Researchers at the RIKEN Center for Biosystems Dynamics Research in Japan have deployed improved genetically modified human stem cell-derived retinal transplants to treat rats with retinitis pigmentosa, a major cause of hereditary human blindness.
Drugs targeting receptors of the neurotransmitter serotonin (5-hydroxytryptamine [5-HT]) are widely used in neuropsychiatry and some such agents, most notably psilocybin, have shown potential for further drug development, but hallucinogenic effects have limited their clinical use. The findings of a new multicenter Chinese structural pharmacology study may now provide a solid basis for the structure-based design of safe and nonhallucinogenic psychedelic analogues with therapeutic efficacy, the authors reported in the January 28, 2022, edition of Science.
A novel dual-action small molecule developed by a team led by scientists at Kyungpook National University (KNU) in Daegu, South Korea, has been shown to improve the neuropathological features of Alzheimer's disease (AD) in mice, the authors reported in the Jan. 18, 2022, edition of ProceedingsoftheNationalAcademyofSciences.
Destroying senescent cells in the aging stem cell niche, either genetically or pharmacologically using the small-molecule senolytic ABT-263 (navitoclax; Abbvie Inc.), enhanced hippocampal neurogenesis and cognitive function in mice, a Canadian study led by scientists at the University of Toronto has found.
The discovery of a hormone regulating blood glucose levels independently of insulin could lead to the development of new diabetes therapies and open up promising new avenues in metabolism research, according to a study led by researchers at the Salk Institute for Biological Studies.
Trisomy 21, the abnormal third copy of chromosome 21 causing developmental disorders in Down syndrome, has been shown to promote reorganization of the entire neural progenitor cell (NPC) genome, with the resulting gene transcription and cell function disruption being so similar to senescence that anti-senescence drugs could correct them in cell cultures.
Combining the metabolites glutamine or inosine with ampicillin (AMP) could represent a new therapeutic approach to antimicrobial resistance that also avoids the development of acquired resistance to next-generation antibiotics, according to a new Chinese study led by scientists at Sun Yat-sen University (SYSU) in Guangzhou.
An international study led by scientists at the University of Exeter in the U.K. suggests how to combine antibiotic and bacteriophage therapy optimally, in order to reduce antibiotic use and potentially prevent multidrug resistance in bacteria.
An international collaborative study led by Chinese researchers at Wuhan University is the first to have discovered a new small molecule, termed IMA-1, and shown it to be safe and effective for the treatment of nonalcoholic steatohepatitis (NASH) in mouse and macaque models.
Modulation of a single amino acid in the reprogramming factor Kruppel-like factor 4 (KLF4) has been demonstrated to markedly improve natural transcription factor function and to result in faster and more effective reprogramming of somatic cells into induced pluripotent stem cells.
