Cytoplasmic dna sensing
WebFeb 15, 2013 · To immunologists, DNA has always had a dark side. Long before it was shown to be the genetic material, it was known to stimulate immune responses ( 1 ). When DNA is in the wrong place, it is a sign of danger. The danger can be in the form of infection where microbial DNA is sensed, or cellular damage that leaks DNA into the cytoplasm … WebMar 30, 2024 · We first asked whether cytoplasmic sensors of LPS other than caspase-11 could be detected in innate immune cells. Immunoprecipitates of biotin-labeled LPS from immortalized bone marrow-derived macrophage (iBMDM) cell lysates (Figure 1 A) were analyzed by mass cytometry.Caspase-11 was identified among the most abundant LPS …
