(2) some patients are unable to wean themselves off glucocorticoid and face the risk of numerous adverse effects caused by long-term glucocorticoid dependence, such as glucocorticoid-related diabetes, femoral head necrosis, hypertension, stress ulcers, and infection, etc. Therefore, there is a strong unmet clinical need for more effective treatment for patients suffering from active SLE. Several preclinical studies have shown the efficacy of CAR-T cell treatment in SLE. The aim of this study is to investigate the safety, tolerability, preliminary efficacy, pharmacokinetics (PK), and pharmacodynamics (PD) of CD19 Universal CAR-γδT cells therapy in active SLE. Patients with active SLE will be invited to participate in the study, to receive CD19 Universal CAR-γδT cells intravenous infusion and follow-up visits of up to 2 years after enrollment.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.
