Synaptic mitochondrial dysfunction and memory loss in aging

One of the most brain areas affected in aging is the hippocampus, crucial in learning and memory processes. My laboratory studies the changes of mitochondria of hippocampal neurons in aging, specifically those found in the synapse, areas of neuronal communication. Synaptic mitochondria are more vulnerable to damage than non-synaptic mitochondria. We are investigating the structural and functional differences in the synaptic mitochondria that explain this vulnerability and its contribution to age-related memory loss. We also study factors that promote mitochondrial dysfunction, including the accumulation of phosphorylated tau (Ser396-Ser404: PHF-1) in the mitochondria, a protein associated with microtubules that when phosphorylated loses its function. Another aspect that we explore is the potential anti-aging effect of molecules that enhance mitochondrial function. We used in vitro and in vivo models, including mouse primary hippocampal neuron, organotypic culture, and normally aged or senescence-accelerated prone mouse (SAMP8).
