Episodic stimulation of central chemoreceptor neurons elicits disordered breathing and autonomic dysfunction in volume overload heart failure.

Díaz HS, Andrade DC, Toledo C, Pereyra KV, Schwarz KG, Díaz-Jara E, Lucero C, Arce-Álvarez A, Schultz HD, Silva JN, Takakura AC, Moreira TS, Marcus NJ, Del Rio R (2020) Episodic stimulation of central chemoreceptor neurons elicits disordered breathing and autonomic dysfunction in volume overload heart failure. Am J Physiol Lung Cell Mol Physiol 318(1):L27-L40. doi: 10.1152/ajplung.00007.2019

Objective: To determine the role of the central chemoreflex in the development of respiratory and autonomic dysfunction in volume overload heart failure (HF).

Summary: Episodic hypercapnic stimulation triggers ventilatory plasticity and elicits cardiorespiratory abnormalities in HF that are largely dependent on retrotrapezoid nucleus (RTN) chemoreceptor neurons.

Usage: Bilateral injections of SSP-SAP, 0.6 ng/30 nL, into the RTN were administered to destroy chemoreceptor neurons.
