Analysis of B Cells From Autoimmune Individuals

Analysis of B Cells From Autoimmune Individuals


Lead Sponsor: University of Colorado, Denver

Source University of Colorado, Denver
Brief Summary

This observational study aims at finding out if individual with autoimmunity exhibit increased numbers of B cells that express two types (instead of one type) of antibodies, and if B cells of individuals genetically susceptible to autoimmunity display defects in the biological process of tolerance, which removes B cells that participate in autoimmunity.

Detailed Description

Peripheral blood B cells of SLE patients are analyzed by flow cytometry to determine the frequency of B cells co-expressing immunoglobulin kappa an lambda light chains. This frequency is correlated to the disease activity.
