NKG2D ligands link oncogenic RAS to innate immunity
RAS is constitutively active in multiple types of tumor cells. We have recently demonstrated that H-RASV12 enhances the translation of ligands for the activating immune receptor NKG2D, hence rendering cells more susceptible to natural killer (NK) cell-mediated lysis. This effect depends on MAPK and PI3K signaling, but not on the DNA damage response.
متن کاملNOD1 Activators Link Innate Immunity to Insulin Resistance
OBJECTIVE Insulin resistance associates with chronic inflammation, and participatory elements of the immune system are emerging. We hypothesized that bacterial elements acting on distinct intracellular pattern recognition receptors of the innate immune system, such as bacterial peptidoglycan (PGN) acting on nucleotide oligomerization domain (NOD) proteins, contribute to insulin resistance. RE...
متن کاملDNA Makes RNA Makes Innate Immunity
Microbial DNA in the cytosol induces production of interferon-beta (IFN-beta) and an innate immune response. Chiu et al. (2009) now implicate cytosolic DNA-dependent RNA polymerase III as the DNA sensor linking DNA release by pathogenic bacteria and viruses in the host cell cytosol to IFN-beta production and innate immunity.
متن کاملDNA Deamination Mediates Innate Immunity to Retroviral Infection
CEM15/APOBEC3G is a cellular protein required for resistance to infection by virion infectivity factor (Vif)-deficient human immunodeficiency virus (HIV). Here, using a murine leukemia virus (MLV)-based system, we provide evidence that CEM15/APOBEC3G is a DNA deaminase that is incorporated into virions during viral production and subsequently triggers massive deamination of deoxycytidine to deo...
متن کاملA cytokine-mediated link between innate immunity, inflammation, and cancer.
It has been established that cancer can be promoted and/or exacerbated by inflammation and infections. Indeed, chronic inflammation orchestrates a tumor-supporting microenvironment that is an indispensable participant in the neoplastic process. The mechanisms that link infection, innate immunity, inflammation, and cancer are being unraveled at a fast pace. Important components in this linkage a...
