Florida Atlantic University Receives NIH Grant to Investigate Amphetamine Addiction

Strategic Insights -

Florida Atlantic University's associate professor of neuroscience Lucia Carvelli has received a $571,675 grant from the National Institutes of Health to advance critical research into how amphetamines affect brain function. The study aims to fill major gaps in understanding amphetamine's effects on the brain, which could lead to new therapies targeting substance use disorders and dopamine-related neurological conditions. Amphetamine and its derivatives are widely abused, resulting in over 32,000 deaths in the United States due to amphetamine-involved overdoses in 2021.

Key Takeaways:

  • The study will investigate how amphetamines affect brain function, focusing on the dopaminergic system, which regulates reward and motivation.
  • The research team will use genetically tractable model organisms, such as the microscopic roundworm Caenorhabditis elegans, to dissect the cellular pathways impacted by amphetamines.
  • The team will identify novel regulators of dopamine release during amphetamine exposure and genes that mediate amphetamine's effects independently of the traditional dopamine release pathway.
  • The study aims to uncover new biological targets that could lead to safer, more effective treatments for substance use disorders, including ADHD and addiction.
  • The research experience will provide valuable training opportunities for undergraduate students, who will gain hands-on experience in cutting-edge neuroscience research.
  • The project builds on previous work by Carvelli's lab, which discovered a dopamine-dependent behavior called Swip in C. elegans that is triggered by an excess of dopamine in the synaptic space.

Statistics:

  • The grant is worth $571,675.
  • Amphetamine and its derivatives are among the most widely abused drugs worldwide.
  • Over 32,000 deaths in the United States were attributed to amphetamine-involved overdoses in 2021.
  • The C. elegans model system has just 302 neurons, including eight dopaminergic neurons, making it a simplified yet powerful system for dissecting the cellular pathways impacted by amphetamines.
  • The Million Mutation Project genetic library contains well-documented mutations in C. elegans strains, which will be used to identify novel regulators of dopamine release during amphetamine exposure.
