The results suggested that established gender differences in pain perception could likely be traced at least in part to this brain network , and offered new evidence that those gender

The presence of segmented filamentous bacteria , a commensal microbe present in some mice , reprograms AM gene expression , increasing complement expression and phagocytosis , thereby enabling AM to engulf and destroy viral pathogens without inflammatory signaling . The composition of microbiota found in the gut influences how susceptible mice are to respiratory virus infections and the severity of these infections , according
