Objective
The purpose of this project is a complex analysis of the molecular mechanisms underlying the regulation of neurotransmitter-activated ionic channels during ontogenetic and phylogenetic development of the nervous system. The study will be conducted on mammalian neurones in the central nervous system (hippocampal slices and tissue culture) and on invertebrate neurones (from the mollusks Aplysia and Lymnaea stagnalis).
Using a combination of patch-clamp recording techniques and laser scanning confocal microscope on neurons in hippocampal slices, the properties of ionic channels activated by glutamate and GABA during the first days of postnatal development will be investigated.
Using the calcium-sensitive fluorescent dyes (Indo-1 and Fluo-3) and the patch-clamp recording technique, simultaneous monitoring of neurotransmitter-activated ionic currents and intracellular Ca2+ concentration ([Ca2+]i in cultured hippocampal neurones as well as hippocampal slices of different ages will be conducted.
Using biochemical analysis of endogenous phosphorylation of proteins in homogenates of hippocampal slices and specific antibodies raised against synaptic proteins, the possible role of proteins specifically involved in synaptic transmission during the establishment of synaptic contacts and synaptic transmission during the maturation of the brain will be estimated.
