AC Immune SA has patented 4h-imidazo[1,5-b]pyrazole derivatives and labeled compounds targeting α-synuclein (SNCA). They are reported to be useful for diagnosis of multiple system atrophy, Parkinson’s dementia, Lewy body dementia, Alzheimer’s and Parkinson’s disease, among others.
α-Synucleinopathies constitute a set of neurological disorders including Parkinson’s disease (PD), dementia with Lewy bodies, multiple systems atrophy (MSA), and other rare disorders. The development of positron emission tomography (PET) tracers for imaging α-synuclein aggregates is essential for performing efficient and accurate diagnosis, tracking disease progression and monitoring efficacy of potential therapies.
Previous studies have identified a promising target and potential biomarker for diagnosing and treating gastrointestinal and esophageal cancers: claudin18.2 (CLDN18.2), a tight junction protein overexpressed in these and other solid tumors.
Theranocure Co. Ltd. has divulged gadolinium complexes targeting β-amyloid protein acting as magnetic resonance imaging (MRI) contrast agents reported to be useful for the diagnosis of Alzheimer's disease and the treatment of Parkinson's and Alzheimer's disease.
Researchers at Stanford University School of Medicine have developed a method to measure several thousand metabolites, including proteins, metabolites, inflammatory markers such as cytokines and, to a degree, lipids. “It’s like Theranos, except it works,” corresponding author Michael Snyder, director of the Center for Genomics and Personalized Medicine at Stanford Medicine, told BioWorld.
Being able to detect cancers early can substantially improve survival, but most early detection tests for cancer rely on expensive and sophisticated molecular techniques that might be difficult to implement in resource strapped environments. Two new studies published last week attempt to overcome this problem.
CRISPR, or clustered regularly interspaced palindromic repeats, is transforming biomedical research, and making rapid inroads into the clinic, with its ability to easily target specific DNA and RNA sequences. CRISPR itself is made of RNA. It recognizes target sequences and delivers CRISPR-associated (Cas) proteins, nucleases that cut the target sequence. In two papers published online in Nature on Jan. 4, 2023, researchers have demonstrated that a recently discovered type of Cas protein, Cas12a2, can degrade double-stranded DNA when its associated CRISPR guide RNA recognizes its target sequence.
Scientists from the Icahn School of Medicine at Mount Sinai have found a sexual dimorphism of depression based on the different expression of a molecule that could be developed as a therapeutic strategy. “There is a big sex difference in depression. Women are much more likely to have depression than men. They tend to have different subsets of symptoms. They tend to respond better to different antidepressants, and the depression tends to be more severe,” Orna Issler, the first author of the study and a postdoctoral researcher at the Nash Family Department of Neuroscience, Friedman Brain Institute, Icahn School of Medicine at Mount Sinai, told BioWorld. Their project, directed by Eric Nestler, a professor of neuroscience and director of the Friedman Brain Institute at the Icahn School of Medicine at Mount Sinai, had the aim to understand the biology of these sex differences of depression and to find therapeutic targets for it.
