Antitumor immunity in strain 2 guinea pigs immunized with potassium chloride extracts of L2C tumor cells. 1978

D P Braun, and J C Hengst, and M B Mokyr, and S Dray

Extracts of L2C tumor cells stimulated in vitro production of macrophage migration inhibitory factor (MIF) in peritoneal exudate cells from guinea pigs immunized with L2C tumor cells. Guinea pigs immunized with extracts of L2C tumor cells that were active in vitro (in the MIF assay) were completely resistant to challenge with viable tumor cells given 2 weeks later. Furthermore, guinea pigs immunized with extracts of L2C tumor cells within 1 hour after challenge with viable L2C tumor cells survived substantially longer than did nonimmunized controls. The immunoprotective and immunotherapeutic effects seen in guinea pigs given injections of viable L2C tumor cells were obtained with extracts of L2C tumor cells but not with extracts of another guinea pig tumor (line 10 hepatoma) or with extracts of normal guinea pig lymphoid cells.

D005620	Freund's Adjuvant	An antigen solution emulsified in mineral oil. The complete form is made up of killed, dried mycobacteria, usually M. tuberculosis, suspended in the oil phase. It is effective in stimulating cell-mediated immunity (IMMUNITY, CELLULAR) and potentiates the production of certain IMMUNOGLOBULINS in some animals. The incomplete form does not contain mycobacteria.	Freund Adjuvant,Adjuvant, Freund,Adjuvant, Freund's,Freunds Adjuvant

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
