A study in a mouse model of tau protein build-up in the brain, similar to that seen in later stage Alzheimer’s disease (AD), shows that changes to the microbiome in these animals can impact the degree and progression of neurodegeneration observed. As reported in the Jan. 12, 2023, study published in Science, the researchers found that mice that were germ free and those given antibiotics to change their gut microbiome early in life had significant reductions in brain atrophy compared with those with a standard microbiome.
Skynor Medical (Shanghai) Co. Ltd. has raised ¥100 million (US$15 million) in a financing round to step up its efforts in product development and market expansion. More specifically, the Shanghai-based company intends to use the funds to develop its interventional treatment solutions for neuro and peripheral vascular diseases, as well as expand them to markets at home and abroad.
Repeat expansions of two or more base pairs cause dozens of neurological disorders – Huntington’s disease, which is caused by an expansion of the triplet CAG in the coding sequence for huntingtin, is perhaps the most famous one. Now, investigators at Stanford University have shown that cancer genomes, too, frequently feature repeat expansions.
Medical technology company Synchron Inc. completed an AU$110 million (US$73.9 million) series C round that will allow the company to conduct a feasibility study and pivotal trial of its implantable brain computer interface that can interpret and stimulate parts of the brain.
Natus Medical Inc. entered into a definitive agreement to acquire EU-based neurophysiology solution provider Micromed Group SpA. The transaction is expected to close in early 2023, subject to regulatory approvals from the Italian Council of Ministers’ Presidency and the French Ministry of Economy and Finance. Full terms of the transaction have not been disclosed. “The idea behind this acquisition is to provide a single portfolio of neurodiagnostic and neuromonitoring products in the EU and the whole world,” Thomas Sullivan, CEO of Natus Medical, told BioWorld.
Researchers have identified a link between amyloid plaques and dysfunctional neuronal conduction in animal models of Alzheimer’s disease (AD). Their study, which was published in the Dec. 1, 2022, issue of Nature, suggests new ways to think about AD, as well as badly needed potential alternatives to plaque removal to fight the disease.
While NASA gets the glory for exploration of the vast unknown of space, Bionaut Labs Ltd. hopes to reap similar fame by transforming travel through the brain with Bionauts, microrobots designed to deliver therapeutic payloads across the blood-brain barrier. To help achieve that mission, the company raised $43.2 million in a series B financing round led by Khosla Ventures.
Mdoloris Medical Systems SAS and Pprs SAS reported a joint venture to launch ANI Guardian, a connected medical device that continuously and non-invasively tracks pain levels and well-being in a range of non-verbal or cognitively impaired people.
Stimulating the brain via implanted electrodes is used to treat both movement disorders such as Parkinson’s disease, and some psychiatric conditions such as obsessive compulsive disorder. But researchers are also working on ways to make such implanted electrodes listen instead of talk – and translate neuronal signals for people that have lost the ability speak, or the ability to move.
One way psychiatric disorders differ from neurological disorders is by the absence of anatomically defined neuropathology. “Alzheimer's disease, Parkinson's disease or stroke have a very clear picture of what cells are changing and how they're changing. The specific changes are very clear under a microscope, but in psychiatric diseases one hasn't been able to see that,” Daniel Geschwind told BioWorld.
