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 کاملKLRG+ invariant natural killer T cells are long-lived effectors.
Immunological memory has been regarded as a unique feature of the adaptive immune response mediated in an antigen-specific manner by T and B lymphocytes. However, natural killer (NK) cells and γδT cells, which traditionally are classified as innate immune cells, have been shown in recent studies to have hallmark features of memory cells. Invariant NKT cell (iNKT cell)-mediated antitumor effects...
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-cells expressing natural killer (NK) receptors are altered in multiple sclerosis and responses to alpha-galactosylceramide are impaired.
Multiple sclerosis (MS) is an autoimmune disorder characterised by clinical relapse and remission and pathological demyelination with varying inflammation. Because it is suggested that T-cells expressing natural killer cell receptors (NKR) play important roles in regulating human autoimmune diseases, we have quantified populations of T-cells expressing the NKR CD56, CD161 and CD94 in the periph...
متن کاملIncreased Natural Killer Cells Activity in Schizophrenic Patients
Background: Schizophrenia has been associated with altered immunity. Different studies regarding natural killer cell activity (NKA) in schizophrenic patients have shown inconsistent results. Objectives: To evaluate NK cell activity in schizophrenic patients in comparison with healthy control individuals. Methods: 30 medication-free schizophrenic patients and 41 healthy sex, age and smoking st...
