After completing undergraduate work in Chemistry and Biology at Lincoln University, Darrell Jackson received a Ph.D. in Pharmacology/Toxicology from Washington State University in 1990 at Pullman. Following postdoctoral positions at Massachusetts Institute of Technology, Boston University, and University of Washington, and faculty positions at Washington State University and Morehouse School of Medicine in Atlanta, he moved to The University of Montana as an Associate Professor in 2004.
Field of Study
Our studies have significant implications for linking dysfunctions in G-protein-coupled receptor (GPCR) signaling with numerous neurological disorders that includes Alzheimer's disease, Parkinson's disease, and stroke. A major focus in the laboratory is identifying and characterizing the mechanisms that regulate the endosomal sorting of internalized cell surface GPCRs in neurons. Sequestration of cell surface neurotransmitter receptors, such as GPCRs, is one mechanism utilized by neurons to terminate receptor signaling. The mechanism regulating endosomal sorting of internalized GPCRs in neurons remains unclear. A second focus in the laboratory involves elucidating the underlying mechanisms that mediate the polarize sorting of selective GPCRs in neurons to either dendritic or axonal compartments.
