Generation and characterization of two monoclonal self-associating IgG rheumatoid factors from a rheumatoid synovium

Arthritis Rheum. 1992 Jan;35(1):101-5. doi: 10.1002/art.1780350115.

Abstract

Objective: To study IgG rheumatoid factor (RF) from rheumatoid synovium.

Methods: We fused the K6H6/B5 human-mouse heterohybridoma with unstimulated rheumatoid synovial B cells to generate IgG-RF-secreting hybridomas.

Results: The RFs from 2 such hybridomas bound specifically to the Fc fragment of human IgG and self-associated to form immune complexes. Such immune complexes are a major characteristic of the pathogenic IgG-RFs in rheumatoid synovium.

Conclusion: IgG-RF-secreting hybridomas have been obtained. Analyses may reveal the underlying mechanisms of the induction of IgG-RF.
