IL1B and obesity disorder: Another important inflammatory mediator involved in obesity is IL-1β, a cytokine whose secretion requires its processing by caspase-1 as the result of the activation of the nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing 3 (NLRP3) inflammasome, a multimeric cytosolic protein complex activated by pathogen-associated molecular pattern (PAMP) and danger-associated molecular pattern (DAMP) molecules [38].
