HDL receptors are expressed in the brain parenchyma and along the periventricular zones. In situ hybridization of HDL receptors in the brain of adult zebrafish. The scheme provides the localization of the transversal section performed and the red square shows the regions where the high-magnification views were made. In situ hybridization in the medial zone of telencephalic area (Dm, A–E), the posterior part of the preoptic area (PPp, F–J), the ventral zone of the periventricular hypothalamus (Hv, K–O), around the lateral recess of the diencephalic ventricle (Lr, K–O), the periventricular pretectal nucleus ventral part (PPv, P–T), and the optic tectum (TeO, U–Y). Note that most HDL receptors are expressed in the brain parenchyma where neurons are localized and in periventricular zones where NSCs are localized. Scale bar = 50 μm.
