Brain cell metabolic rate increase

Brain cell metabolic rate increase is a physiological process rather than a specific molecular target. It represents an elevation in the energy consumption of neurons and glia, typically quantified by the cerebral metabolic rate of glucose (CMRglc) or oxygen (CMRO2) (StatPearls, NBK554408). This state is often monitored in clinical settings using imaging techniques such as FDG-PET or functional MRI (RadioGraphics, 10.1148/rg.315105151). While not a single protein, the process is mediated by the collective activity of molecular entities including the Na+/K+-ATPase pump, mitochondrial respiratory chain complexes, and various neurotransmitter transporters (PubMed, 22613581). Therapeutic strategies aimed at increasing brain metabolic rate are primarily focused on addressing the hypometabolism associated with neurodegenerative disorders like Alzheimer's disease or enhancing cognitive performance (Frontiers in Aging Neuroscience, 10.3389/fnagi.2019.00204). However, pharmaceutical induction of high metabolic rates can pose risks of oxidative damage and metabolic stress to the central nervous system (Journal of Neuroscience Research, 10.1002/jnr.24077).

Increased metabolic rate is achieved through the antagonism of inhibitory receptors (e.g., adenosine), the stimulation of neurotransmitter release (e.g., dopamine, norepinephrine), or the direct uncoupling of mitochondrial oxidative phosphorylation.
