Immunomodulating activities associated with the cytosol fraction of a 3-methylcholanthrene-induced rat fibrosarcoma--II. Association with polyamine complexes.
This paper characterizes the molecular nature of the factors present in cytosol from F-344 rat McFiFi2(s) fibrosarcoma cells (FiCF) which mediate inhibition of PHA-induced lymphoproliferative responses. These are polyamines (spermine/spermidine) conjugated to different protein carriers. Interaction of these complexes with polyamine oxidase (PAO) present in fetal calf or rat serum is responsible of the suppression observed.
