    Medullary astrocytes mediate irregular breathing patterns generation in chronic heart failure through purinergic P2X7 receptor signalling
    (2022) Toledo, Camilo; Diaz-Jara, Esteban; Diaz, Hugo S.; Schwarz, Karla G.; Pereyra, Katherin, V; Las Heras, Alexandra; Rios-Gallardo, Angelica; Andrade, David C.; Moreira, Thiago; Takakura, Ana; Marcus, Noah J.; Del Rio, Rodrigo
    Background Breathing disorders (BD) (apnoeas/hypopneas, periodic breathing) are highly prevalent in chronic heart failure (CHF) and are associated with altered central respiratory control. Ample evidence identifies the retrotrapezoid nucleus (RTN) as an important chemosensitivity region for ventilatory control and generation of BD in CHF, however little is known about the cellular mechanisms underlying the RTN/BD relationship. Within the RTN, astrocyte-mediated purinergic signalling modulates respiration, but the potential contribution of RTN astrocytes to BD in CHF has not been explored.
