Researchers find microglia are key to protecting brain from viral infection
The team found microglia and CD8 T cells were vital to protecting neurons from vesicular stomatitis virus (VSV) infection and suggest loss of taste and smell in COVID-19 could be due to a certain mechanism of infection.
Investigational anti-SARS-CoV-2 molecules show efficacy in pre-clinical studies
Pre-clinical testing of the COVIDTRAP™ (STI-4398) protein and STI-1499 antibody reveal they can inhibit SARS-CoV-2 from infecting cells.
A new vision: restoring eyesight using a novel gene therapy technique
Scientists created a technique to give photoreceptors infrared-light sensitivity, allowing the animal models to see infrared heat signatures.
Researchers suggest animal experiments may be too standardised to be reproducible
Experts suggest that increasing biological and conditional variations in their experiments could not only make them more reproducible but also reduce the total number of animals required.
TiPARP activation should be the target of future cancer drugs, says researcher
Scientists reveal activating tumour suppressor protein TiPARP results in the degradation of several transcription factors implicated in cancer survival.
3D map of the heart’s intracardiac nervous system (ICN) revealed
The 3D map, created using Knife-Edge Scanning Microscopy and analysed using laser capture microdissection, reveals new insights about the nervous control of the heart.
Novel complement inhibitor improves ischemic stroke recovery in mice, say researchers
Administering a novel complement protein blocker (B4Crry) alongside reperfusion therapy improved cognitive and motor recovery in a model of ischemic stroke.
Cancer mutation could be used to target CRISPR therapy
Researchers reveal protospacer adjacent motif mutations (PAM sites) on the NRF2 gene of cancers could be used to guide CRISPR gene editing.
Researchers identify 27 biomarkers of COVID-19 disease severity
Mass spectrometry revealed biomarkers that could be used as drug targets for developing novel therapeutics or to predict whether a patient with COVID-19 will become severely ill.
Novel compound improves symptoms of fatty liver disease in mice
The novel peripheral serotonin antagonist, based on Parkinson’s drug pimavanserin, increased glucose tolerance and lean body mass in a murine model of non-alcoholic fatty liver disease (NAFLD).
Mapping SARS-CoV-2 infection in the airway
Researchers found there is a gradient of SARS-CoV-2 infectivity down the airway and that the severe pneumonia symptoms may be caused by aspiration of oral contents into the lungs.
Flow synthesis technology enables faster protein production
The novel protocol allows proteins over 100 amino acids long to be synthesised in hours and include amino acids that do not occur in the human proteome.
Selectively increased Dnmt3a2 protein expression improves memory recall
Researchers found increasing levels of Dnmt3a2 in neurons activated at the time of making a memory, improved its recall in mice.
SARS-CoV-2 mouse model recapitulates human infection
Researchers develop a knock-in mouse expressing human angiotensin-converting enzyme 2 (hACE2) to model SARS-CoV-2 infection for research and therapeutic or vaccine testing.
