Interestingly, we found similar populations of IL-10 producing cells from scRNA-seq of lupus-prone mice as these markers were expressed by the Phagocytic PB-PC and TIM-1 B Cell populations from pre-disease mice and the TACI/TNF B Cell and TIM-1 B Cell populations from active-disease mice. The gene discussed is TNFRSF13B; the disease is systemic lupus erythematosus.
