Systemic inflammatory and barrier function markers

Systemic inflammatory and barrier function markers represent a heterogeneous group of biological indicators used to assess the state of the immune system and the integrity of physiological barriers, such as the intestinal epithelium or the blood-brain barrier. Systemic inflammatory markers, including C-reactive protein (CRP) and various cytokines like Interleukin-6 (IL-6) and Tumor Necrosis Factor-alpha (TNF-alpha), provide insight into the body's overall inflammatory burden (Source: StatPearls, PMID: 30020619). Barrier function markers, such as zonulin or intestinal fatty acid-binding protein (I-FABP), indicate the degree of permeability or damage to cellular junctions that normally prevent the translocation of pathogens and toxins into the bloodstream (Source: Nature Reviews Gastroenterology & Hepatology, PMID: 26752199). These markers are critical in studying conditions like inflammatory bowel disease, metabolic syndrome, and systemic inflammatory response syndrome (Source: Frontiers in Immunology, PMID: 29971072). While they are essential for diagnostic and monitoring purposes, they are generally considered clinical endpoints or biomarkers rather than a single specific therapeutic target. However, individual components within this group, such as TNF-alpha or IL-6, are frequently targeted by biological therapies to manage chronic inflammation.
