Immunocytochemical Localization of TASK-3 Channels in Rat Motor Neurons

Abstract: Motor neurons are large cholinergic neurons located in the brain stem and spinal cord. In recent years, a functional role for TASK channels in cellular excitability and vulnerability to anesthetics of motor neurons has been described. Using a polyclonal monospecific antibody against the tandem pore domain K(+) channel (K2P channel) TWIK-related acid-sensitive K(+) channel (TASK-3), we analyzed the expression of the TASK-3 protein in motor systems of the rat CNS. Immunocytochemical staining showed strong TASK-3… Show more

“…TASK-3 channels are members of the K2P channel family that is sensitive to acid and inhalation anesthetics at clinically relevant concentrations and widely expressed in the rodent brain (Talley et al, 2001; Vega-Saenz de Miera et al, 2001; Aller et al, 2005; Aller and Wisden, 2008). At a subcellular level, TASK-3 channel are expressed in the somatodendritic regions of the neuron, much like Kv4 channels (Marinc et al, 2012). …”

“…Sabe-se que em diferentes patologias do sistema respiratório ocorre a redução do pH arterial e aumento da PaCO2 (ARAUJO et al, 2008;CABRAL;MUELLER, 2010;VENKATARAMAN et al, 2020). Além disso, canais de vazamento K2P, especificamente canais do tipo TASK-1 e TASK-3, são altamente expressos no DMV e também são sensíveis às alterações no pH extracelular (BAYLISS et al, 2001;BERG, 2004;MARINC et al, 2012;NIEMEYER et al, 2010;RAJAN et al, 2000). LIVINGSTON;BERGER, 1993;MORAES;MACHADO, 2015;SAH, 1992;SAH;MCLACHLAN, 1993;WANG;BIEGER;NEUMAN, 1991).…”

“…Ao verificarmos que a corrente de vazamento é principalmente mediada pelo íon K + , consideramos então a participação dos canais de vazamento K2p, da subfamília TASK que são expressos no sistema nervoso central (KANG;HAN;KIM, 2006;MEDHURST et al, 2001;TALLEY et al, 2001), principalmente TASK-1 e TASK-3 que são expressos no DMV (BAYLISS et al, 2001;MARINC et al, 2012), e que estes canais apresentam sensibilidade às alterações no pH extracelular (BROWN, 2000;NIEMEYER et al, 2010;RAJAN et al, 2000;SIROIS et al, 2000;TALLEY et al, 2000). Vale destacar que utilizamos aCSF em pH muito baixo (pH 6.9), para maximizar as respostas da condutância de vazamento e do potencial de membrana em repouso dos motoneurônios respiratórios do DMV.…”
