Abstract
The autonomic innervation in the anterior chamber (AC) structures might play an efferent role in neural intraocular pressure (IOP) regulation, the center of which is thought to be located in the hypothalamus. In this study, we identified the efferent pathway from the hypothalamus to the autonomic innervation in the AC structures. Retrograde trans-multisynaptic pseudorabies virus (PRV) expressing green or red fluorescent protein, PRV531 and PRV724, was injected into the right and left AC of five rats, respectively; PRV531 was injected into the right AC of another five rats, and a non-trans-synaptic tracer, FAST Dil, was injected into the right AC of five rats as a control. Fluorescence signals in autonomic ganglia,the spinal cord and the central nervous system (CNS) were observed. Seven days after FAST Dil right AC injection, FAST Dil-labeled neurons were observed in the ipsilateral autonomic ganglia, including the superior cervical ganglion, pterygopalatine ganglion, and ciliary ganglion, but not in the CNS. Four and a half days after PRV531 injection into the right AC, PRV531-labeled neurons could be observed in the ipsilateral autonomic ganglia and bilateral hypothalamus nuclei, especially in the suprachiasmatic nucleus, paraventricular nucleus, dorsomedial hypothalamus, perifornical hypothalamus and ventral mammillary nucleus. Fluorescence signals of PRV531 mainly located in the ipsilateral autonomic preganglionic nuclei (Edinger-Westphal nucleus, superior salivatory nucleus and intermediolateral nucleus), but not in sensory trigeminal nuclei. Four and a half days after PRV531 right AC injection and PRV724 left AC injection, PRV531-labeled, PRV724-labeled, and double-labeled neurons could be observed in the above mentioned bilateral hypothalamus nuclei; but few contralateral infection-involving neurons (including double-labeled neurons) could be detected in the autonomic preganglionic nuclei. Our results indicate that there exist a both crossed and uncrossed hypothalamo-pre-parasympathetic and -pre-sympathetic tracts in the efferent pathways between the bilateral hypothalamic nuclei and the autonomic innervation of the bilateral AC.
