Troy Rohn graduated in 1990 from the University of California at Davis with a B.S. in Physiology. He received his Ph.D. in Pharmacology from the University of Washington , Seattle in 1994. His interests include the role of apoptosis in neurodegenerative diseases. Dr. Rohn had several Postdoctoral stints including two plus years living in Paris , France , one year at Montana State University in Bozeman , Montana , and two years at UC Irvine at the Institute of Brain Aging and Dementia under the direction of Dr. Carl Cotman. Dr. Rohn continues to collaborate extensively with UC Irvine and in addition with Dr. Eliezer Masliah at UC San Diego. He has obtained extramural funding continuously since his arrival at BSU including grants from NIH, AFAR and AHAF.


BIOL442/542: This is a molecular neurobiology course for undergraduate and graduate-students. Topics covered are all aspects of neuronal function at the molecular level. A discussion of several neurodegenerative diseases including Parkinson’s, Alzheimer’s, and Schizophrenia are a few of diseases covered. BIOL 431/531: This is a general pharmacology course for undergraduate and graduate-students. Topics include the pharmacokinetics and pharmacodynamics. All major drug classes are covered in this course.
  • Both courses are taught in the fall semesters
BIOL 100: This is a non-majors course covering all aspects of biology. A two-hour weekly lab reinforces concepts taught in lecture. I also teach the electronic course for this class during spring semesters. BIOL 301: A cell biology course that represents a core requirement for all biology majors.  This course will be team taught with Dr. Cheryl Jorcyk starting in the spring semester of 2012.


The primary focus of my laboratory is involved in the research involving neurodegenerative diseases including to a large extent, Alzheimer’s disease (AD). During the progression of Alzheimer’s disease, many neurons die particularly in the area of the hippocampus. Because the hippocampus is an area of the brain involved in memory, AD is primary a disease where afflicted individuals lose their capacity for memory. Currently, we are investigating whether caspase-cleavage of APOE4 underlies its pathogenesis in AD. The APOE4 allele, if inherited greatly increases the risk of AD, but how it contributes to disease progression is not known. We believe this protein may be susceptible to proteolytic cleavage by proteases and this inactivates the ability of this protein to function properly in the brain. This could contribute to disease progression by allowing for the accumulation of the toxic protein, beta-amyloid, that is normally removed from the brain, in part by functional APOE4. My lab has recently been awarded an NIH grant to investigate this hypothesis. Our lab also has an interest in other neurodegenerative diseases including Parkinson’s, Pick’s, frontal temporal dementia and vascular dementia.
