Neuronal and mitochondrial phospholipid membranes

Neuronal and mitochondrial phospholipid membranes are critical structural and functional components of the nervous system, providing the scaffold for signal transduction and energy production. These membranes are composed of a complex bilayer of phospholipids, cholesterol, and proteins that maintain cellular homeostasis and facilitate communication between neurons (Escribá et al., 2015, J. Cell. Mol. Med.). In many neurodegenerative and mitochondrial disorders, the composition and fluidity of these membranes are compromised, leading to impaired mitochondrial function, increased oxidative stress, and eventual cell death (Sabbah, 2016, PubMed). Therapeutic strategies, often referred to as membrane lipid therapy or melitherapy, aim to restore the healthy lipid architecture of these membranes to improve neuronal survival and metabolic efficiency (Pizcueta et al., 2020, Neurotherapeutics). Drugs targeting these structures, such as elamipretide, often work by stabilizing the lipid bilayer, specifically interacting with phospholipids like cardiolipin to enhance mitochondrial bioenergetics. By protecting the integrity of these membranes, these interventions seek to mitigate the progression of diseases like Alzheimer's and X-linked adrenoleukodystrophy.
