Resistance to Apoptosis and Elevated Expression of Bcl-2 in Clonally Expanded CD4+CD28− T Cells from Rheumatoid Arthritis Patients
1 Jul 1998
Abstract excerpt
Patients with rheumatoid arthritis have a subset of CD4+ T lymphocytes that are characterized by a defect in CD28 expression. CD4+CD28- T cells frequently undergo clonal expansion in vivo. These clonotypes include autoreactive cells and persist over many years. The clonogenic potential and longevity of these T cells could be related to an altered response to apoptosis-inducing signals. To explore this...
