Abstrakt: Elucidating the basis of chronic disease courses and the development of appropriate treatment methods for inflammatory diseases still represent a big challenge for medical science, as the mechanisms driving aberrant immune reactions are mostly still unknown. Of particular interest is the identification of checkpoints that regulate the function and differentiation of proinflammatory cells during the pathogenesis, along with methods for modulation of specific checkpoints as a treatment approach. Innate receptors, such as members of the natural killer group 2 family (NKG2X), natural cytotoxicity receptors (NCR) or Toll-like receptors (TLRs), play an important role in modulating the immune response. NKG2 member D (NKG2D) is a potent activating receptor of the immune system, known as a sentinel for cellular danger signals presented by cells exposed to endoplasmic reticulum (ER) stress, cell death or an inflammatory cytokine milieu. NKG2A/C bind the non-classical HLA class I molecule, sense changes in ligand expression associated with malignant transformation and cellular stress and their main function is to send inhibitory or activating signals to NK cells and subsets of T cells. In this review, we present our latest knowledge on the understanding of the role of innate receptors in the context of chronic inflammation and autoimmunity with special emphasis on danger sensor receptors NKG2D and NKG2A/C.
