This research explores the impact of acute changes in mitochondrial lipid composition on mitochondrial functions, aiming to inform new therapeutic strategies for mitochondrial-associated disorders.
The proposed research aims to elucidate the impact of dyslipidemia—abnormal lipid metabolism—on mitochondrial functions by focusing on the lipid composition of the outer mitochondrial membrane (OMM). This study hypothesizes that acute changes to the OMM lipid composition directly influence mitochondrial dynamics, energetics, and quality control processes. By advancing our understanding of how lipids regulate mitochondrial biology, this research could lead to the development of innovative therapeutic approaches targeting subcellular lipid metabolism to treat mitochondrial-associated disorders.
This study will employ advanced methodologies to alter organelle membrane lipid composition within live cells, particularly targeting the OMM. By rapidly remodeling lipids specifically within the OMM, the research will explore how local lipid composition affects mitochondrial morphology, respiratory function, proteostasis, selective mitophagy, and inter-organelle communication. The approach contrasts with previous studies that relied on long-term genetic alterations, providing a more direct assessment of lipid impacts on mitochondrial functions.
The research is currently at Technology Readiness Level 4, indicating that component and/or breadboard validation have been conducted in laboratory environments. Future efforts will focus on further experimental validation and the development of therapeutic interventions informed by these findings.
