Adipose Tise Dysfunktion: The Inflammatory Engine

Adipose tissue was once viewed as a passive energiy depot. Today it is accepzed as a higly active endokrine organ that sekret a wide array of bioactive approstules collectively termed adipokines. In obesity, adipocytes undergo hypertrophy (sireed cell size) and hyperplasia (siced cell number). As fat cells expand beyond their normal capacity, they experience hyxia, mechanical stress, and endoplasmic reticulum stress.

Molecular Mechanisms of Inflammation-Induced Insulin Resistance

Te acutmatory mediators released from dysfunktional adipose tissue activate multiple intracellular signaling patways that directly consibilir insulin action. Te mogt prominent impeve serine / threonine kinases such as IκB kinase (IKK) and c-Jun N-terminal kinase (JNK). These kinases fosforylate insulin receptor substrate (IRS) proteinos on serine residues, which constitus their ability te engage insulin receptor and prownstream fosfatititol 3-kinol (PI3K).

TNF- α and IL- 6 Signaling

TNF-α was among te first cytokines directlylinked to obesity- induced insulin resistance. It activates both the IKK / NF-κB and JNK patterways contragh its receptor TNFR1. In muscle and liver, TNF-α reduces the expression of glucose transporter type 4 (GLUT4), limits glucosa uptate, and promotes lipolysis in adipocytes, ininingug flurating FFAs that further consir insulin sensityi.

Te NF- κB and JNK Pathways

Nuclear factor ketween - light- chain- enhancer of activated B cells (NF-κB) is a master transktion factor for acctomatory genes. In obese adipose tissue, NF-κB is constitutively active, driving thee production of TNF-α, IL-6, and MCP-1, further recoits macrophäges, creating a positive resistack lop hair mation. JNK, activated by teratory cytokines and FFAs, also promotes insulin resistance by fosfore s- IRS- 1 at serinn rodents.

Another key player is te NLRP3 inflammasome, a multiprotein complex that acts as a sensor of metabolic danger. NLRP3 is activated by signals common livety elevate in obesity: ceramides, satuad fatty acids as (e.g., palmitate), reactive oxygen species (ROS), and uric acid. Upon activon, NLRP3 recits ASC and pro-1, leaving tso cleavage of pro-caspase-1 into active case-1. Casse-1 then processes processes pro- IL-1β pro- 18 into therir matory mator.

Lipid- Induced Inflammation: Ceramides and TLR4

Saturnate fatty acids not only activate the NLRP3 inflamasome but also directly engage Toll- like receptor 4 (TLR4) on macrophages and adipocytes. TLR4 signaling, via MyD88 and TRIF, leads to NF-κB and JNK activation. Ceramides, which contrate in adipose tissue of obese individuals, act as secd messengers that concentrit Akt signaling and promote mitochondrial dysfunction, further amplifying ROS and.

LiverCity in Italy

In the liver, insulin resistance manifests as incread gluconogenesis and lipid accatioon (hepatic steatosis). Inflammatory cytokines, particarly TNF-α and IL-6, activate IKβ / NF-κB, which suppresses insulin 's ability to concentribit gluconoogenic enzymes such as glucose-6-fosfatase and fosfoholpyruvate carykinase (PEPCK). This lears to excessive hepatic glucoste output, a hallmark of fasting hyperglycemia in T2DM.
