Title: Effects of recombinant human interferons on rheumatoid arthritis B lymphocytes activated by Epstein-Barr virus. Author: Lotz M, Tsoukas CD, Curd JG, Carson DA, Vaughan JH. Journal: J Rheumatol; 1987 Feb; 14(1):42-5. PubMed ID: 3033238. Abstract: We evaluated the effects of all 3 classes of recombinant human interferon (IFN) on Epstein-Barr virus (EBV) infection of purified B lymphocytes from patients with rheumatoid arthritis (RA). After EBV infection, RA B cells secreted more IgM and significantly more IgM rheumatoid factor (RF) than normals. Spontaneous (no EBV) proliferation, IgM, and IgM RF were also higher in RA. All 3 types of IFN inhibited dose dependently EBV induced B cell activation. In RA, however, higher doses of each class of IFN were necessary to obtain 50% inhibition. IFN gamma was most potent in normals and RA. Four IgM RF production IFN gamma was significantly more potent than IFN alpha and IFN beta in reducing the spontaneous activation of RA B cells, and a similar trend was seen in B cell proliferation. These findings are discussed in the context of ongoing clinical trials with IFN gamma in RA.[Abstract] [Full Text] [Related] [New Search]
