Histamine release from intestinal mast cells induced by staphylococcal enterotoxin A (SEA) evokes vomiting reflex in common marmoset
Fig 2
SEA binds with submucosal cells in the GI tract.
GI tissues (stomach, duodenum, jejunum, ileum, cecum and colon) were obtained from a common marmoset. Frozen tissues were sectioned (10 μm) and incubated with SEA (1.0 μg/ml) for 60 min at room temperature. After washing the sections with PBST, the sections were stained for SEA using rabbit anti-SEA antibody and Alexa 488-conjugated goat anti-rabbit IgG. Magnification, x20. Each scale bar is equal to 50 μm.
