Chronic inflammation is linked to the development and progression of various non-communicable diseases, and Toll-like receptor 4 (TLR4) plays a crucial role in chronic inflammation. Bioactive compounds have the potential to modulate the TLR4 pathway and alleviate inflammation.
Chronic inflammation is associated with the development and progression of several non -communicable diseases, such as diabetes, cardiovascular disease, chronic kidney disease, cancer, and nonalcoholic fatty liver disease. Evidence suggests that pattern recognition re-ceptors that identify pathogen-associated molecular patterns and danger-associated molec-ular patterns are crucial in chronic inflammation. Among the pattern recognition receptors, Toll-like receptor 4 (TLR4) stimulates several inflammatory pathway agonists, such as nu-clear factor -KB, interferon regulator factor 3, and nod-like receptor pyrin domain containing 3 pathways, which consequently trigger the expression of pro-inflammatory biomarkers, in-creasing the risk of noncommunicable disease development and progression. Studies have focused on the antagonistic potential of bioactive compounds, following the concept of food as a medicine, in which nutritional strategies may mitigate inflammation via TLR4 modula-tion. Thus, this review discusses preclinical evidence concerning bioactive compounds from fruit, vegetable, spice, and herb extracts (curcumin, resveratrol, catechin, cinnamaldehyde, emodin, ginsenosides, quercetin, allicin, and caffeine) that may regulate the TLR4 pathway and reduce the inflammatory response. Bioactive compounds can inhibit TLR4-mediated inflammation through gut microbiota modulation, improvement of intestinal permeability, inhibition of lipopolysaccharide-TLR4 binding, and decreasing TLR4 expression by modu-lation of microRNAs and antioxidant pathways. The responses directly mitigated inflam-mation, especially nuclear factor -KB activation and inflammatory cytokines release. These findings should be considered for further clinical studies on inflammation-mediated dis-eases.(c) 2022 Elsevier Inc. All rights reserved.
