title: Activation markers on peripheral blood T cells from patients with active or inactive systemic lupus erythematosus. Correlation with proliferative responses and production of IL-2.
abstract: Using various monoclonal antibodies to T cell activation molecules it has been shown that purified T cells from patients with active systemic lupus erythematosus overexpress the 4F2, IL-2R (CD25), HLA-DR and T10 antigens. T cells from patients with inactive disease had increased expression of VLA-1 and HLA-DR. Increased T10 expression on T cells from patients with active disease correlated inversely with the production of IL-2, whereas expression of CD25 was slightly increased after 3-day culture with either PHA or anti-CD3. These results provide further evidence of the in vivo activation of T cells in SLE and suggest that such activation comes slowly to a halt upon disease remission.
