Objective(s):To examine the expressions of CD11a, CD11b, and CD11c integrins in the myocardial tissues of rats with isoproterenol-induced myocardial hypertrophy. This study also provided morphological data to investigate the signal transduction mechanisms of myocardial hypertrophy and reverse it. Materials and Methods: A myocardial hypertrophy model was established by subcutaneously injecting i...

The CD11a/CD18 (leukocyte function-associated antigen 1 [LFA-1]) integrin mediates critical leukocyte adhesive interactions during immune and inflammatory responses. The CD11a promoter directs CD11a/CD18 integrin expression, and its activity in lymphoid cells depends on a functional RUNX1/AML-1-binding site (AML-110) within the MS7 sequence. We now report that MS7 contains a C/EBP-binding site ...

Efalizumab (Raptiva) is a humanized monoclonal antibody specific for CD11a, the alpha-chain component of the lymphocyte function-associated antigen 1. In humans, the rate of efalizumab elimination from serum was related to the level of CD11a cell surface expression. These data suggested a role for the CD11a receptor, itself, in efalizumab clearance. Recently, we conducted a series of in vitro s...

The process of lymphopoiesis begins in the bone marrow (BM) and requires multiple cellular intermediates. For T cell production, lymphoid progenitors exit the BM and home to the thymus where maturation and selection ensue. These processes are dependent on a number of factors, including chemokines and adhesion molecules. Although the β2 integrin CD11a plays an important role in the migration of ...

Summary. Aim. To study the cytokine regulation of immune response in patients with severe acute necrotic pancreatitis (ANP).
 Material and methods. A prospective cohort 22 ANP who were treated clinic during 2014-2020 has been performed. We studied changes blood cells expressing clusters CDIIa+, CD162+, CD95+, CD16+, HLA-DR+ molecules, levels interleukins IL-2, IL-4, IL-6. The efficacy trea...

Small numbers of hematopoietic stem cells (HSCs) generate large numbers of mature effector cells through the successive amplification of transiently proliferating progenitor cells. HSCs and their downstream progenitors have been extensively characterized based on their cell-surface phenotype and functional activities during transplantation assays. These cells dynamically lose and acquire specif...

Aberrant CD11a overexpression in CD4+ T cells induces T cell auto-reactivity, which is an important factor for systemic lupus erythematosus (SLE) pathogenesis. Although many studies have focused on CD11a epigenetic regulation, little is known about histone methylation. JMJD3, as a histone demethylase, is capable of specifically removing the trimethyl group from the H3K27 lysine residue, trigger...

CD18 hypomorph mice expressing reduced levels of the common beta2 integrin chain develop aggravated Lyme carditis, compared to that developed by wild-type (WT) mice, upon infection with the spirochete Borrelia burgdorferi. The enhancement of Lyme carditis in these mice is characterized by increased macrophage infiltration, correlating with augmented expression of the monocyte/macrophage chemoat...
