HF bound to DV-antigen in an immunosorbent column and enhanced only the DV- specific PFC.

Findings suggest that plasticity within specific PFC regions modulates the type and degree of social bias that individuals' exhibit.

The SF is adsorbed on live or heat-killed mouse peritoneal macrophages and transmits DV- specific PFC in spleen after i.p.

SF suppressed DV- specific PFC in syngeneic spleen cells and was adsorbed on syngeneic macrophages, but not on those from allogenic animals.
