Moreover, whether acute peritonitis correlated with the occurrence of celiac PVs was investigated by fluorescent staining with 4′,6-diamidino-2-phenylindole (DAPI) and Alexa Fluor 488 phalloidin, as well as immunofluorescent staining with CD11b and intercellular adhesion molecule-1(ICAM-1). Here, ITGAM is linked to peritonitis.
