Abstract Introduction/Objective T-cell large granular lymphocytic leukemia (T-LGL) is a lymphoma with persistently increased lymphocytes in peripheral blood. The majority of T-LGL associated CD8+ T-cells. However, the CD4+ variant uncommonly seen. Methods/Case Report patient 49-year-old female history diabetes mellites and anemia who presented shortness breath, lower extremities edema, fatigue....

Background and Aim: IPB-D2 chickens are selected from IPB-D1 due to their disease-resistance characteristics. One-way evaluate the strength of a chicken’s immune system is by examining number circulating T lymphocytes. This assessment can be conducted using modern analytic method called flow cytometry which relies on monoclonal antibodies detect relative proportions each cell measure quality qu...

An effective immune response requires the expansion and survival of a large number of activated T cells. This study compared the role of protein kinase C (PKC)theta and associated signaling molecules in the survival of activated primary CD4+ vs CD8+ murine T cells. We demonstrate that the absence of PKCtheta resulted in a moderate survival defect in CD4+ T cells and a striking survival defect o...

AIMS Normal human pregnancy is a complex process of many immunoregulatory mechanisms which protect fetus from the activation of the maternal immune system. The aim of the study was to investigate the apoptosis of lymphocytes in peripheral blood of normal pregnant patients and healthy nonpregnant women. METHODS Sixty pregnant women and 17 nonpregnant women were included in the study. Lymphocyt...

Despite several studies examining the contribution of allorecognition pathways to acute and chronic rejection of vascularized murine allografts, little data describing activation of alloreactive T cells by mouse vascular endothelium exist. We have used primary cultures of resting or IFN-gamma-activated C57BL/6 (H-2(b)) vascular endothelial cells as stimulators and CD8(+) T lymphocytes isolated ...

BACKGROUND It is well known that lymphocytes play an important role in rheumatoid arthritis (RA). T cell immunoreceptors with immunoglobulin (Ig) and immunoreceptor tyrosine-based inhibitory motif (TIGIT) have immunosuppressive co-stimulatory molecules that mediate inhibitory effects, but their roles in RA are poorly understood. MATERIAL AND METHODS Were recruited 76 patients with RA and 33 hea...

Background: CD4+ and CD8+ T cells are the main types of lymphocytes in cell-mediated immunity and play a central role in the induction of efficient immune responses against tumors. The frequencies of T cell subtypes in the peripheral blood and tumor tissues, and draining lymph nodes (dLN) can be considered as useful markers for evaluation of the immune system in cancers. Methods: In this study,...

T lymphocytes have been demonstrated to play a role in the development of diabetic proteinuria. However, the alteration of circulating T lymphocytes has not been investigated in a type 2 diabetic cohort. A cross-sectional study was conducted in Peking University Aerospace Center Hospital. 510 participants were type 2 diabetes mellitus, 30-70 years of age. Patients with immune disease, medical c...

This study aims to investigate the changes and significance of the peripheral blood T lymphocytes for patients with Hepatitis B Virus (HBV) related acute-on-chronic liver failure. 50 patients with HBV related acute-on-chronic liver failure (liver failure group), 50 patients with Chronic Hepatitis B (CHB group), and 20 healthy persons taking physical examination in the corresponding period (heal...
