Abstract:
Objective To explore the changes of the amount and function of Vα24~+Vβ11~+,CD161~+Vα24~+NKT cells in the peripheral blood of systemic lupus erythematosus (SLE) patients. Methods The amount of Vα24~+Vβ~+,CD16~+Va24~+NKT cells in the peripheral blood of 30 SLE cases and 30 healthy persons were detected by flow cytometry. Results Vα24~+Vβ11~+,CD161~+Vα24~+NKT cells in the peripheral blood of SLE patients were significantly lower than that of normal control (P < 0.05). Vα24~+Vβll~+ and CD161~+Va24~+NKT cells in the pe-ripheral blood of SLE patients positively correlated with the level of the complement (C3,C4) and negatively correlated with SLE disease ac-tivity index (SLEDIA) and ESR. Conclusion Activated NKT cells decreased in the peripheral blood of SLE patients. Vα24~+Vβ11~+ and CD161~+Vα24~+NKT cells might be involved in the pathogenesis and development of SLE.
