Neurite outgrowth and synaptogenesis

Dr. Lagenaur's research interests center on cell recognition events that are important in synapse formation and function. The laboratory is currently studying two cell adhesion molecules, SIRP and CD47 which bind to one another and are localized to sites of synaptic contact. Both molecules have signaling capabilities and may be involved in regulation of synaptic plasticity. The goal of the laboratory's research is to determine how SIRP and CD47 signaling modify synaptic function. Work in collaboration with Drs. Cui and Weber, Dept. of Bioengineering, explore the use of neural cell adhesion molecules to improve bio-compatibility of chronic neural implants. Trainees in Dr. Lagenaur's laboratory have the opportunity to learn a variety of molecular and cell biological techniques such as cell culture, video microscopy, in situ hybridization, and immunochemical techniques for investigating biochemistry of signal transduction molecules in the central nervous system.
