RESEARCH
Over the
years my research interest has evolved and is now focused on the molecular
basis of neurobehavioral changes using in-vitro and in-vivo systemsa,b.
The broad research area of my interest is in drug abuse and mental health.
1. Drug abuse research:
Cannabinoid researcha: The goal of this continuing research is to
unravel the mechanism of some cannabinoid induced behaviors. In order to
accomplish this goal, I use molecular techniques in combination with
stereotaxic approaches to determine the molecular events associated with
cannabinoid induced behavioral changesa,b,c,d. Specifically, we have
used cloning, gene expression and immunoblotting analysis to study cannabinoid
induced behaviors. This research is being extended to the use of cannabinoid
transgenic and inducible mutant mice in order to understand behavioral
alterations following cannabis use. As addiction may be to multiple substances,
where appropriate, other abused drugs are evaluated in the in-vivo and in-vitro
end pointse as well as interaction between cannabinoids and
vanilloid systems.
2. Mental health research:
Two strategies are involved. First is to extend the animal work to human
studies. Second is the use of animal models to study human neuropsychiatric
disorders like depression and anxiety. An example of the first program is to
understand the influence of gender and race on the effects of abused
substances, particularly cannabinoids. One such project is studying ethnic and gender
differences on cannabinoid receptors and the expression of their transcripts in
blood of human subjectsf. The long-term goal of the project is to
determine the role of cannabinoid receptors in different neuropsychiatric
conditions.
3. Animal models of neuropsychiatric disorders:
The use of animal models of depression and anxiety is related to both drug
abuse and mental health research. There may be a link between abused drugs and
anxiety and/or depression in terms of vulnerability to drug abuse, withdrawal
and craving reactions. My approach is to study the molecular basis of
neurobehavioral alterations using these animal models of neuropsychiatric
disordersa,b,c,d,e.
