Inflammation inducer

The term 'Inflammation inducer' is a broad functional descriptor rather than a specific molecular target such as a protein, enzyme, or receptor. It encompasses a diverse range of exogenous and endogenous stimuli that trigger the innate immune system to initiate an inflammatory response [1]. Exogenous inducers include Pathogen-Associated Molecular Patterns (PAMPs), such as bacterial lipopolysaccharides (LPS) or viral RNA, while endogenous inducers consist of Damage-Associated Molecular Patterns (DAMPs), such as high-mobility group box 1 (HMGB1) or extracellular ATP, which are released during tissue injury or cellular stress [2]. These agents typically act as ligands for various pattern recognition receptors (PRRs), including Toll-like receptors (TLRs) and NOD-like receptors (NLRs), leading to the activation of downstream signaling pathways such as NF-κB and the assembly of inflammasome complexes [3]. In drug discovery and preclinical research, chemicals like carrageenan or phorbol esters are frequently employed as experimental 'inflammation inducers' to create disease models for testing anti-inflammatory candidates [4]. Because this category is heterogeneous and non-specific, there are no drugs that target an 'inflammation inducer' as a single entity; rather, therapeutic interventions are directed at the specific receptors or the pro-inflammatory cytokines (e.g., TNF-α, IL-1β) that these inducers elicit [2, 5].
