Researchers at ETH Zurich have identified a proteomic signature that could recognize long COVID six months after acute infection. Biologically, the signature indicated that the complement system remained active in patients with long COVID six months after infection. Translationally, it could lead to a diagnostic test for long COVID, and suggests that targeting the complement system could be a therapeutic approach to prevent or treat the disorder.

A new gene editing method uses the CRISPR technique to modify the cells of an organ in vivo, creating a mosaic used to identify the effects of each altered gene. Scientists from the Swiss Federal Institute of Technology (ETH) in Zürich developed this technology called AAV-Perturb-seq, based on adeno-associated virus (AAV) to target, edit and analyze single-cell genetic perturbations.
A new bacteriophage-based rapid test has the potential to identify the specific pathogen causing a urinary tract infection (UTI) at the point of care, enabling targeted use of antibiotics.
The test uses naturally occurring phages identified as predators of Escherichia coli, Klebsiella and Enterococci that are genetically modified to make any bacterium they invade bioluminescent.
In a proof-of-concept study, researchers at ETH Zurich, Switzerland, were able to reliably detect the pathogenic bacteria in a urine sample in less than four hours. That compares to the 18 – 30 hours it takes to culture samples in a central lab and to identify a specific microbe using conventional diagnostics.
Monoacylglycerol lipase (MAGL) is a key regulator of the endocannabinoid system (ECS), which has a critical neuromodulatory involvement in numerous functional mechanisms in the CNS. Based on this, MAGL is considered a promising therapeutic target in neuroinflammation and neurodegeneration. Researchers from ETH Zürich and affiliated organizations have recently presented their work on (R)-[18F]YH-134, a novel reversible radiotracer for imaging MAGL in the brain.
A new method for controlling naturally magnetized bacteria has improved the prospects of applying them as vehicles for intratumoral delivery of cancer drugs and in hyperthermia therapy.
A new method for controlling naturally magnetized bacteria has improved the prospects of applying them as vehicles for intratumoral delivery of cancer drugs and in hyperthermia therapy. The advance will provide a better way of directing the movement of systemically administered bacteria, using external magnetic fields to target them to tumors sited deep in the body. It also points to a possible route for engineering existing bacteria-based anticancer constructs for better targeting.
LONDON – COVID-19 excepted, biomedical research projects and clinical trials are grinding to a halt across Europe, as universities shut down and administrators stop any work not related to the coronavirus.
