title: The expression of TNF-alpha receptors 1 and 2 on peripheral blood mononuclear cells in chronic inflammatory demyelinating polyneuropathy.
abstract: The proportion of peripheral blood mononuclear cells (PBMCs) expressing TNF-alpha and its receptors (TNFR1, TNFR2) and the serum concentrations of its soluble forms were analyzed by FACS and ELISA in the patients with chronic inflammatory demyelinating polyneuropathy (CIDP) and in controls. Elevated levels of TNFR2 were observed on blood T cells in CIDP and idiopathic polyneuropathy. Low levels of TNFR1 were detected on monocytes in the subgroup of patients with CIDP examined after treatment with intravenous immunoglobulin. However, the proliferative activity of PBMCs in CIDP was not influenced by soluble recombinant TNFR1. Our limited data suggested the exact role of TNF-alpha and its receptors need to study further in CIDP, as well as in idiopathic neuropathies.
