From Sequence to Dynamics to Function: Computational Design of Allostery and Ligand Selectivity in G-Protein Coupled Receptors

Mahdi Hijazi

The phenomenon of allostery, a general property in proteins that has been heralded as "the second secret of life" remains elusive to our understanding and even more challenging to incorporate into protein design. One example of allosteric proteins with gre ...

Interfacing aptamer-modified nanopipettes with neuronal media and ex vivo brain tissue

Nako Nakatsuka, Anna Burdina, Annina Stuber

Aptamer-functionalized biosensors exhibit high selectivity for monitoring neurotransmitters in complex environments. We translated nanoscale aptamer-modified nanopipette sensors to detect endogenous dopamine release in vitro and ex vivo. These sensors empl ...

Computational rewiring of allosteric pathways reprograms GPCR selective responses to ligands

Patrick Daniel Barth, Mahdi Hijazi, Aurélien Laurent Jean-Charles Oggier, Dániel Kéri

G-protein-coupled receptors (GPCRs) are the largest class of cell surface receptors and drug targets, and respond to a wide variety of chemical stimuli to activate diverse cellular functions. Understanding and predicting how ligand binding triggers a speci ...

A method for determining the presence of a molecule coupled to the cytoplasmic side of a cellular membrane is disclosed. The method is implemented in a microfluidic setting and is particularly suitable for determining the presence and/or the activity of a ...

2022

G protein-coupled receptors (GPCRs) are 7-transmembrane alpha-helical integral membrane proteins on which cells heavily rely to receive information regarding their external environment. These receptors are able to transfer information to intracellular down ...

EPFL2021

G protein-coupled receptors play essential roles in cellular processes such as neuronal signaling, vision, olfaction, tasting, and metabolism. As GPCRs are the most important drug targets, understanding their interactions with ligands is of utmost importan ...

AMER CHEMICAL SOC2020

Giant unilamellar lipid vesicles (GUVs) are widely used as model membrane systems and provide an excellent basis to construct artificial cells. To construct more sophisticated artificial cells, proteins-in particular membrane proteins-need to be incorporat ...

Mining the Potential of Label-Free Biosensors for In Vitro Antipsychotic Drug Screening

Sandro Carrara, Hatice Altug, Tugba Kilic, Maria Soler Aznar

The pharmaceutical industry is facing enormous challenges due to high drug attribution rates. For the past decades, novel methods have been developed for safety and efficacy testing, as well as for improving early development stages. In vitro screening met ...

A novel psychoanalytical approach: An electrochemical ligand-binding assay to screen antipsychotics

Sandro Carrara, Tugba Kilic

Schizophrenia treatment may see a paradigm shift due to development of new atypical antipsychotic drugs (APDs), with better tolerability due to more selective dopamine (DA) receptor blockade. Monitoring of these APD candidates in biological fluids is of gr ...
