“…The majority of the peripheral chemoreceptor synapses are established in comissural NTS (cNTS) (41), in which L-glutamate plays an important role in the processing of peripheral chemoreflex responses (13,17,28). Moreover, the glutamatergic transmission within the NTS is required for the processing of baroreflexes (37) and Hering-Breuer (9) reflex responses, and microinjections of agonists (6) or antagonists (11,17) of its receptors evoke dramatic changes in the respiratory pattern and its coupling with sympathetic activity.…”

“…Concentrações mais elevadas de PPADS podem certamente antagonizar a transmissão glutamatérgica . No entanto, a dose de PPADS utilizada no presente estudo (5 mM) foi escolhida com base na literatura e a partir de estudos anteriores de nosso grupo (DE PAULA et al, 2004; não altera a resposta respiratória basal desempenhada pelo glutamato (BRACCIALLI et al, 2008). No entanto, não se pode descartar uma interação de glutamato e ATP na modulação da respiração e, portanto, futuros estudos são necessários para melhor avaliar a integração entre ambos neurotransmissores.…”

“…Nossos resultados corroboram com estudos em camundongos knockout para os receptores P2X 2 , que mostraram uma depressão respiratória durante hipóxia -MENDONCA et al, 2009;ALVARES et al, 2014;BRACCIALLI et al, 2008;BRAGA et al, 2007; NURSE, 2014;ZHANG et al, 2012).…”
