title: Hybrid resistance to BALB/c plasmacytomas. II. Radiation sensitivity and silica insensitivity of resistance to MPC-11.
abstract: Resistance to the BALB/c plasmacytoma MPC-11 by F1 hybrids between BALB/c and four C57BL/10 congenic resistant strains was abrogated or reduced by 450 rads total body irradiation but was unaffected by intravenous injection of 3 to 4 mg of silica. The results are consistent with the idea that hybrid resistance to MPC-11 depends on an active immune response and is different from Hh-1 controlled hybrid resistance.
