Syngeneic adoptive immunotherapy and chemoimmunotherapy of a Friend leukemia: requirement for T cells. 1975

J R Berenson, and A B Einstein, and A Fefer

The aim of the study was to determine which cell mediates adoptive immunotherapy and chemoimmunotherapy of a syngeneic transplantable Friend virus-induced leukemia (FBL-3). An adoptive immunotherapy model was developed in which adult C57BL/6 mice given a lethal dose (10(4)) of FBL-3 on day 0 were saved by treatment on day 1 with C57BL/6 spleen cells or peritoneal exudate cells (PEC) immune to FBL-3. Cells passed through a nylon wool column to remove B cells and macrophages or treated with carbonyl iron to remove phagocytic cells remained effective, whereas cells treated with anti-theta serum and complement were far less effective. For adoptive chemoimmunotherapy, mice inoculated with 10(7) FBL-3 were treated 5 days later with cyclophosphamide (CY) plus immune spleen cells. CY, with or without non-immune cells, prolonged survival but all mice died with leukemia, whereas mice given CY plus immune cells survived tumor-free. As an adjunct to CY, immune cells passed through nylon wool or treated with carbonyl iron remained quite effective whereas cells treated with anti-theta serum and complement were far less effective. Thus, immune thymus-derived lymphocytes were required for the adoptive immunotherapy of an early leukemia or chemoimmunotherapy of a disseminated leukemia.

D007111	Immunity, Cellular	Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.

D007167	Immunotherapy	Manipulation of the host's immune system in treatment of disease. It includes both active and passive immunization as well as immunosuppressive therapy to prevent graft rejection.	Immunotherapies
D007502	Iron Chelating Agents	Organic chemicals that form two or more coordination links with an iron ion. Once coordination has occurred, the complex formed is called a chelate. The iron-binding porphyrin group of hemoglobin is an example of a metal chelate found in biological systems.	Iron Chelates,Agents, Iron Chelating,Chelates, Iron,Chelating Agents, Iron

D008810	Mice, Inbred C57BL	One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D009757	Nylons	Polymers where the main polymer chain comprises recurring amide groups. These compounds are generally formed from combinations of diamines, diacids, and amino acids and yield fibers, sheeting, or extruded forms used in textiles, gels, filters, sutures, contact lenses, and other biomaterials.

D002845	Chromatography	Techniques used to separate mixtures of substances based on differences in the relative affinities of the substances for mobile and stationary phases. A mobile phase (fluid or gas) passes through a column containing a stationary phase of porous solid or liquid coated on a solid support. Usage is both analytical for small amounts and preparative for bulk amounts.	Chromatographies
D003520	Cyclophosphamide	Precursor of an alkylating nitrogen mustard antineoplastic and immunosuppressive agent that must be activated in the LIVER to form the active aldophosphamide. It has been used in the treatment of LYMPHOMA and LEUKEMIA. Its side effect, ALOPECIA, has been used for defleecing sheep. Cyclophosphamide may also cause sterility, birth defects, mutations, and cancer.
