摘要

We studied the expression of reversion-inducing cysteine-rich protein with Kazal motifs (RECK) on peripheral blood mononuclear cells (PBMCs), the serum concentration of matrix metalloproteinase 9 (MMP-9) and the MMP-9 secretion ability of PBMCs in patients with systemic lupus erythematosus (SLE), and clinical features were assessed. Compared with PBMCs from healthy donors, PBMCs from SLE patients expressed less RECK protein and mRNA but secreted more MMP-9. The serum concentration of MMP-9 was, however, lower in SLE patients than in healthy donors. The level of RECK protein was inversely associated with the Systemic Lupus International Collaborating Clinics (SLICC) Damage Index (SDI) and MMP-9 secretion in SLE, but no relationship was found between serum MMP-9 concentration and the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). In conclusion, the level of RECK protein expressed in PBMCs could be used to predict organ or system damage in SLE and this might help in developing new therapies for SLE targeted at MMP-9.
