ABSTRACT
BACKGROUND:In recent years,studies have shown that obesity is closely related to chronic inflammation.Due to excessive energy intake,inflammatory macrophage infiltration and inflammatory response occur in visceral adipose tissue,which is crucial for the regulation of adipose tissue fibrosis. OBJECTIVE:To summarize the molecular mechanism of inflammation-related signals involved in the regulation of adipose tissue fibrosis and to provide reference for the treatment of adipose tissue fibrosis and related metabolic diseases through anti-inflammatory pathways. METHODS:Relevant documents were retrieved from CNKI and PubMed,and the Chinese and English search words were"inflammation,inflammatory factors,inflammatory signals,lip fibrosis,adipose fibrosis,adipose tissue fibrosis"respectively.The search period was from January 2003 to December 2022.Finally,52 documents meeting the criteria were included for review. RESULTS AND CONCLUSION:During obesity,visceral adipose tissue expands through adipocyte proliferation and hypertrophy to store excess energy,and defects caused by remodeling or functional changes mainly include impaired angiogenesis,adipocyte apoptosis promoted by white adipose tissue hypoxia,macrophage infiltration,and adipocyte fibrosis.Adipose tissue fibrosis has adverse effects on the natural growth of adipose cells.The factors that trigger chronic inflammation of adipose tissue include a variety of signal stimuli,such as adipocyte death caused by hypoxia,mechanical signal transduction caused by extracellular matrix remodeling and lipogenic factor imbalance.Inflammatory factors such as interleukin-1β,tumor necrosis factor-α,C-type lectins and adiponectin secreted by adipocytes and other inflammatory signaling pathways such as nuclear factor-κB,transforming growth factor-β/Smad and MAPK jointly regulate the process of adipose tissue fibrosis.
