Nanoluciferase-based complementation assay for systematic profiling of GPCR-GRK interactions.

Methods Cell Biol 2022 4;169:309-321. Epub 2022 May 4.

Department of Infection and Immunity, Immuno-Pharmacology and Interactomics, Luxembourg Institute of Health (LIH), Esch-sur-Alzette, Luxembourg; Department of Oncology, Tumor Immunotherapy and Microenvironment, Luxembourg Institute of Health (LIH), Luxembourg City, Luxembourg.

G protein-coupled receptor kinases (GRKs) are a family of seven soluble receptor-modifying enzymes which are essential regulators of GPCR activity. Following agonist-induced receptor activation and G protein dissociation, GRKs prime the receptor for desensitization through phosphorylation of its C terminus, which subsequently allows arrestins to bind and initiate the receptor internalization process. While GRKs constitute key GPCR-interacting proteins, to date, no method has been put forward to readily and systematically determine the preference of a specific GPCR towards the seven different GRKs (GRK1-7).

Responses of reconstituted human bronchial epithelia from normal and health-compromised donors to non-volatile particulate matter emissions from an aircraft turbofan engine.

Environ Pollut 2022 May 24:119521. Epub 2022 May 24.

Institute of Anatomy, University of Bern, 3012, Bern, Switzerland. Electronic address:

Health effects of particulate matter (PM) from aircraft engines have not been adequately studied since controlled laboratory studies reflecting realistic conditions regarding aerosols, target tissue, particle exposure and deposited particle dose are logistically challenging. Due to the important contributions of aircraft engine emissions to air pollution, we employed a unique experimental setup to deposit exhaust particles directly from an aircraft engine onto re-differentiated human bronchial epithelia (HBE) at air-liquid interface under conditions similar to in vivo airways to mimic realistic human exposure. The toxicity of non-volatile PM (nvPM) from a CFM56-7B26 aircraft engine by sampling was evaluated under realistic engine conditions and exposing HBE derived from donors of normal and compromised health status to exhaust for one hour followed by biomarker analysis 24hours post exposure.
