Genetic analysis of CR1 expression on erythrocytes of patients with systemic lupus erythematosus.


The role of genetic factors in decreased expression of CR1 in patients with systemic lupus erythematosus (SLE) was investigated by assessing the frequency of genotypes determining the numbers of CR1 on erythrocytes obtained from 52 patients with SLE and from 84 normal individuals. The expression of CR1 was quantitated using flow cytometry. Genotypes were… (More)
