Researchers from Stanford University seek patent protection for an ultrasound-based device which converts electrical energy into acoustic energy to treat inflammatory disorders. The neuromodulator device targets the cholinergic anti-inflammatory pathway (CAP), which regulates the innate immune response to injury, pathogens, and tissue ischemia.
The broadest view of post-mortem brains in Alzheimer’s disease (AD) has unveiled the genome, transcriptome and epigenome alterations of this neurodegenerative condition. The coordinated research, directed by scientists at the Massachusetts Institute of Technology (MIT), also described new cellular pathways that could help the scientific community design new therapies. Four simultaneous studies published on Sept. 28, 2023, in Cell, presented a brain single-cell atlas of AD, exposed the damage that affects DNA, and described the processes that alter the microglia and dysregulate the epigenome.
A team from Siemens Medical Solutions Inc. presented a new artificial intelligence (AI) model that can predict people’s risk of multiple sclerosis (MS), at the 2023 American Association for Clinical Chemistry (AACC) annual scientific meeting in Anaheim, Calif.
Unlike amphibians, mammals do not regenerate appendages. Except when they do. “If you amputate one of the branches off of the antler [of a reindeer], it will also regenerate,” Jeff Biernaskie told BioWorld. Even without amputation, the antlers of both male and female reindeer regenerate annually, including their skin. That regeneration is “the only large mammal model of true skin regeneration,” he said.
Treating mice with butyrate, a short-chain fatty acid that is normally produced by beneficial gut microbes, prevented anaphylactic shock in allergic mice when they were exposed to peanuts after treatment. It also reduced inflammation in animals with colitis.
South Korea’s Medipost Co. Ltd. is gearing up for phase III trials in the U.S. of its stem cell therapy, Cartistem, an allogeneic human umbilical cord blood-derived mesenchymal stem cell therapy for treatment of knee articular damage in patients with osteoarthritis.
Galvani Bioelectronics Ltd. reported the first patient implanted with its experimental direct splenic nerve stimulation therapy for rheumatoid arthritis (RA). The first-in-human implant is part of a small trial at the NHS Greater Glasgow & Clyde Health Board in Scotland.
Merck KGaA is partnering with Neuroloop GmbH, a subsidiary of B. Braun SE, to develop a neurostimulator device that can complement existing drug therapies for people with chronic inflammatory diseases. The collaboration aims to adapt Neuroloop’s neurostimulation platform to enable targeted treatment of chronic inflammatory ailments. The new bioelectronics program intends to open up new technologies and markets that are close to Merck’s electronics and health care business sectors.
The Human Skin Cell Atlas, comprising transcriptomes of 528,253 single cells, shows that cellular processes involved in skin development in embryos are reactivated in inflammatory skin diseases. In addition to suggesting potential new drug targets for atopic dermatitis and psoriasis, the transcriptomes provide a new route to understanding other inflammatory diseases, and provide a template for culturing skin for wound repair, according to the authors of a paper published in the Jan. 22, 2021, issue of Science.
Neurotech startup Nēsos Corp. has emerged from stealth with a novel approach for the treatment of rheumatoid arthritis. Using wireless earbuds, the technology delivers electrical fields to targeted areas of the brain to help regulate immune function. The company recently raised $16.5 million in a series A round to advance clinical development of its first e-immunotherapy product.
