Recently, NOS activity has been demonstrated in several bacterial species, including notorious pathogens Bacillus anthracis and Staphylococcus aureus. Therefore, the influence of immunosuppressive drug leflunomide on inducible nitric oxide synthase (iNOS)-dependent NO production in rat astrocytes and macrophages was investigated. The nitric oxide synthase (NOS) inhibitor, NGmono-methyl-L-arginine (L-NMMA), blunted this effect only in LM3 cells while in LM2 cells the action of CARB was blocked by Nomega hydroxy-L-arginine (L-OH-Arg), which is known to inhibit the arginase pathway. Thus, phosphorylation of eNOS by Akt represents a novel Ca2+-independent regulatory mechanism for activation of eNOS. Inhibition of p38 MAPKalpha also blunted Akt activation in response to black tea polyphenols, suggesting that p38alpha MAPK is upstream of Akt in this pathway.
