Annexins constitute a family of calcium-dependent membrane-binding proteins and can be classified into two groups, depending on the length of the N-terminal domain unique for each individual annexin. The N-terminal domain of annexin A1 can adopt an alpha-helical conformation and has been implicated in mediating the membrane aggregation behavior of this protein. Although the calcium-independent ...
Inflammatory response is a kind of nonspecific immune response, with the central link of vascular response, which is mainly manifested by changes in neutrophils and vascular endothelial cells. In recent years, the in vivo and in vitro role of intravenous anesthetic propofol in inhibiting inflammatory response has been attracting more and more attention, but the anti-inflammatory mechanisms of p...
annexin a1 یک پروتئین 37 کیلو دالتونی با برخی تاثیرات ضد التهابی است. این پروتئین عضو پروتئین های خانواده annexins است که در سرکوب برخی از مسیرهای سیگنالی در گیر در التهاب کمک می کند. این پروتئین با مهار cpla2 از تولید آراشیدونیک اسید که سوبسترای آنزیم های لیپو اکسیزناژ و سیکلو اکسیژناژ است جلوگیری کرده و مانع تولید گونه های فعال اکسیژن ناشی از فعالیت این آنزیم ها می شود. همچنین در برخی منابع پ...
The immunosuppressive effects of apoptotic cells involve inhibition of pro-inflammatory cytokine release and establishment of an anti-inflammatory cytokine profile, thus limiting the degree of inflammation and promoting resolution. We report here that this is in part mediated by the release of the anti-inflammatory mediator annexin A1 from apoptotic cells and the functional activation of annexi...
Annexin A1 is a member of a phospholipid and calcium binding family of proteins; it is involved in anti-inflammation and in the regulation of differentiation, proliferation, and apoptosis. Here, we show the existence of a functional binding site for the tumor suppressor p53 near the proximal CCAAT box and the fact that the basal expression of annexin A1 in human colon adenocarcinoma cells is dr...
OBJECTIVE To examine the expression pattern of annexin A1 in normal and chronically inflamed nasal mucosa to investigate its possible role in nasal inflammation. DESIGN Immunohistochemical analysis. SUBJECTS Samples of middle turbinates from 5 healthy subjects and 5 patients with perennial rhinitis, and samples of nasal polyps from 7 patients. INTERVENTIONS Annexin A1 expression was exami...
The engulfment of apoptotic cells is of crucial importance for tissue homeostasis in multicellular organisms. A failure of this process results in secondary necrosis triggering proinflammatory cytokine production and autoimmune disease. In the present study, we investigated the role of annexin A1, an intracellular protein that has been implicated in the efficient removal of apoptotic cells. Con...
Evaluation of CRRT effects on pyemic secondary AKI by serum cartilage glycoprotein 39 and Annexin A1
The aim of the present study was to examine the effects of continuous renal replacement therapy (CRRT) on pyemic secondary acute kidney injury (AKI) by serum cartilage glycoprotein 39 (YKL-40) and Annexin A1. From October, 2013 to October, 2015, 45 pyemic secondary AKI cases and 40 pyemic non-secondary AKI cases were selected for the present study. There were also 35 cases of physical examinati...
Annexins A1 and A2 are proteins known to function in the stress response, dampening inflammatory responses and mediating fibrinolysis. We found, in healthy cattle recently arrived to a feedlot, that lower levels of these proteins correlated with later development of pneumonia. Here we determine the localization of annexin A1 and A2 proteins in the respiratory tract and in leukocytes, in healthy...
