STIM1 and pneumonitis: Among five in vivo studies, three studies failed to reveal a role for STIM1 in neutrophil recruitment in either a zymosan‐induced peritonitis (TLR‐2 signalling dependent), a S. aureus‐induced pneumonitis (among others TLR‐2 signalling dependent), and an immune complex (IC)‐induced pneumonitis (FcyR signalling dependent), using a Mrp8‐Cre‐lox (Clemens et al.
