摘要：

Bovine, rat, and mouse leukocytes were exposed to the pore-forming antibiotics alamethicin, suzukacillin, and trichotoxin isolated from the fungus Trichodermaviride. The compounds caused cell lysis around 5×10-5 mol/l; in rat mast cells histamine release was found simultaneously. For bovine and mouse lymphocytes, the compounds inhibited thymidine incorporation into DNA at sublytic concentrations around 2×10-6 mol/l. Lymphocyte stimulation by mitogens was inhibited at concentrations below 10-6 mol/l. We suggest that pore formation or alterations of membrane conductivity influence the proliferation of B- as well as of T-lymphocytes. © 1979.
