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 ...

The current study aimed to investigate the effectiveness of Elephantopus scaber and Sauropus androgynus as anti-inflammatory agents in pregnant mice infected with Escherichia coli. This used seven treatments group (n=3): K- (healthy mice), K+ (pregnant E. coli), P1 coli + 100%), P2 75% S. 25%), P3 50% 50%), P4 25% 75%), P5 100%). Flow cytometry analysis was analyze cell populations expressing C...

To evaluate the associations among immune cells (T-cells, B-cells, Macrophages and NK cells) in human endometrium during mid-luteal phase of menstrual cycle. Endometrial biopsies were obtained from 116 women (7 days after LH surge) natural cycles. The presence CD3-positive (T-cells), CD4-positive (T-helpers), CD8-positive (T-killers), CD14-positive (Macrophages), CD68-positive CD56-positive (NK...

We have reported a new innate-like CD4 T cell population that expresses cell surface makers of effector/memory cells and produce Th1 and Th2 cytokines immediately upon activation. Unlike conventional CD4 T cells that are selected by thymic epithelial cells, these CD4 T cells, named T-CD4 T cells, are selected by MHC class II expressing thymocytes. Previously, we showed that the presence of T-CD...

background: lymphocyte subsets enumeration is considered prominent in the management of primary and acquired immunodeficiency disorders. because of local variations due to race, age, gender, and environmental conditions on lymphocyte subsets, and to improve the accuracy of interpretation of laboratory findings, reference intervals must be determined in every population. objective: to establish ...

At mucosal surfaces, immature resident Dendritic Cells, Langerhans Cells and their subsets are the first cell types to encounter HIV-1 virus. During early stages of infection, dendritic cells sense virus through innate immune mechanisms inducing maturation activating adaptive responses. subverts system by hijacking cells, impairing cellular function promote survival propagation trans-infection ...
