Method for determining decrease in functions of hippocampus by using correlation between micro RNA and NMDA receptor, method for inhibiting decrease in functions, and method for screening for inhibitors of decrease in functions

[특허 요약] The present invention relates to a method for determining a decrease in the functions of the hippocampus by using the correlation between a micro RNA (miRNA) and an N-methyl-D-aspartate receptor (NMDAR), a method for inhibiting the decrease in the functions, and a method for screening for inhibitors of the decrease in the functions. The present invention confirms that miR-204, among miRNAs up-regulated in an aged hippocampus, decreases the expression of EphB2, by accurately targeting EphB2, which is an important regulatory receptor, resulting in a decrease in the neuronal surface expression of an NR1 subunit of an NMDAR in hippocampal nerves and a decrease in the density of dendrites, thereby having an effect of determining whether the functions of the hippocampus are decreased, by using the correlation between a miRNA and an NMDAR, and furthermore, has an effect of providing a method for inhibiting the decrease in the functions of the hippocampus, and a method for screening for inhibitors of the decrease in the functions.
