Susceptibility to Proteolipid Apoprotein and Its Encephalitogenic Determinants in Mice

Abstract

We investigated in mice strain differences in induction of experimental allergic encephalomyelitis by proteolipid apoprotein and studied encephalitogenic determinants. SJL/J, C3H/He, CBA/J and A/J mice were high responders, BALB/c and AKR/J mice were moderately susceptible, and DBA/2, B6 and congenic strains of B10 background were low responders. Synthetic peptide 136-150 was encephalitogenic for SJL/J mice, and 215-232 was encephalitogenic for C3H/He mice. These encephalitogenic derterminants are present in the extracellular portion of proteolipid apoprotein in myelin.
