| pubmed-article:2503955 | pubmed:abstractText | The immune status, the level of expression of class II HLA histocompatibility antigens in the peripheral blood cells, and the effects on this antigen expression of alpha- and gamma-interferons have been examined in 21 patients with psoriatic arthropathy. Examinations of the immune status have revealed reduced levels of T-lymphocytes, of active E-RFC, of cells forming rosettes with autologous red cells, and an increased count of 0-lymphocytes. The level of class II antigen expression in monocytes, in total lymphocyte population, and in the fraction enriched for B-lymphocytes is much reduced in all the patients suffering from psoriatic arthropathy. The level of these antigens' expression in T-lymphocytes is increased in 2/3 of patients and unchanged in the rest. Intranasal alpha-interferon increased class II antigen expression in the peripheral blood monocytes of patients, whereas gamma-interferon induced no such effect. The stimulating effect of alpha-interferon on the patients' monocytes has been much less manifest than on normal donor monocytes. The antigen expression in the patients' blood lymphocytes exposed to alpha- and gamma-interferons has been virtually the same. | lld:pubmed |
