Abstract:
Nitric Oxide (NO) is internationally regarded as a signal molecule involved in several
functions in the respiratory tract under physiological and pathogenic conditions. Hydrogen Sulfide
(H2S) has also recently been recognized as a new gasotransmitter with a diverse range of functions
similar to those of NO.
Depending on their respective concentrations, both these molecules act synergistically or antagonistically
as signals or damage promoters. Nevertheless, available evidence shows that the complex
biological connections between NO and H2S involve multiple pathways and depend on the site of
action in the respiratory tract, as well as on experimental conditions. This review will provide an
update on these two gasotransmitters in physiological and pathological processes.
