New research study reveals how glutamate tRNA pieces contribute to brain aging and Alzheimers disease by hindering mitochondrial function. Research has shown that mitochondrial dysfunction is closely associated with brain aging and Alzheimers disease.Schematic representation of the regulative mechanisms of tRNA fragments in brain aging and Alzheimers illness. Additionally, lowering Glu-5 tsRNA-CTC can safeguard the aging brain from age-related flaws in mitochondrial cristae, glutamine metabolism, synaptic structure, and memory.Liu and his group shed light on the vital role of glutamate tRNA pieces in brain aging and Alzheimers disease, offering brand-new insights for delaying cognitive decrease.
