Decreased Growth Capacity of Passaged Gross Virus-Induced Mouse Lymphomas After Incubation with Antithymocytic Sera

ABSTRACT

AKR or C3H/HeJ transplanted mouse lymphomas, originally induced by Gross virus, could be neutralized by in vitro incubation with an immunosuppressive rabbit anti-mouse thymus cell serum. Neutralization was measured by significantly increased latent periods or decreased incidence (at a minimum of 90 days post-transfer) of lymphoma in syngeneic recipients of lymphoma cells incubated with antithymocytic serum when compared with syngeneic recipients of lymphoma cells incubated with normal rabbit serum.
