Insights
Cytokines, adipokines, and hepatokines link chronic inflammation to insulin resistance and type 2 diabetes in children. These factors may predict metabolic syndrome and offer therapeutic targets.
Area of Science:
- Pediatric Endocrinology
- Metabolic Syndrome Research
- Inflammation and Diabetes
Background:
- Chronic inflammation, adipokines, and hepatokines are implicated in insulin resistance and beta cell failure.
- Understanding these factors in pediatric populations is crucial for metabolic health.
Purpose of the Study:
- To review current knowledge on the relationship between cytokines, inflammation, metabolic syndrome (MetS), and type 2 diabetes mellitus (T2DM) in children.
- To explore the potential predictive and therapeutic roles of these factors.
Main Methods:
- Review of existing literature on pediatric inflammation, metabolic syndrome, and type 2 diabetes.
- Analysis of pro-inflammatory and anti-inflammatory cytokines, adipokines, and hepatokines.
Main Results:
- Key pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) and anti-inflammatory cytokines (leptin, adiponectin) are associated with insulin resistance in children.
- Obesity alters levels of certain anti-inflammatory cytokines, indicating a resistance state.
- Specific cytokines (TNF-α, fetuin A, FGF-21) are altered in obese children with T2DM, suggesting a role in beta cell failure.
Conclusions:
- Cytokines, adipokines, and hepatokines are potential biomarkers for predicting MetS and T2DM development in children.
- These factors represent promising therapeutic targets for ameliorating insulin resistance and improving metabolic health.
Purpose Of Review:
Chronic inflammation, adipokines, and hepatokines have been identified as basis of insulin resistance and β cell failure in animal models. We present our current knowledge concerning the potential relationship between these cytokines, inflammation, metabolic syndrome (MetS), and type 2 diabetes mellitus (T2DM) in the pediatric population.
Recent Findings:
Pro-inflammatory cytokines related to insulin resistance and MetS in children are tumor necrosis factor-alpha (TNF-α), interleukin (IL)-6, IL-1β, interferon gamma, pigment epithelium-derived factor, chemerin, vaspin, and fetuin A. Anti-inflammatory cytokines associated with insulin resistance and MetS in children are leptin, adiponectin, omentin, fibroblast growth factor (FGF)-21, osteocalcin, and irisin. These anti-inflammatory cytokines are decreased (adiponectin, omentin, and osteocalcin) or increased (leptin, FGF-21, and irisin) in obesity suggesting a resistance state. TNF-α, fetuin A, and FGF-21 are altered in obese children with T2DM suggesting an involvement in β cell failure. These cytokines, adipokines, and hepatokines may be able to predict development of MetS and T2DM and have a potential therapeutic target ameliorating insulin resistance.
