Abstract
Systemic adoptive immunotherapy with specifically immune lymphocytes was successfully performed in immunodepressed mice challenged intracerebrally with L5178Y/DTIC lymphoma cells, a tumor subline rendered highly immunogenic through In vivo exposure to 5‐(3,3‐dimethyl‐1‐triazenyl)‐1H‐imidazole‐4‐carboxamide (DTIC)^1^. The systemic immunotherapy relied on the infusion of in vitro‐generated primary cytotoxic T‐lympho‐cytes (CTL), the anti‐tumor activity of which was evaluated by measuring tumor‐cell proliferation In the brain in terms of radiolabel uptake and by recording survival times of recipient leukemic mice. The protection afforded by CTL appeared to be specific and was largely conditioned by dose and time of CTL administration. The levels of protection correlated well with the in vitro killing of L5178Y/DTIC tumor cells.

The relationship between induction of novel immunogenicity by xenogenizing chemicals and DNA-methylating activity in murine tumors was investigated at the clonal level in L1210Ha cells treated with 5-azacytidine, N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) or 1-(p-chlorophenyl)-3,3-dimethyltriazene
## Abstract In previous reports, we demonstrated that adoptively transferred T cells homed to the tumor site (among other sites) and that amplification of immune responses occurred __in situ__ leading to the generation of cytotoxic CD8^+^ tumor‐infiltrating lymphocytes (TIL) and macrophages. The pr
We have cloned a mouse homologue (designated Myak) of the yeast protein kinase YAK1. The 1210 aa open reading frame contains a putative protein kinase domain, nuclear localization sequences and PEST sequences. Myak appears to be a member of a growing family of YAK1-related genes that include Drosoph
