Invariant Natural Killer T Cells
Invariant Natural killer T cell (iNKT cells) are a subset of T cells, which are narrowly defined as a T cell lineage expressing a semi-invariant CD1d-restricted T cell Receptors (TCRs) composed by Vα24-Jα18/Vβ11 in human, and Vα14-Jα18/Vβ8,Vβ7, and Vβ2 in mouse. Unlike conventional T cells which recognize peptides bound to highly polymorphic major histocompatibility complex (MHC) class I and II...
متن کاملComparison of Two Flow Cytometric Methods for Detection of Human Invariant Natural Killer T Cells (iNKT)
Background: Invariant natural killer cells (iNKT) are an important immunoregulatory T cell subset. Currently several flow cytometry-based approaches exist for the identifi-cation of iNKT cells, which rely on using the 6B11 monoclonal antibody or a combina-tion of anti-Vα24 and anti-Vβ11 antibodies. Objective: The aim of this study was to compare the ability of two flow cytometry-based methods f...
متن کاملT Helper Cells Profile and CD4+CD25+Foxp3+Regulatory T Cells in Polycystic Ovary Syndrome
Background: Polycystic ovary syndrome (PCOS) is considered as the most common cause of female infertility that affects 4-10% of women in the reproductive age. Previous studies have shown the role of a balanced immune response in a successful pregnancy and fertility. Objective: To investigate the T helper cells type 1 (Th1) /Th2/Th17/Treg paradigms in peripheral blood of infertile PCOS compared ...
متن کاملRelevance of sexual dimorphism to regulatory T cells: estradiol promotes IFN- production by invariant natural killer T cells
Mechanisms accounting for gender dimorphism during immune responses are still poorly understood. Since invariant natural killer T (iNKT) cells exert important regulatory functions through their capacity to produce both T helper 1 (Th1) and Th2 cytokines, we addressed the question of whether these activities could be modulated by sexual hormones. We found that in vivo challenge with the specific...
