CD69 expression detected on lymphocytes near basal epidermal keratinocytes in a psoriatic plaque (PP skin) converted from symptomless (PN) skin. The human PN skin was grafted onto a SCID mouse, and injected intradermally with an autologous CD4+ T cell line as described in the text. A biopsy of the skin lesion created was processed for frozen section immunohistology using anti-CD69 monoclonal antibody (Becton-Dickenson, Mountain View, CA), avidin-biotin staining (Vectastain Kit, Vector Labs, Burlington, CA), with 3-amino-4-ethylcarbazole producing a positive red reactive product. Scale bar, 10 μm.
