Protective effect of syngeneic antitumor serum on mammary tumor in a syngeneic host

The possibility of passive immunotherapy was examined using syngeneic antitumor serum, which could lyse tumor cells in co-operation with immune or activated macrophages. Intraperitoneal injection of syngeneic antiserum into mice soon after inoculation of MM46 tumor cells clearly suppressed peritoneal or subcutaneous tumor growth. However, the antiserum did not suppress an established tumor. The tumor-specific synantibody responsible for the protection was shown by gel filtration to be in the IgG fraction, not the IgM fraction.

Breast Tumorigenesis

Breast tumorigenesis involves the production or formation of tumor(s) in breast tissue. Discover the latest research on breast tumorigenesis here.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
