Nasca Lab
The Epigenetics & System Neuroscience laboratory headed by Dr. Carla Nasca is working on an innovative model of epigenetic mechanisms of neuroplasticity to stress with a new angle on mitochondrial metabolism. Key to this framework is the pivotal mitochondrial metabolite L-acetyl-carnitine or LAC, which our lab discovered as a novel epigenetic modulator of glutamatergic function and a promising therapeutic target for clinical endophenotypes of depression – a prodrome to Alzheimer’s Disease. Our laboratory also uses computational approaches together with emerging technologies to isolate patient-derived exosomes for identifying in vivo neural mechanisms of main CNS diseases (mood and cognitive disorders) and potential biomarkers of the responses to antidepressant candidates (LAC), drugs (ketamine) and brain stimulation (TMS).
Research Interests
Dr. Nasca’s research led to the discovery of acetyl-L-carnitine (LAC) as a promising biological marker of depression and a modulator of brain plasticity – the ability of the brain to change and rewire. LAC is a metabolite found in the mitochondria, which is known as the powerhouse of the cell. Dr. Nasca demonstrated that LAC can turn on genes important for brain plasticity. This effect occurs primarily with genes related to the neurotransmitter, glutamate, in parts of the brain involved in emotion. In turn, administration of LAC can act as a rapid anti-depressant in mice exposed to chronic stress, a primary risk factor for depression. Dr. Nasca’s current investigation established a broader link between LAC and metabolic problems of depression such as insulin resistance – a condition in which organs have trouble using glucose, the body’s main source of fuel. The translational work in humans suggests that LAC is a biomarker of depression associated with childhood trauma and resistance to traditional antidepressants. These novel insights into fundamental mechanisms of the brain increases our basic understanding of brain-body communication and opens the possibility for novel, more effective therapies for metabolic problems and depression in a way different from traditional antidepressants.
