Innate or adaptive immunity? The example of natural killer cells.
Natural killer (NK) cells were originally defined as effector lymphocytes of innate immunity endowed with constitutive cytolytic functions. More recently, a more nuanced view of NK cells has emerged. NK cells are now recognized to express a repertoire of activating and inhibitory receptors that is calibrated to ensure self-tolerance while allowing efficacy against assaults such as viral infecti...
متن کاملInvariant 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 کاملBridging Innate and Adaptive Immunity
The Nobel Prize in Physiology or Medicine for 2011 to Jules Hoffmann, Bruce Beutler, and the late Ralph Steinman recognizes accomplishments in understanding and unifying the two strands of immunology, the evolutionarily ancient innate immune response and modern adaptive immunity.
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 کاملTransplantation and innate immunity: the lesson of natural killer cells
Natural killer cells have been demonstrated to play a major role in mediating an anti-leukemia effect in patients given a T-cell depleted allogeneic hematopoietic stem cell transplantation from an HLA-haploidentical family donor. In particular, donor-derived natural killer cells, which are alloreactive (i.e. KIR/HLA mismatched) towards recipient cells, significantly contribute to the eradicatio...
