STRUCTURAL NEUROSCIENCE OF SYNAPSE CONNECTIVITY

 



Welcome to the Ressl Lab.
We develop and employ tools to understand the structural basis of proteins at the synapse.

RESEARCH

Our research is in the emerging and fast-growing field of Structural Neuroscience. Structural Neuroscience reveals breakthrough insights into the structural basis of proteins critical to the form and function of the nervous system.

PROJECT AREAS

  • Synapse membrane proteins and organizers. Essential to the form and function of chemical synapses, these proteins - when broken or dysregulated - are associated with cognitive brain and neurodegenerative disorders - synaptopathies. Proteins seldom work alone. Therefore, our team works on selected proteins (GPCRs, channels, and secreted synapse-organizing proteins), showing that they form intricate protein complexes and networks at the synapse. We identify new synaptic protein-protein interactions and decipher their fundamental structure-function relationships to understand the basis of brain health and disease. We use multimodal and interdisciplinary approaches to generate spatial and temporal data. We collaborate with other experts (Martinelli lab, Lee lab) to develop comprehensive models of understanding behind synaptopathies.

  • Method development to study membrane proteins of the brain. The challenge of studying membrane proteins is rooted in their intrinsic dual hydrophobic-hydrophilic nature and compounded by the limited availability of membrane-mimetic tools. We are thrilled to collaborate with the brilliant Callmann group to employ our expertise and combine biochemistry, biophysics, soft materials science, and nanotechnology to develop highly innovative membrane-mimetic tools. Our tools will enable to study membrane proteins using multi-scale techniques that span across different system levels. This project will lead to greater interdisciplinary scientific advancements and faster progress in diagnostic and therapeutic developments.

  • Ion channels. We are excited to collaborate with the talented Goldschen-Ohm group on the structure-function of the pharmacologically so relevant Gamma-aminobutyric acid receptor.

SCIENTIST MEETS ARTIST COLLABORATIVE PROJECT

It all began with a walk in the woods, which led to an incredible opportunity to work with the amazing artist Jiangmei Wu. Together, we transformed a protein structure into a captivating interactive sculpture. Our sculpture “Light Harvest” had integrated sensors reacting with light spectrum and intensity to the observer's orientation and movement around the sculpture. This interactive experience was realized with the help of the very talented Kyle Overton. “Light Harvest” was exhibited nationally and internationally.
