Definition

A powder formulation containing a triple helix beta-glucan, isolated from the cell walls of the shiitake mushroom (Lentinula edodes), with potential immunostimulating activity. The beta-glucan in beta-glucan MM-10-001 binds to a lectin site within the complement receptor 3 (CR3 or iC3b receptor) on leukocytes, priming the receptor to trigger cytotoxic degranulation of leukocytes when leukocyte CR3 binds to iC3b-opsonized tumor cells. iC3b is the proteolyticly inactive product of the complement cleavage fragment C3b.
