Description
Synapses are essential relay stations that confer information between cells. Synapses form between neurons or as in the case of the neuromuscular synapse (NMS) between a motor neuron and a muscle fiber. The NMS regulates every movement within our bodies including breathing and therefore is critical for survival. Our research focuses on the complex molecular intra- and intercellular interactions initiating NMS formation. In particular, we aim at identifying the signal transduction events and protein interactions responsible for NMS development. Our long-term goal is to understand the temporal and spatial mechanisms that lead to the formation of a mature and functional NMS.
