Abstract: Retrotransposons, operating though human-specific neurological pathways, can contribute to environment, lifestyle, and/or age-related neurodegeneration by disrupting functional mitochondrial populations within neurons. The mitochondrial disruption can occur through a number of retrotransposon-induced mechanisms that can influence the efficient and accurate transcription and/or translation of mitochondrial genes encoded in the nuclear genome, operating primarily through epigenetic processes. Alu element-related conformational changes (both subtle and major) of the outer and inner mitochondrial membrane pores can restrict or prevent the normal translocation of proteins (i.e., TOMM and TIMM complexes), ultimately contributing to mitochondrial stress, mitophagy, inflammation, and neuron and glial cell death.
