Membrane integrity changes upon viral infection activate sphingomyelinase SMPDL3B to restrict cGAS-STING signaling via cGAMP degradation Wang et al. find that cell membrane stress upon viral infection induces expression and stabilization of host sphingomyelin phosphodiesterase acid-like 3B (SMPDL3B), which, in turn, degrades cGAMP to s...

#WeekendRead! #FriendOrFoes?! Zhang &co show @cp-immunity.bsky.social that herpes simplex virus #HSV1 exploits changes in membrane integrity to activate a GPI-anchored hydrolase which degrades cGAMP preventing #cGAS/#STING activation & favoring virus infection
