Are single nucleotide polymorphisms in the NOS2 and NOS3 genes associated with exhaled nitric oxide?
These results suggest that NOS2 is the major NOS gene determining variability in exhaled nitric oxide in the healthy adult population, while NOS3 may play a more important role in asthmatic adults.
TLR2, which traditionally associated with innate immunity, might also promote Th17 cells response in HBV infection. The function of TLRs in regulation of adaptive immune response in HBV infection, which might play an important role in persistent HBV infection.
