What is the Origin of Metainflammation?

The concept is a portmanteau of "metabolic" and "inflammation," coined by researchers to specifically distinguish this chronic, sterile, and non-infectious inflammation from classic immune responses. Its recognition arose from studies showing that obesity and high caloric intake lead to the activation of inflammatory pathways in metabolic tissues. This term highlights the endocrine system's vulnerability to nutritional and lifestyle factors.

What is the Mechanism of Metainflammation?

Metainflammation is triggered by cellular stress signals, such as excessive lipid accumulation and endoplasmic reticulum stress within adipocytes and hepatocytes. These stressors activate intracellular signaling pathways, including NF-κB, which promotes the release of inflammatory adipokines and cytokines like TNF-alpha and Interleukin-6. These circulating mediators then interfere with insulin receptor signaling, leading to systemic insulin resistance and further metabolic and hormonal dysregulation.

Metainflammation

Meaning

A term used to describe a chronic, low-grade, and metabolically-driven inflammatory state that often arises in the context of nutrient excess and obesity. Unlike acute inflammation, this condition is characterized by a persistent, subtle elevation of pro-inflammatory cytokines, particularly within metabolic tissues like adipose tissue, liver, and muscle. This sustained immune activation is a key driver of insulin resistance, type 2 diabetes, and cardiovascular disease, representing a critical link between metabolism and the immune system. It fundamentally disrupts normal endocrine signaling.
