Abstract
Peripheral blood T lymphocytes from 29 of 31 patients with rheumatoid arthritis incorporated significant quantities of thymidine when cultured with pooled human immunoglobulin G (IgG). In contrast to the observation of general reactivity to pooled Igg, responses to pooled IgM were rare (3 of 26 patients). None of 11 controls responded to either IgG or IgM. Response to IgG is maximal on day 6 of culture and is dependent on concentration of IgG. The responding cells recognize determinants on monoclonal light chains and/or Fab fragments. Response to light chains follows one of three patterns: preferential response to lambda chains, preferential response to kappa chains, and essentially equal response to either kappa of lambda chains.
