Cytochalasin B, a metabolic product of several fungi, enhances up to 10-fold the sensitivity and reactivity of human leukocytes to antigen E or anti-IgE-mediated histamine release. The effect of cytochalasin B is a result of its action on the second, antigen-independent, stage of histamine release. These data suggest that normally, antigen-triggered histamine release is modulated by a cytochalasin-sensitive barrier (CSB). This CSB modulation of histamine release can be separated from the modulating effect of cyclic adenosine monophosphate (AMP).
