Pyogenic Arthritis, Pyoderma Gangrenosum, and Acne Syndrome (PAPA syndrome) is an autoinflammatory disease caused by aberrant production of the proinflammatory cytokine interleukin-1. Mutations in the gene encoding proline serine threonine phosphatase-interacting protein-1 (PSTPIP1) have been linked to PAPA syndrome. PSTPIP1 is an adaptor protein that interacts with PYRIN, the protein encoded b...
Hemozoin (Hz) is the crystalline detoxification product of hemoglobin in Plasmodium-infected erythrocytes. We previously proposed that Hz can carry plasmodial DNA into a subcellular compartment that is accessible to Toll-like receptor 9 (TLR9), inducing an inflammatory signal. Hz also activates the NLRP3 inflammasome in primed cells. We found that Hz appears to colocalize with DNA in infected e...
Innate sensing of nucleic acids lies at the heart of antiviral immunity. During viral infection, dying cells may also release nucleic acids into the tissue microenvironment. It is unknown what effect such host signals have on the quality or duration of the immune response to viruses. In this study, we uncovered an immune-regulatory pathway that tempers the intensity of the host response to infl...
The mammalian innate immune system is activated by foreign nucleic acids. Detection of double-stranded DNA (dsDNA) in the cytoplasm triggers characteristic antiviral responses and macrophage cell death. Cytoplasmic dsDNA rapidly activated caspase 3 and caspase 1 in bone marrow-derived macrophages. We identified the HIN-200 family member and candidate lupus susceptibility factor, p202, as a dsDN...
In response to pathogen infection and tissue damage, inflammasome sensors such as NLRP3 and AIM2 are activated, which triggers PYRIN domain (PYD)-mediated ASC nucleation, followed by self-perpetuating ASC polymerization, which ultimately culminates in caspase-1 activation, interleukin (IL)-1β and IL-18 processing and release and pyroptosis (Ratsimandresy et al., 2013; Cai et al., 2014). Inflamm...
