Obesity-related type 2 diabetes (T2D) emerges from a chronic immuno-endocrine imbalance in which inflammatory cytokines and adipokines remodel insulin signaling, substrate partitioning, and β-cell resilience. Hypertrophic, hypoxic adipose tissue (AT) recruits and reprograms immune cells, driving secretion of tumor necrosis factor-α (TNF-α), interleukins (IL-1β, IL-6, IL-18), chemokines (e.g., CCL2/MCP-1), and alarmins that activate stress kinases (JNK/IKK), SOCS proteins, and the NLRP3 inflammasome. In parallel, the adipokine milieu shifts like adiponectin declines; leptin, resistin, RBP4, chemerin, and lipocalin-2 often rise, tilting systemic physiology toward insulin resistance (IR), dyslipidemia, and endothelial dysfunction. These signals converge across organs: in the liver, cytokine and lipid cues sustain gluconeogenesis and steatosis; in muscle, lipid-derived metabolites and cytokines blunt GLUT4 translocation; in islets, IL-1β, TNF-α, and leptin resistance impair insulin secretion and promote β-cell stress. Endocrine and paracrine crosstalk is bidirectional; adipokines modulate immune tone, while immune mediators reshape adipocyte function and adipogenesis. Therapeutically, weight loss, physical activity, and metabolic surgery attenuate metaflammation and normalize adipokines. Pharmacotherapies (metformin, thiazolidinediones, SGLT2 inhibitors, and incretin-based agents) indirectly and sometimes directly recalibrate cytokine/adipokine networks. Targeted immunometabolic approaches like IL-1 pathway blockade, NLRP3 inhibition, chemokine-axis modulation, selective PPAR agonism, and experimental adiponectin receptor agonists offer precision opportunities but demand careful safety assessment. This review integrates mechanistic insights, tissue crosstalk, and translational evidence to map how cytokines and adipokines drive the path from obesity to T2D and to highlight practical levers to restore immuno-endocrine homeostasis.
