Lymph node cells from rats immunized with sciatic nerve in Freund's adjuvant demyelinate trigeminal ganglion cultures. Rabbit antiserum to rat immunoglobulin A blocks this cytodestructive event. The antiserum may act by combining with IgA on the lymphoid cell surface, preventing the interaction of cell-bound antibody and tissue anitigen.
