Inmune Bio Inc., together with a collaborator at University of California, Irvine School of Medicine, has shown targeting soluble TNF (sTNF) using a dominant-negative TNF (DN-TNF) biologic significantly decreased muscle damage in a murine mdx model of Duchenne muscular dystrophy (DMD) and showed a statistically significant increase in muscle regeneration.

Amyotrophic lateral sclerosis (ALS) is the most frequent adult-onset motor neuron disease, and it is pathologically related with frontotemporal dementia (FTD). Genetic studies have identified C9ORF72 as a major genetic cause of ALS/FTD. Further genetic analyses and validation studies have identified some other genes associated with ALS risk, highlighting among them the NUP50 gene, which encodes nuclear pore complex protein Nup50.

Research shows that individuals with schizophrenia have abnormal gene expression patterns in their brains compared with people without the condition. In a study published in PLOS Biology on Jan. 24, 2023, the authors reported that many genes in brain tissue from the dorsolateral prefrontal cortex, a region involved in cognition, have expression patterns that follow a 12-hour cycle. The investigators found that these patterns were largely lost in people with schizophrenia.

The burgeoning psychedelic therapeutics market experienced a boost Jan. 25 as Small Pharma Inc. announced its synthetic, intravenous formulation of N,N-dimethyltryptamine (DMT), SPL-026, led to a statistically significantly, rapid reduction in depression symptoms in patients with major depressive disorder in a phase IIa trial, thus meeting its primary endpoint. DMT is a powerful hallucinogenic tryptamine substance which works as a 5-HT receptor agonist. It is found naturally in various plants, and is a schedule I controlled substance in the U.S. Although lesser known than other psychedelics such as magic mushrooms and LSD, it produces short-lived but intense auditory and visual hallucinogenic effects.

ABVC Biopharma Inc is headquartered in San Francisco but it has its roots in Taiwan where it is digging into traditional medicine and validating it for the modern world. “There are a number of drugs that can’t be synthesized in the lab,” ABVC CEO Howard Doong told BioWorld, so he is going back to the original source of traditional Chinese medicines to validate them using traditional drug development models.

Researchers at the Dana-Farber Cancer Institute have been able to identify proteins that were released from muscles during exercise in relatively small quantities. Using their method, the team was able to demonstrate that the neurotrophic factor prosaposin was produced during exercise. Prosaposin is “a well-known CNS neurotrophic factor, but has never been seen to come out of muscle or fat,” Bruce Spiegelman told BioWorld. Spiegelman is a researcher at the Dana-Farber Cancer Institute and Stanley J. Korsmeyer Professor of Cell Biology and Medicine at Harvard Medical School.

A new epigenetic editing technique has restored the functionality of neurons in Rett syndrome (RTT), a rare neurodevelopmental disease associated with a mutation of the MECP2 gene on the X chromosome. The origin of this disorder is a heterozygous mutation of the MECP2 (methyl CpG-binding protein 2) gene. Homozygosity is lethal and as it is associated with the X chromosome; Rett mostly affects girls, inhibiting the development of their motor skills and communication.
