Cím:	Regional and developmental regulation of syntaphilin expression in the brain : a candidate molecular element of synaptic functional differentiation / Sunit Das, Judit Boczan, Claudia Gerwin, Philip B. Zald, Zu-Hang Sheng
Dátum:	2003

Megjegyzések:	The conserved nature of the basic machinery underlying synaptic function makes it necessary to search for other factors--structural and molecular--that could account for the tremendous diversity found among synapses even within a single neuron. Syntaphilin is a presynaptic membrane protein previously described as a molecular clamp that controls free syntaxin-1A and dynamin-1 availability, and thereby regulates synaptic vesicle exocytosis and endocytosis at the nerve terminal. In this study, we report our finding that syntaphilin expression is developmentally regulated, and show that syntaphilin is expressed most prominently in the mature rat brain, in areas that have been previously characterized to undergo synaptic plastic change. We also find that syntaphilin undergoes divergent subcellular targeting to the mitochondrial outer membrane and the synaptic plasma membrane, giving rise to two neuronal subpopulations of the protein that are modified in their relative enrichment with synaptic maturation and with the formation of cell contacts. Finally, we demonstrate that syntaphilin expression is initiated with induction of neuronal differentiation in PC12 cells. Given its biochemical and functional properties, the spatially and temporally limited nature of syntaphilin expression provides evidence that syntaphilin could be a molecular element of synaptic functional differentiation.

Cím:	Expression and distribution of vanilloid receptor 1 (TRPV1) in the adult rat brain / Toth, A., Boczan, J., Kedei, N., Lizanecz, E., Bagi, Z., Papp, Z., Edes, I., Csiba, L., Blumberg, P. M.

Megjegyzések:	The vanilloid receptor (TRPV1 or VR1) is a molecular integrator of various painful stimuli, including capsaicin, acid, and high temperature. It can also be activated by endogenous ligands, like the cannabinoid 1 receptor (CB1) agonist anandamide. TRPV1 is well characterized at the terminals of sensory nerves involved in the pain pathway. There is also evidence that TRPV1 is expressed in the brain but little is known about its function. Here, using commercially available specific antibodies to investigate the localization of TRPV1 in the brain of the rat, we report that TRPV1 was expressed in hippocampus, cortex, cerebellum, olfactory bulb, mesencephalon and hindbrain. Immunohistochemical analyses showed high expression in the cell bodies and dendrites of neurons in the hippocampus and in the cortex. To address the question of subcellular localization, immunoelectronmicroscopy was used. TRPV1-like staining was detected in the synapses (mostly, but not exclusively in post-synaptic dendritic spines), on the end feet of astrocytes and in pericytes. In summary, TRPV1 expression shows wide distribution in the brain of the rat, being found in astrocytes and pericytes as well as in neurons. Its localization is consistent with multiple functions within the central nervous system, including the regulation of brain vasculature.
