T-cell development in the thymus is largely controlled by an epigenetic program, involving in both DNA methylation and histone modifications. Previous studies have identified Cxxc1 as a regulator of both cytosine methylation and histone 3 lysine 4 trimethylation (H3K4me3). However, it is unknown whether Cxxc1 plays a role in thymocyte development. Here we show that T-cell development in the thy...
BACKGROUND The expression levels of LPL, ZAP70, TCL1A, CLLU1 and MCL1 have recently been proposed as prognostic factors in chronic lymphocytic leukemia. However, few studies have systematically compared these different RNA-based markers. DESIGN AND METHODS Using real-time quantitative PCR, we measured the mRNA expression levels of these genes in unsorted samples from 252 newly diagnosed chron...
Objective: The aim of this study was to assess the prognostic value of CD49d expression in Turkish chronic lymphocytic leukemia patients. Material and Methods: Data for 118 patients from a single center were evaluated. In all, the study included 73 patients for whom complete clinical follow-up data, and flow cytometry test results for CD5/19, CD23/43, CD38, Zap70, Kappa, and Lambda light chains...
Abstract We previously identified that the adhesion molecule P-selectin glycoprotein ligand-1 (PSGL-1) regulates CD8 +T cell effector functions and promotes exhaustion in responses to chronic viral infection melanoma tumors. In this study, we investigated cellular molecular mechanisms by which intrinsic PSGL-1 signaling differentiation of exhausted T cells (T EX). show localizes with TCR upon c...
The T cell receptor (TCR) is a versatile receptor able to generate different signals that result in distinct T cell responses. The pattern of early signals is determined by the TCR binding kinetics that control the ability of the ligand to coengage TCR and coreceptor. Coengagement of TCR and CD4 results in an agonist signaling pattern with complete tyrosine phosphorylation of TCR subunits, and ...
B-cell chronic lymphocytic leukemia (CLL) is characterized by differential BCR signaling and autoimmune complications. Complement modulates B-cell function via C3d and CD21 cross-linked to the B-cell receptor (BCR). We hypothesized that CD21 contributes to BCR signaling and participates in the autoimmunity associated with CLL. We analyzed CD21 expression on 106 CLL patient samples and matched s...
