WebFeb 23, 2005 · The remaining portion of the molecule, cleaved HK, is designated cleaved high-molecular-weight kininogen or HKa. While BK has been intensively studied, the physiological implication of the generation of HKa is not clear. Recent studies have revealed that HKa inhibits angiogenesis while BK promotes angiogenesis. These findings … WebAug 10, 2006 · Objective— Plasma high-molecular-weight kininogen (HK) is cleaved in inflammatory diseases by kallikrein to HKa with release of bradykinin (BK). We postulated a direct link between HKa and cytokine/chemokine release. Methods and Results— HKa, but not BK, releases cytokines tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and …
WebJul 1, 1981 · Human high molecular weight (HMW) kininogen is a single chain with a molecular weight of 120,000 and is cleaved by plasma kallikrein sequentially into a nicked kininogen, an intermediate kinin-free protein (KFP-I), and a stable KFP-II. Here we report a study into the process of cleavage of human HMW kininogen by human salivary kallikrein. WebJan 15, 2010 · High molecular weight kininogen (HK) is a 120 kDa single-chain glycoprotein comprising 6 domains (designated as D1–D6) with a concentration in human plasma of ∼670 nM. Proteolytic cleavage of HK by kallikrein results in release of the nonapeptide bradykinin from D4.
