2. 1. Neurosteroids Induce Allosteric Effects on the NMDA Receptor : Nanomolar Concentrations of Neurosteroids Exert Non-Genomic Effects on the NMDA Receptor Complex

   Author : Tobias Johansson; Fred Nyberg; Pierre Le Grevès; Elisabeth Hansson; Uppsala universitet; []
   Keywords : Pharmaceutical pharmacology; Pharmacology; neurosteroids; NMDA receptor; NR2B subunit; ifenprodil; sigma receptor; anabolic androgenic steroids; allosteric modulation; non-genomic; Farmaceutisk farmakologi;

   Abstract : The neurosteroids constitute a group of powerful hormones synthesized and acting in the central nervous system. They participate in a number of important central processes, such as memory and learning, mood and neuroprotection. READ MORE

4. 2. Modulation of Receptor Signaling and Functional Selectivity in Neutrophils

   Author : Michael Gabl; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophils; G-protein coupled receptors; reactive oxygen species; ligands; functional selectivity; allosteric modulation;

   Abstract : Neutrophils are important effector cells of the innate immune system and in the regulation of inflammation. Many of their functions, such as chemotactic migration, secretion of granule constituents and activation of the oxygen radical-producing NADPH-oxidase, are regulated by cell surface receptors.

5. 3. Structure-based Virtual Screening for Ligands of G Protein-coupled Receptors : Design of Allosteric and Dual-Target Modulators

   Author : Stefanie Kampen; Jens Carlsson; Peter Kolb; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; G protein-coupled receptors; Polypharmacology; Molecular Docking; Structure-based Drug Design; Parkinson’s Disease; Virtual Screening; Allosteric Modulators; Bioinformatics; Bioinformatik;

   Abstract : G protein-coupled receptors (GPCRs) are integral membrane proteins responsible for signal transduction of extracellular stimuli into the cell. Because of their widespread distribution throughout the human body and important roles in physiological processes, GPCRs are prominent drug targets and approximately 34% of all approved drugs interact with members of this superfamily.

6. 4. Free Fatty Acid Receptor 2 - A G protein coupled receptor with unique signaling properties in neutrophils

   Author : Simon Lind; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neutrophils; G protein coupled receptors; Free Fatty Acid Receptor 2; GPR43; Allosteric modulation; Transactivation; Cross-talk; Biased signalling; Functional selectivity;

   Abstract : The overall aim of the PhD thesis was to determine the role of neutrophil pattern recognition receptors in the initiation and resolution of inflammatory processes. Neutrophil pattern recognition receptors such as the formyl peptide receptors (FPRs) and the short free fatty acid receptors (FFARs) belong to the family of G protein coupled receptors (GPCR).

7. 5. Simulating Functional Cycles and Drug Modulation in Ligand-gated Ion Channels

   Author : Yuxuan Zhuang; Erik Lindahl; Grace Brannigan; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ion channels; molecular dynamics; markov state model; lipid modulation; nicotinic receptor; protein conformational transitions; Biophysics; biofysik;

   Abstract : Understanding the intricate motions and conformational changes that govern biological processes remains a fascinating and challenging endeavor. The research presented in this thesis aims to elucidate the dynamic processes underlying biological functions, specifically focusing on the dynamics of pentameric ligand-gated ion channels (pLGICs), which play a crucial role in signal transduction within the brain.
