Fluorescent patterns of antibodies to mitochondria, endoplasmic reticulum and ribosomes.

The fluorescent patterns of autoantibodies to mitochondria, endoplasmic reticulum and ribosomes are described. Mitochondrial autoantibodies can be now divided in 10 types, microsomal antibodies at least in 3 types. Using rat renal tissue sections the typical fluorescent pattern of new antimitochondrial antibodies were: type 7, distal tubulus and third portion of proximal tubules, type 8 distal tubules, only, type 9 first and second portion of proximal tubules, type 10 strong reaction of distal and third portion of proximal tubules. The new pattern of ribosomal antibody is characterized by a cytoplasmic staining of rat hepatocytes especially in the central area of the liver lobule. The heterogeneity of cytoplasmic autoantibodies can be used as a diagnostic marker in different pathological conditions, if the different staining patterns is taken into account.
