Suppression of experimental allergic encephalomyelitis in guinea-pigs with poly-L-lysine.
Poly-L-lysin (PLL) given subcutaneously in a dose of 3 mg/day suppresses experimental allergic encephalomyelitis in guinea-pigs. The suppressive effect of PLL can still be demonstrated when administration is begun 8 days post-immunization. The effect is disease- and species-specific since PLL (3 mg/day) does not suppress experimental allergic orchitis in guinea-pigs, nor does it suppress EAE in rats (1-5 mg/day). PLL (0-2 mg/day) does not decrease the severity of graft-versus-host disease (GVH) in mice as judged by the spleen/body weight assay.
