Expansion of neonatal tolerance to self in adult life: II. Tolerance preferentially spreads in an intramolecular manner.
Newborn rats exposed to a myelin basic protein determinant acquired long-lasting resistance to experimental autoimmune encephalomyelitis induced by another determinant only if both determinants are co-administered in adult life. We demonstrate here that during the course of disease both the anti-self response and the tolerant state spread in an intramolecular and not an intermolecular manner. Mechanisms involved in tolerance elicitation and expansion are then explored using an in vitro system in which indirect suppression could be measured.
