Abstract
1. F1 hybrid rats that recovered from graft-versus-host (GVH) disease induced by the intraperitoneal injection of spleen cells of one parental strain showed varying degrees of resistance on re-challenge with cells of the same or of the other parental strain. Resistance to re-challenge, expressed either in terms of mortality or of severity of clinical manifestations, was greater after a strong than after a weak response to first challenge.
