TNFRSF1B and systemic lupus erythematosus: In our experiment, compared to healthy controls, the percentage of TNFRI was increased in SLE BMSCs, while preincubation of BMSCs with TNF-α together with TNFRI neutralizing mAb instead of TNFRII neutralizing mAb significantly restored the capacity of SLE BMSCs migrating and in vivo homing, demonstrating that TNF-α decreased SLE BMSCs migration via a specific TNFRI manner.
