Specific inflammatory cytokines (TNF-α, IL-6) and signaling pathways (JNK, NF-κB, JAK-STAT) directly impair insulin signaling by causing serine phosphorylation of IRS-1 and reducing GLUT4 expression.
Understanding that inflammation directly blocks insulin action at the cellular level explains why anti-inflammatory strategies or weight loss can improve metabolic health.

TNF-α causes insulin resistance by enhancing adipocyte lipolysis stimulating JNK and IKKβ/NF-κB pathway which may increase serine/threonine phosphorylation of IRS1. IL-6 induces IR by reducing the expression of GLUT4 and IRS-1 by activating the JAK-STAT signaling pathway...

- Obesity-induced chronic low-grade inflammation causes insulin resistance by activating proinflammatory cytokines (TNF-α, IL-6) and signaling pathways (JNK, NF-κB, JAK-STAT), which interfere with insulin signaling and action.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
