***< 0 We generated a heterodimeric Fc fusion protein, GBP1+6-Fc, by separately fusing GBP1 and GBP6 to oppositely polarized Fc fragments that can only bind to each other and not homodimerically (Fig 2C)

Based on an model of mouse podocyte injury, Age groups decreased the proliferation of podocytes and improved the expression of CXCL9 and C-X-C motif chemokine receptor 3 (CXCR3), and advertised the activation of signal transducer and activator of transcription 3 (STAT3). with specific siRNA significantly improved the proliferation and decreased the apoptosis of the podoyctes. Moreover, the levels of inflammatory factors, such as tumor necrosis element (TNF)- and interleukin (IL)-6 were also decreased in the podoyctes transfected with siRNA-CXCL9, accompanied from the improved manifestation of nephrin and podocin, and decreased levels of Bax/Bcl-2 and triggered caspase-3. The knockdown of CXCL9 also led to the inactivation of the Janus kinase 2 (JAK2)/STAT3 pathway. Importantly, the use of the JAK2 inhibitor, AG490, and valsartan (angiotensin II receptor antagonist) attenuated the injury induced to mouse podoyctes by Age groups. On the whole, and to the best of our knowledge, this study demonstrates for the first time that Age groups exert pro-apoptotic and pro-inflammatory effects in mouse podoyctes through the CXCL9-mediated activation of the JAK2/STAT3 pathway. Therefore, our data provide a potential restorative target for DN. DN model of mouse podocyte injury induced by Age groups. We found that Age groups at numerous concentrations (10, 50, 100 and 150 mg/l) significantly inhibited the proliferation of mouse podocytes inside a concentration- and time-dependent manner (Fig. 2). After 72 h of incubation, the proliferation of podocytes treated with Age groups (10, 50, 100 and 150 mg/l) was suppressed by 13.310.11%, 22.70.17%, 43.80.25% and 54.60.41%, respectively. These findings indicated that treatment with Age groups inhibited the proliferation of podocytes inside a concentration- and time-dependent manner.
