Up to 60% of patients with systemic lupus erythematosus (SLE) experience autonomic symptom. Sympathetic nervous system damage can cause dysfunction of the bone marrow that activates inflammatory cells, potentially causing multiple organ damage. We hypothesized that sympathetic nervous system damage would induce bone marrow dysfunction with multiple organ damage in SLE, and that multiple organ damage could be improved by therapy targeting the nervous system. Here, we showed that damage to autonomic nerves and Schwann cells occurred in the bone marrow and central nervous system of SLE model mice. A neurotoxic drug increased mortality and induced severe neuropathy and multiple organ damage, while a neuroprotective drug prevented multiple organ damage. The administration of bone marrow-derived mesenchymal stromal cells (BMSCs) cultured on a 3-dimensional fiber scaffold improved bone marrow neuropathy, skin lesions, kidney function, and mortality. Our results reveal that bone marrow neuropathy influence multiple organ damage associated with SLE, and improvement of bone marrow neuropathy by intrathecal injection of BMSC may be a target for SLE multiple-organ damage.
