Supplementary information

Secretory leukocyte protease inhibitor (SLPI) also known as antileukoproteinase and neutrophil elastase inhibitor is a protein with a molecular mass of approximately 12 kDa. SLPI is found mainly in epithelial tissues and is expressed in locations such as the respiratory tract skin and cervix. Mechanically SLPI functions as a serine protease inhibitor binding to and neutralizing enzymes like neutrophil elastase cathepsin G and trypsin which helps to limit tissue damage during inflammation.
Biological function summary

SLPI serves as a protector of epithelial surfaces from proteolytic degradation and acts as an anti-inflammatory agent. It displays broad-spectrum antimicrobial properties providing protection against bacterial and viral infections. Although SLPI is not part of a complex itself its interactions with extracellular matrix proteins help modulate wound healing processes and maintain tissue integrity.

Pathways

SLPI participates in the innate immune response and inflammation regulation pathways. It interacts within pathways that involve the complement cascade and kallikrein-kinin system helping to regulate inflammation and modulate immune responses. During these processes SLPI is related to proteins such as alpha-1-antitrypsin in its role as a protease inhibitor contributing to the regulation of protease activity and inflammatory responses.

SLPI is implicated in conditions such as chronic obstructive pulmonary disease (COPD) and cystic fibrosis where excessive protease activity leads to tissue damage. In these diseases SLPI shows a protective role against lung tissue degradation. SLPI is also associated with the progression of certain cancers like ovarian cancer where its overexpression may support tumor growth and metastasis. In these contexts SLPI relates to other protease inhibitors such as tissue inhibitors of metalloproteinases (TIMPs) due to their shared function in regulating protease activity and tissue remodeling.

General info

Function

Acid-stable proteinase inhibitor with strong affinities for trypsin, chymotrypsin, elastase, and cathepsin G (PubMed : 10702419, PubMed : 2039600, PubMed : 2110563, PubMed : 24121345, PubMed : 3462719, PubMed : 3533531). Modulates the inflammatory and immune responses after bacterial infection, and after infection by the intracellular parasite L.major. Down-regulates responses to bacterial lipopolysaccharide (LPS) (By similarity). Plays a role in regulating the activation of NF-kappa-B and inflammatory responses (PubMed : 10702419, PubMed : 24352879). Has antimicrobial activity against mycobacteria, but not against salmonella. Contributes to normal resistance against infection by M.tuberculosis. Required for normal resistance to infection by L.major. Required for normal wound healing, probably by preventing tissue damage by limiting protease activity (By similarity). Together with ELANE, required for normal differentiation and proliferation of bone marrow myeloid cells (PubMed : 24352879).
