NOS2 and Sepsis: We have already observed that the inhibition of iNOS drives to a pre-dominance of sympathetic ANS (Castardo-de-Paula et al., 2017), however there are few data available on the relation between iNOS and sympathetic ANS in females in sepsis, being this the first observation of such factors in female Wistar rats, in the first hours of LPS endotoxemia.
