[Immunological responsiveness in C57BL/6 mice during the growth of a tumoural graft: the Lewis' lung carcinoma (author's transl)].

Using antibody and delayed type hypersensitivity responses to sheep red blood cells, immunological responsiveness was studied during the course of 3LL tumor growth. Acquired specific resistance to Listeria monocytogenes of tumor bearing mice was also investigated. Experimental results obtained, showed that the ability of 3LL bearing mice to establish a specific immune response is not markedly impaired.
