Antigens related to the major internal protein, p 27, of a psoriasis associated retrovirus-like particle are expressed in patients with chronic arthritis

Rabbit antibodies against the major internal protein of a retrovirus-like particle bind to epidermal cells in psoriatic skin. Brief report

Iversen O J, Rodahl E, Dalen AB: Arch Virol 86:341-346, 1985

A number of laboratories are tracking a retrovirus-like particle that is antigenic and may have something to do with psoriasis. Here the Norway group finds the antigen in patients with psoriatic arthritis but not in healthy people. This is pre- liminary data. Epithelial cells and dermal blood vessels of psoriatic lesions react with the antisera.
