Killer Cell Immunoglobulin-Like Receptors Influence the Innate and Adaptive Immune Responses
Natural killer (NK) cells are a subset of lymphocytes which play a crucial role in early innate immune response against infection and tumor transformation. Furthermore, they secrete interferon-γ (IFN-γ) and tumor necrosis factor (TNF) prompting adaptive immu-nity. NK cells distinguish the unhealthy cells from the healthy ones through an array of cell-surface receptors. Human NK cells use inhibi...
متن کاملHLA-KIR Interactions and Immunity to Viral Infections
Host genetic factors play a central role in determining the clinical phenotype of human diseases. Association between two polymorphic loci in human genome, human leukocyte antigen (HLA) and killer cell immunoglobulin-like receptors (KIRs), and genetically complex infectious disease, particularly those of viral etiology, have been historically elusive. Hence, defining the influence of genetic di...
متن کاملInnate immunity and adjuvants
Innate immunity was for a long time considered to be non-specific because the major function of this system is to digest pathogens and present antigens to the cells involved in acquired immunity. However, recent studies have shown that innate immunity is not non-specific, but is instead sufficiently specific to discriminate self from pathogens through evolutionarily conserved receptors, designa...
متن کاملRole of miR-146a in Immune System and Autoimmunity
MicroRNAs (miRNAs) are small preserved non-coding RNA molecules that regulate gene expression post-transcriptionally by targeting the 3' UTR of mRNAs for translational repression or degradation. The rising evidence has established the significant role of miRNAs within the regulation of immune system and the prevention of autoimmunity. MiR-146a has obtained an importance as a modulator of differ...
متن کاملγδ T Cells Cross-Link Innate and Adaptive Immunity in Mycobacterium tuberculosis Infection
Protective immunity against mycobacterial infections such as Mycobacterium tuberculosis is mediated by interactions between specific T cells and activated antigen presenting cells. To date, many aspects of mycobacterial immunity have shown that innate cells could be the key elements that substantially may influence the subsequent adaptive host response. During the early phases of infection, inn...
