Direct action of a protein-bound polysaccharide, PSK, on transforming growth factor-beta.

Abstract

We investigated the action of a protein-bound polysaccharide, PSK, on transforming growth factor-beta (TGF-beta). (1) In in vitro-mixed culture of peripheral blood mononuclear cells (PBMC) from healthy human and mitomycin C-treated human colon cancer cells, PSK or polyclonal antibody to TGF-beta significantly enhanced incorporation of 3H-thymidine into PBMC… (More)
