Growth factors such as fibroblast growth factors (FGFs), epidermal growth factor receptor (EGFR), plasminogen activator inhibitor type 1 (PAI-1), and placental growth factor (PlGF) play pivotal roles in modulating inflammation and metabolic processes. While FGF1 demonstrates protective effects by improving insulin sensitivity and reducing pro-inflammatory cytokines, FGF2 exacerbates adipose tissue inflammation via NLRP3 inflammasome activation. EGFR activation has been linked to obesity-related renal injury, while PAI-1 contributes to chronic inflammation in obesity-induced diabetes by inhibiting hepatocyte growth factor (HGF). Additionally, PlGF has been implicated in the regulation of immune cell differentiation in adipose tissue, further promoting systemic metabolic dysfunction. Understanding these molecular pathways is essential for developing targeted interventions to mitigate obesity-related complications. This review highlights the critical interplay between growth factors and obesity-related inflammation. Keywords— Obesity, inflammation, growth factors, health. I. INTRODUCTION Obesity, defined by an excessive accumulation of adipose tissue, has become a significant public health concern due to its association with various chronic diseases. Beyond its implications for energy storage and metabolism, obesity is now recognized as a major driver of chronic low-grade inflammation, a condition that predisposes individuals to metabolic disorders, cardiovascular diseases, and certain cancers (Gregor & Hotamisligil, 2018). The systemic inflammation observed in obesity originates primarily from adipose tissue, which functions as an active endocrine organ. This tissue secretes numerous pro-inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6), alongside adipokines like leptin and adiponectin, which are integral to the regulation of metabolic homeostasis (Lee et al., 2020). In recent years, protein growth factors, including insulin- like growth factors (IGFs) and vascular endothelial growth factor (VEGF), have emerged as critical components in the complex network linking inflammation and obesity. These growth factors are essential for cellular proliferation, differentiation, and repair and play a dual role in modulating inflammation and tissue remodeling. For instance, IGFs are involved in insulin signaling and metabolic regulation, while VEGF promotes angiogenesis, a process critical for expanding adipose tissue in obesity (Singh et al., 2019). However, the dysregulation of these growth factors in the context of obesity can exacerbate inflammatory pathways, contributing to systemic metabolic imbalances. The interplay between obesity-induced inflammation and protein growth factors has significant implications for health. Chronic low-grade inflammation can disrupt the delicate balance of pro- and anti-inflammatory signals, further exacerbating metabolic dysfunction. Meanwhile, growth factors act as both mediators and regulators within this dynamic, influencing processes such as adipose tissue expansion, immune cell infiltration, and vascular development (Zhao et al., 2021). The intricate relationship between these elements underscores the complexity of obesity as a multifaceted condition with systemic consequences. Understanding the mechanisms linking inflammation, obesity, and protein growth factors is vital for developing novel therapeutic interventions. By targeting specific pathways influenced by growth factors, researchers may identify strategies to mitigate obesity-associated inflammation and its complications. This review aims to elucidate the fundamental connections between these factors, providing insights into their roles and potential implications for disease prevention and management. II. METHODS This study conducted a literature review and article search using the PubMed database. The search utilized specific keywords [obesity-induced inflammation and metabolic disorders and growth factors]. The article selection process followed the guidelines set by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. The process involved removing duplicate articles and further refining the selection to include studies published between 2015 and 2025, and those published in English. Book sections, studies involving animals, review articles, and conference proceedings were excluded. Data extraction encompassed a range of variables such as author names, article titles, publication years, study designs.
