Objective: This study was aimed to examine the ...
متن کاملDiversity and structure of human T cell receptor delta chain genes in peripheral blood gamma/delta-bearing T lymphocytes
We have investigated the diversity and repertoire of human TCR delta chain variable gene segments in the human peripheral blood CD4- CD8- (double-negative) population, using rearrangement and expression studies and sequence analyses. 20 TCR delta DNA clones were derived from the RNA of bulk-cultured double-negative T cells and their nucleotide sequences determined. These clones can be classifie...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولanalysis of t cell receptor vβ diversity in peripheral cd4+ and cd8+ t lymphocytes obtained from patients with chronic severe hepatitis b
conclusions the cd4+ and cd8+ tcr vβ gene families undergo clonal expansion in cshb patients, and cd8+ t cells play a major role in the pathogenesis of cshb. moreover, the conserved motifs and limited use of joining region genes observed in the cshb patients of this cohort indicated that similar antigenic epitopes are recognized. results the number of oligoclonal or monoclonal expansion tcr vβ ...
متن کاملLongitudinal analysis of peripheral blood T cell receptor diversity in patients with systemic lupus erythematosus by next-generation sequencing
INTRODUCTION T cells play an important role in the pathogenesis of systemic lupus erythematosus (SLE). Clonal expansion of T cells correlating with disease activity has been observed in peripheral blood (PB) of SLE subjects. Recently, next-generation sequencing (NGS) of the T cell receptor (TCR) β loci has emerged as a sensitive way to measure the T cell repertoire. In this study, we utilized N...
