General description

Chemical structure: peptide

Biochem/physiol Actions

Inhibitor of human leukocyte elastase and proteinase 3, originally isolated from the skin of patients with psoriasis. May protect against certain autoimmune tissue damage. An elastase inhibitor which is an active fragment of elafin, as well as elafin itself, can also be found in bronchial carcinoma secretions.
Exhibits co-existent antimicrobial and antiproteolytic activities.1 Inhibits WAP-type four-disulfide core (WFDC) domain containing elastases. Antimicrobial spectrum: Gram-positive and Gram-negative bacteria.

Trappin-2/elafin is a novel innate immune factor that belongs to the serine protease inhibitor family and has known antibacterial, antifungal, and antiviral properties. In this study, we further investigated the anti-HIV activity of elafin using different cellular models and both

Type 1 diabetes is an autoimmune disease resulted from self-destruction of insulin-producing pancreatic β cells. However, the pathological pathways that trigger the autoimmune destruction remain poorly understood. Clinical studies have demonstrated close associations of neutrophils and neutrophil elastase (NE) with

High abundance proteins like protease inhibitors of plasma display a multitude of interactions in natural environments. Quantitative analysis of such interactions in vivo is essential to study diseases, but have not been forthcoming, as most methods cannot be directly applied

Elafin is an antimicrobial and anti-inflammatory protein. We hypothesize that elafin expression correlates with diabetes. Among non-diabetic and prediabetic groups, men have significantly higher serum elafin levels than women. Men with type 2 diabetes mellitus (T2DM) have significantly lower serum

The serine protease inhibitor, elafin, is a critical component of the epithelial barrier against neutrophil elastase (NE). Elafin is downregulated in the majority of breast cancer cell lines compared with normal human mammary epithelial cells (HMECs). Here, we evaluated the
