Research

Work in my laboratory involves the development of cellular assays for studying biologically active compounds such as natural products, drugs and hormones.  Delta-9-tetrahydrocannibinol (THC) and cannabidiol (CBD) are the two major cannabinoids found in marijuana (cannabis sativa).  To date, invcannabinoidsestigators have isolated over one hundred chemically distinct cannabinoids from marijuana.  It is anticipated that these cannabinoids and related compounds will be useful for treating anxiety, pain, inflammation and other disorders.

The figure to the right shows the structures of THC (top) and CBD (bottom).

In one project, immortalized neuronal cell lines are stably transfected with cannabinoid CB1 receptors using recombinant lentiviral vectors.  The effects of THC and CBD on the activation of G protein-gated inward rectifier K+ (GIRK) channels are then determined using a membrane potential-sensitive fluorescent dye assay.  These results are compared with the ability of the cannabinoids to inhibit adenylyl cyclase and to stimulate the recruitment of β-arrestin to the plasma membrane.
