Figure 1. Attenuation of the hypoxic ventilatory response by disruption of vesicular release mechanisms in preBötC astrocytes
A, ventilatory responses of young and older (anaesthetized) piglets to hypoxia (6%) (modified with permission from Moss, RA. Respir Physiol (2000) 121, 185–197). B, summary data illustrating hypoxia‐induced changes in minute lung ventilation in carotid body intact and peripherally chemodenervated (10 weeks) conscious rats expressing CatCh (calcium translocating channel rhodopsin variant that was fused with EGFP and used as a control here) or TeLC bilaterally within astrocytes of the preBötC network. Ventilation measurements were obtained during the last 5 min of the 10 min hypoxia period. TeLC caused similar reductions in the HVR of intact and CB‐denervated rats (modified with permission from Angelova et al. 2015).
