The effects of protein-kinase-inhibitors (PKIs) on protein kinase C (PKCs) i.e., staurosporin, calphostin C, H-7, H-8, H-9, on phosphatidyl inositol 3-proteinkinase (PI3-K) i.e., wortmannin, and on protein tyrosine kinase (PTKs) i.e., genistein, herbimycin A, sanguinarin, lavendustin A and B were tested on the induction phase of the primary Ab-response in vitro. The inhibitory action of PKIs was the highest with herbimycin A, sanguinarin, H-9 and wortmannin. Although wortmannin inhibits the function of T-lymphocytes (Taub et al., 1997, Shi et al., 1997), we believe that this communication is the first report of PKIs immunosuppressive action on the inductive steps of Ab-formation.
