靶點詳情

  • 最新研究進展：
    CHI3L1（也稱為YKL-40）是一種由人類chitinase 3-like 1基因編碼的蛋白質。CHI3L1在炎癥和纖維化反應中發揮重要作用。最近的研究表明，CHI3L1與多種疾病的發病機制有關，如關節炎、哮喘、慢性阻塞性肺疾病、肝病和癌癥等。此外，CHI3L1在心臟病和腦卒中等心腦血管疾病中的潛在作用也被越來越多的研究所關注。
     
  • 功能：
    Carbohydrate-binding lectin with a preference for chitin. Has no chitinase activity. May play a role in tissue remodeling and in the capacity of cells to respond to and cope with changes in their environment. Plays a role in T-helper cell type 2 (Th2) inflammatory response and IL-13-induced inflammation, regulating allergen sensitization, inflammatory cell apoptosis, dendritic cell accumulation and M2 macrophage differentiation. Facilitates invasion of pathogenic enteric bacteria into colonic mucosa and lymphoid organs. Mediates activation of AKT1 signaling pathway and subsequent IL8 production in colonic epithelial cells. Regulates antibacterial responses in lung by contributing to macrophage bacterial killing, controlling bacterial dissemination and augmenting host tolerance. Also regulates hyperoxia-induced injury, inflammation and epithelial apoptosis in lung.
