Modulatory effects of N-acetyl-L-cysteine on human eosinophil apoptosis.
Eosinophils are oxidant-sensitive cells considered relevant in allergic inflammation. The present study aimed to examine the effects of the antioxidant N-acetyl-L-cysteine (NAC) on constitutive and cytokine-delayed apoptosis in human isolated eosinophils. Human eosinophils were purified from the blood of healthy donors by a magnetic separation system. Apoptosis and cellular glutathione were ass...
متن کاملEffects of N-acetyl-L-cysteine on Postoperative Intrabdominal Adhesion in a Large Animal Model
Objective- Mechanisms that decrease oxidative stress and enhance peritoneal fibrinolysis reduce adhesions. N-acetyl-L-cysteine (NAC) is an antioxidant whose effect on peritoneal fibrinolysis in large animal model has not been established. The aims of this study were to investigate the ability of NAC to decreased adhesion in stablished model of serosal trauma in sheep. Design- Expe...
متن کاملEffects of 4-hydroxynonenal and N-acetyl-L-cysteine on Myc-induced apoptosis.
Apoptosis has been described as programmed active cell death. Overexpression of the c-Myc gene has been shown to induce apoptosis in Rat1A/Myc-ER cells when combined with a growth blocking agent. In the present study, we tested whether 4-Hydroxynonenal (HNE) or N-acetyl-L-cysteine (LNAC) affect apoptotic death in serum deprived Rat1A/Myc-ER cells caused by the c-Myc protein. The incidence of ap...
متن کاملApoptosis of human primary B lymphocytes is inhibited by N-acetyl-L-cysteine.
Thiols are important molecules to control apoptosis. This study examined the effect of N-acetyl-L-cysteine (NAC) on in vitro spontaneous apoptosis of human tonsillar B lymphocytes (TBL). Results show that NAC inhibits TBL apoptosis and maintains their survival in vitro. The antiapoptotic action of NAC is progressively reduced when its addition to culture is delayed, is reversible, and is not bl...
متن کاملN-acetyl-L-cysteine and cysteine increase intracellular calcium concentration in human neutrophils
N-acetyl-L-cysteine (NAC) and cysteine have been implicated in a number of human neutrophils' functional responses. However, though Ca(2+) signaling is one of the key signalings contributing to the functional responses of human neutrophils, effects of NAC and cysteine on intracellular calcium concentration ([Ca(2+)]i) in human neutrophils have not been investigated yet. Thus, this study was car...
