Psoriasis specific chromosomal proteins, antibodies against them and disease activity.
It has been demonstrated recently that the lymphoid cells of patients with psoriasis have antibodies directed against the psoriasis specific non-histone proteins. A conceptual hypothesis for the role of these antibodies in the pathogenesis of psoriasis presented in this communication, is as follows. Perhaps the psoriasis specific non-histone proteins following phosphorylation bind to histone which keeps psoriasis gene(s) repressed. This may result in the displacement of histone from the DNA. Antibodies against psoriasis specific non-histone proteins may facilitate the displacement of histone. DNA set free, possibly containing psoriasis gene(s), can then be transcribed into RNA causing a shift of the resting pool of keratinocytes in the symptom-free skin of psoriasis patients to the proliferating pool of keratinocytes in the psoriasis lesions.
