Lauren Stein, a graduate student in the Yosten/Samson lab, received her doctorate at the SLU 2016 Graduate Programs commencement exercises May 12th. In April Dr. Stein received the Research Recognition Award from the Endocrinology and Metabolism Section of the American Physiological Society for her work identifying the receptor of the novel peptide hormone, Phoenixin, which was discovered by Drs. Yosten and Samson in 2013.

Dr. Stein has accepted an NIH funded postdoctoral fellowship in the Department of Psychiatry and the Translational Neurosciences Program at the Perlman School of Medicine, University of Pennsylvania. Dr. Stein will be continuing her studies on  the neuroendocrinology of energy balance in the laboratory of Dr. Matthew Hayes.
Willis K. Samson Ph.D. D.Sc. has been elected by the membership of the American Physiological Society to serve on its governing Council. Click here to read more.

RESEARCH SUMMARY

Our laboratory investigates the ability of peptides, regulatory proteins, and related substances to cross the blood-brain barrier (BBB). The ability of these substances to cross the BBB forms the basis for a humoral mediation of interactions between the central nervous system and the peripheral tissues. The applications of this premise are broad and our laboratory uses a variety of in vivo, in situ, and in vitro models to investigate various aspects of this field.

    Examples of currently active programs are:

     

  1. The role of peptide transport system (PTS)-1, a saturable system that transports methionine enkephalin (ME) from blood to brain, in regulating brain ME levels in alcohol dependence and withdrawal.
  2. The role that cytokine transport across the BBB plays in the neuroimmune axis.
  3. The role that the BBB plays through control of the exchange of leptin, insulin, pancreatic polypeptide and other feeding hormones in the regulation of body weight, appetite, and feeding behaviors.
  4. The mechanism used by the AIDS virus to enter and exit the central nervous system.
  5. The pathophysiology of prion penetration of the BBB.
  6. Alterations of neurotrophin and cytokine transport systems located at the BBB with various types of neurological injury including spinal cord trauma, animal models of multiple sclerosis, and brain ischemia.

Numerous other active projects relate to the pathophysiologic mechanisms of altered BBB function and the role that those alterations play in disease and health.
