Adenosine A 1 receptor distribution in the nucleus tractus solitarii of normotensive and spontaneously hypertensive rats

Abstract: Adenosine acts at many sites to modulate neuronal activity. The nucleus tractus solitarii (NTS) is a major brain site in cardiovascular control. The present study was undertaken for a detailed analysis of the distribution of A(1) adenosine receptor (A(1)R) in the NTS of spontaneously hypertensive rats (SHR) and Wistar Kyoto (WKY), using in vitro autoradiography with [(3)H]DPCPX. The density of [(3)H]DPCPX in the whole NTS decreased according to the rostral-caudal levels. This high level of [(3)H]DPCPX binding … Show more

“…[19][20][21] High-density oligoarrays allow the simultaneous measurement of global gene expression levels and is a valuable tool to study pathologies associated to the central nervous system. [22][23][24] In this study, we aimed to evaluate the effects of nicotine exposure on gene expression of cultured neurons and glia from pons and medulla oblongata of newborn SHR and WKY rats using whole-genome oligoarrays.…”

“…Estes resultados estão de acordo com os apresentados por Phillis e colaboradores (1997) os quais sugeriram uma distribuição heterogênea dos receptores de adenosina dentro do NTS. Estudos anteriores de nosso laboratório também demonstraram a existência de populações separadas de receptores A1 de adenosina dentro do NTS de ratos adultos (Carrettiero & Fior-Chadi, 2004), as quais seriam responsáveis por mediar respostas cardiovasculares diferenciadas (Scislo & O'Leary, 2002).…”

“…2B). Este resultado concorda com outros estudos na literatura, os quais reportam altos níveis de receptores A1 de adenosina no NTS de ratos SHR com relação a WKY (Carrettiero & Fior-Chadi, 2004;Matias et al, 1993). Além disso, defeitos funcionais dos receptores A1 de adenosina parecem estar relacionados com desenvolvimento da hipertensão no modelo SHR .…”
