title: [Autoantibodies to the thymus and skin epithelium in NZB/N mice and (NZBxNZW)F1 hybrids].
abstract: Antibodies reacting with thymus and skin epithelial cells were revealed by indirect immunofluorescence in sera of NZB/N mice and (NZB X NZW)F1 hybrids (B/W) 1-2 and 4-5 months of age. Similar antibodies were not found in sera of BALB/c mice. The inhibition experiments with DNA have shown that antibodies reacting with the thymus and skin epithelium differ from those reacting with the cellular nucleus. Positive reactions with the epithelium were obtained in all thymus and skin tissue samples of humans, guinea-pigs and NZB/N, B/W and BALB/c mice, including autologous tissues of NZB/N and B/W mice. Thus, antibodies reacting with thymus and skin epithelial tissues belong to autoantibodies. These autoantibodies are revealed during the first month of life before the onset of autoimmune processes. The role of these autoantibodies in the damage of thymus epithelium and the development of immunoregulatory disturbances, typical of autoimmune processes, needs further study.
