Elimination of CD8+ T cells in vivo does not break induced immunospecific tolerance to experimental allergic neuritis in rats.
The role of CD8+ T 'cytotoxic/suppressor' T cells in induced immunospecific tolerance and during recovery after actively induced disease was examined by means of elimination of CD8+ cells from Lewis rats using in vivo treatment by Ox8 monoclonal antibodies, in experimental allergic neuritis (EAN). Animals depleted of CD8+ T cells after recovery from EAN did not show any clinical signs of relapse. Other animals were pretreated with the peripheral nerve basic protein P2 and thereby rendered resistant to disease induction with a potentially neuritogenic emulsion. The elimination of CD8+ T cells did not result in EAN here either. Thus, the CD8+ T-cell population does not seem to participate in the suppression of this autoimmune disease under these experimental conditions.
