ABSTRACT
Objective To probe into the pathogenesis of gestational diabetes mellitus (GDM) by studying expression of TLR4 acetylation in peripheral blood mononuclear cells of gravida with GDM as well as its role in TLR4 inflammatory pathway. Methods 30 normal gravidas and 30 gravidas with GDM were enrolled in the study, 15 mL peripheral blood from every participant was collected for extraction of mononuclear cells via density gradient centrifugation and culturing in vitro by LPS. The expression of TLR4 acetylation in the mononuclear cells was detected using immunoprecipitation and western blot and the levels of inflammatory cytokines, TNF-α, IL-1 and IL-10 in the supernatant were detected by ELISA. Results TLR4 acetylation appeared positive in GDM group, and negative in the control group. After the LPS intervention, the degree of TLR4 acetylation was enhanced significantly and the latter was significantly higher than those of the GDM group and the normal + Lps group (P < 0.05). The differences in the levels of inflammatory cytokines, TNF-α, IL-1, IL-10, were statistically significant (P < 0.05). Conclusion TLR4 acetylation exists in mononuclear cells of gravida with GDM, and mediates the release of inflammatory cytokines by influencing the activation of TLR4 inflammatory pathobenesis, which contributes to the promoted antiinflammatory - proinflammatory imbalance in gravidas. In this way, it is involved in the growth of GDM.
