UND pharmacologist to speak in biomedical science lecture series Keith Henry, assistant professor of pharmacology, physiology, and therapeutics, will give a seminar titled, "Understanding Molecular interactions: How Small Changes Make for Big Differences" at 1 p.m. Friday, Oct. 10, in Room 5510, Medical School. Dr. Henry's work focuses on a class of proteins called transporters -- proteins that help to move proteins, ions and biochemically active compounds in and out of cells -- and how these transporters are regulated in normal and diseased states. He will talk about the general nature of his work and focus some specific examples on his recent work with the serotonin transporter, and its larger implications to health and the scientific enterprise.
