IL1B and obesity due to melanocortin 4 receptor deficiency: Taken together, we showed that obesity and maladjusted lipid metabolism in ORG lead to renal lipid accumulation and podocyte injury, which are partially mediated by CD36; CD36-mediated lipid accumulation activates NLRP3 inflammasome, releases inflammatory factor IL-1β, and induces podocyte injury of ORG; inhibition of CD36 also inhibits NLRP3 activation inflammasome and ameliorates podocyte injury (Figure 10).
