Cytokine-induced memory-like natural killer cells.
The mammalian immune response to infection is mediated by 2 broad arms, the innate and adaptive immune systems. Innate immune cells are a first-line defense against pathogens and are thought to respond consistently to infection, regardless of previous exposure, i.e., they do not exhibit memory of prior activation. By contrast, adaptive immune cells display immunologic memory that has 2 basic ch...
متن کاملNatural Killer Dendritic Cells Enhance Immune Responses Elicited by α-Galactosylceramide-Stimulated Natural Killer T Cells
Natural killer dendritic cells (NKDCs) possess potent anti-tumor activity, but the cellular effect of NKDC interactions with other innate immune cells is unclear. In this study, we demonstrate that the interaction of NKDCs and natural killer T (NKT) cells is required for the anti-tumor immune responses that are elicited by α -galactosylceramide ( α -GC) in mice. The rapid and strong expression ...
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...
متن کاملAntitumor Responses of Invariant Natural Killer T Cells
Natural killer T (NKT) cells are innate-like lymphocytes that were first described in the late 1980s. Since their initial description, numerous studies have collectively shed light on their development and effector function. These studies have highlighted the unique requirements for the activation of these lymphocytes and the functional responses that distinguish these cells from other effector...
متن کاملRegulation of immune responses by natural killer T cells.
Natural killer T (NKT) cells, which comprise a minor population of T cells in primary and secondary lymphoid organs, possess phenotypic characteristics of both NK and T cells. NKT cells respond to various external stimuli by an early burst of cytokines, including IL-4 and IFN-gamma. Thus, a key immunoregulatory role has been attributed to them. Autoimmune diseases, especially type I diabetes (T...
