  • 功能：
    Neutrophil serine protease inhibitor that plays an essential role in the regulation of the innate immune response, inflammation and cellular homeostasis. Acts primarily to protect the cell from proteases released in the cytoplasm during stress or infection. These proteases are important in killing microbes but when released from granules, these potent enzymes also destroy host proteins and contribute to mortality. Regulates the activity of the neutrophil proteases elastase, cathepsin G, proteinase-3, chymase, chymotrypsin, and kallikrein-3. Acts also as a potent intracellular inhibitor of GZMH by directly blocking its proteolytic activity. During inflammation, limits the activity of inflammatory caspases CASP1, CASP4 and CASP5 by suppressing their caspase-recruitment domain (CARD) oligomerization and enzymatic activation. When secreted, promotes the proliferation of beta-cells via its protease inhibitory function.

    1. The expression of SERPINB1 was approximately 2-fold higher in apical periodontitis. SERPINB1 expression was noted in neutrophils and epithelial cells. PMID: 28673495
    2. SERPINB1 decreased inflammation, ameliorated oxidative stress in the lung, and attenuated acute lung injury in rats with orthotopic autologous liver transplantation by activating HO-1 and it does so through STAT3 PMID: 28427999
    3. a relatively low Serpinb1a protein threshold in neutrophils that is required for sustained survival PMID: 27107834
    4. SERPINB1 expression is significantly upregulated in human masticatory mucosa during wound healing PMID: 28005267
    5. Data show that high serpin B1 protein (SERPINB1) gene expression was associated with favorable tumor response and prolonged survival under cisplatin-based chemotherapy. PMID: 26799424
    6. Data show that oropharyngeal squamous cell carcinomas (OPSCCs) express granzyme inhibitors SERPINB1, SERPINB4 and SERPINB9 for cytotoxicity and the expression was not different between human papillomavirus (HPV)-positive and HPV-negative tumors. PMID: 26993499
    7. Pediatric CNS-PNETs evade immune recognition by downregulating cell surface MHC-I and CD1d expression. Intriguingly, expression of SERPINB9, SERPINB1, and SERPINB4 is acquired during tumorigenesis in 29%, 29%, and 57% of the tumors PMID: 26963506
    8. is not expressed in neutrophils of both sulfur mustard-exposed and chronic obstructive pulmonary disease patients PMID: 24852194
    9. Data suggest that serine protease inhibitor (SERPIN) B1 negatively regulates glioma cell migration and invasion probably by abrogating the expression of matrix metalloproteinase-2 and the activation of focal adhesion kinase. PMID: 24968089
    10. Decreased expression of SERPINB1 correlates with tumor invasion and poor prognosis in hepatocellular carcinoma. PMID: 24105272
    11. Apoptosis-inducing factor and leukocyte elastase inhibitor derived DNase II interact and can cooperate to induce cell death. PMID: 23673989
    12. Upon reactive center loop cleavage at Phe-343,SERPINB1 covalently complexes with GzmH. SERPINB1 overexpression suppresses GzmH- or LAK cell-mediated cytotoxicity. Crystal structures show possible conformational changes in GzmH for the suicide inhibition. PMID: 23269243
    13. In the resting state during human neutrophil extracellar trap generation, SerpinB1 is exclusively in the cytoplasm, consistent with the current understanding of clade B serpins, and it may migrate and regulate events in the cell nucleus. PMID: 23002442
    14. These results suggest that serpin B1 may be a novel marker of active ulcerative colitis and may play an important role in the pathogenesis of inflammatory bowel disease. PMID: 22421620
    15. serpinB1 sustains a healthy neutrophil reserve that is required in acute immune responses. PMID: 21248149
    16. The findings define an innate role for SerpinB1 in cystic fibrosis airways. PMID: 20817705
    17. M/NEI is a dual specificity inhibitor with two adjacent reactive sites that support rapid efficient inhibitory reactions with cellular proteases, including the three neutrophil granule proteases. PMID: 11747453
