| Gene Target | Biological Function | Application as a Biomarker |
|---|---|---|
| elastase, neutrophil expressed (ELANE) | ELANE encodes neutrophil elastase, a serine protease predominantly expressed in neutrophil granulocytes. Neutrophil elastase is stored in azurophilic granules and released during degranulation in response to infection or inflammation. Its primary function is to degrade a broad spectrum of extracellular matrix proteins, including elastin, collagen, and fibronectin, facilitating neutrophil migration through tissues and contributing to the destruction of engulfed pathogens. ELANE also participates in the regulation of inflammatory responses and tissue remodeling. Mutations in ELANE are associated with congenital neutropenia syndromes, underscoring its role in neutrophil function and hematopoiesis. | ELANE (neutrophil elastase) has been studied as a biomarker in various clinical contexts. Elevated levels of neutrophil elastase in biological fluids, such as plasma, serum, sputum, or bronchoalveolar lavage, have been associated with conditions characterized by increased neutrophil activation and tissue inflammation, including acute and chronic lung diseases (e.g., cystic fibrosis, chronic obstructive pulmonary disease), sepsis, and certain autoimmune disorders. Measurement of neutrophil elastase activity or concentration can provide information regarding the degree of neutrophil-driven inflammation or tissue injury. Additionally, genetic analysis of ELANE is used in the diagnostic evaluation of congenital neutropenia syndromes. |
| prolyl endopeptidase (PREP) | Prolyl endopeptidase (PREP), also known as prolyl oligopeptidase, is a serine protease that specifically cleaves peptide bonds at the carboxyl side of proline residues in oligopeptides, typically those shorter than 30 amino acids. PREP is widely expressed in various tissues, with particularly high levels in the brain. It is involved in the post-translational processing of neuropeptides and peptide hormones, thereby influencing signaling pathways related to cognition, mood, and neuroendocrine functions. PREP has been implicated in the regulation of neuropeptide activity, including substance P, vasopressin, and oxytocin, among others. Its enzymatic activity contributes to the modulation of synaptic transmission and neuronal signaling. | PREP has been studied as a potential biomarker in several neurological and psychiatric conditions, including neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease. Altered PREP activity or expression levels have been observed in brain tissue, cerebrospinal fluid, and peripheral blood in these contexts. Changes in PREP have also been investigated in relation to liver disease and certain cancers. Measurement of PREP activity or concentration is utilized in research to assess disease-associated changes and to explore its role in disease mechanisms. |
| tumor necrosis factor (TNF) | Tumor necrosis factor (TNF) is a pro-inflammatory cytokine primarily produced by activated macrophages, as well as other immune cells such as T lymphocytes and natural killer cells. TNF plays a central role in mediating inflammation and immune responses. It exerts its effects by binding to TNF receptors (TNFR1 and TNFR2) on various cell types, triggering signaling pathways that can lead to cell survival, apoptosis, or necrosis. TNF is involved in the regulation of immune cell activation, fever induction, and the acute phase response. It also contributes to the pathogenesis of various inflammatory and autoimmune diseases through its ability to promote leukocyte recruitment, cytokine production, and vascular permeability. | TNF levels in blood, tissues, or other biological fluids have been measured as an indicator of inflammatory activity in a range of clinical contexts. Elevated TNF concentrations have been associated with autoimmune diseases such as rheumatoid arthritis, inflammatory bowel disease, and psoriasis, as well as with infectious diseases and sepsis. TNF is also monitored in research and clinical studies evaluating the efficacy of anti-TNF therapies. Its quantification can assist in assessing disease activity, monitoring therapeutic responses, and investigating the underlying mechanisms of inflammation. |
