CXCR5 and systemic lupus erythematosus: Given the observed distinct differences in CD19 MFI and in the proportions of CD11c + CXCR5-, CD11c-CXCR5+, and CD11c-CXR5- B cells particularly in the DN subset when SLE were compared with HD, we tested whether we could identify relations between these markers focusing on SLE samples.
