Research Activity
In our laboratory, we want to understand how new experiences are transformed into stable and long-lasting memory and what goes awry in memory system that causes memory deficits. A search for the remedy against memory deficits is also an ongoing research activity. Several advanced behavioral, molecular and cellular techniques are used to dissect out the biological events that contribute to memory formation and memory deficits. We discovered that a gene corresponding to regulator of G protein signaling 14 of 414 amino acids (RGS14414) protein was able to induce memory enhancement and rescue episodic (recognition, spatial and temporal) memory deficits in rodent models. On the other hand, our laboratory is also engaged in other studies to identify potential targets for the treatment of memory deficits. Considering that memory is processed through interconnected brain circuits that are formed by the participation of distinct brain areas, and that memory deficits occur as a consequence of reduced activity within these circuits, we hypothesized that a revival in activity of these interconnected networks could restore memory. Our studies suggest that recovery of memory relies more heavily on the activation of brain circuits and the activation of one of the brain areas of interconnected brain circuits is sufficient to restore activity of these circuits and rescue memory deficits in memory-deficient animal models of aging and Alzheimer´s disease. This finding represents an important milestone in our understanding of how the function of a specific memory circuit can be restored. Furthermore, we found that activation of 14-3-3ζ-BDNF pathway induces synaptic structural plasticity and facilitates memory enhancement, and that this pathway is involved in the maintenance of synaptic vigor and the sustenance of memory functions. A sustained activity in the 14-3-3ζ–BDNF pathway could thus arrest the deterioration of neuronal networks and prevent memory deficits observed in aging and many neurological diseases
