ABSTRACT

Objective:

To stimulate the PBMCs of systemic lupus erythematosus patients with recombinant human high mobility group box1 (HMGB1) protein,observe the effect of HMGB1 on the expression of LC3Ⅱ/Ⅰ protein in active lupus nephritis and inactive lupus nephritis patients.Evaluate the effect of recombinant human high mobility group box 1 ( HMGB1 ) on the proliferation of PBMCs in patients with SLE.

Methods:

Western blot was used to detect the expression of LC 3II/I protein in PBMCs of active lupus ne-phritis and inactive lupus nephritis patients after stimulated by 1 μg/ml HMGB1 for 0,6,24 and 48 h.CCK-8 assay was used to detect the effects of PBMCs proliferation in patients with SLE after 1 μg/ml HMGB1 stimulation 72 hours.The statistical software SPSS17.0 was used to analyzed the results.

Results:

Western bolt showed an increasing expression of LC 3Ⅱ/Ⅰ protein in SLE patients after stimulated by HMGB1 ( P<0.05 ) , and this effect was time dependent.Compared with inactive lupus nephritis group , the increasing level of autophagy in active lupus nephritis group was more obviously.1 μg/ml HMGB1 could inhibit the proliferation of PBMCs in patients of SLE significantly ( P<0.001 ).

Conclusion:

HMGB1 may promote autophagy in SLE especially patients with active lupus nephritis and involved in the pathogenesis of SLE and lupus nephritis.Monoclonal antibodies targeting to HMGB 1 or modulators of mam-malian autophagy may provide new way for the treatment of SLE especially LN.
