Researchers at Korea University have achieved a significant breakthrough in regenerative medicine. They have demonstrated how fibroblast growth factor 4 and Ascorbic acid, known as vitamin C, can induce the trans-differentiation of fibroblasts into functional cardiomyocytes. This discovery activates key cellular pathways and offers hope for developing treatments for cardiovascular diseases, the leading cause of death worldwide.
In a study published recently in Nature Chemical Biology, Weizmann Institute of Science researchers solved the mystery and provided a comprehensive description of the “biological recipes” that cells use to cook up such a varied and useful menu of crystals.
An often-overlooked mechanism of gene regulation may be involved in the failure of antifungal drugs in the clinic. This has been discovered by a German-Austrian research team led by the Leibniz Institute for Natural Product Research and Infection Biology - Hans Knöll Institute (Leibniz-HKI). The study focused on the mold fungus Aspergillus fumigatus, which can cause life-threatening infections, especially in immunocompromised people. Targeted changes to the fungal RNA allow a better understanding of the molecular mechanisms, which are responsible for the development of resistance and the fungus' defense mechanisms against drugs.
It´s been long known that bacteria are becoming increasingly resistant to antibiotics. The risk of no longer being able to successfully treat bacterial infections is constantly increasing. Equally critical - although not in the public focus - is the resistance of fungal pathogens to antimycotics, which is exacerbated by the massive use of similar active ingredients in agriculture. This problem is reflected in alarming data: With over one billion infections and around 3.75 million deaths per year, fungal infections are a significant threat to humans - the trend is rising.
The treatment of fungal infections is currently based on a few groups of medical active substances such as echinocandins, polyenes, azoles or the synthetic molecule fluorocytosine. The team led by Matthew Blango, head of a junior research group at the Leibniz-HKI, used the known mode of action of fluorocytosine on A. fumigatus as the basis for the investigation of the development of fungal resistance.
As we age our bodies are flooded by aging, or senescent, cells, which have stopped dividing but, instead of dying, remain active and build up in body tissues. Recent studies have shown that getting rid of these cells might delay age-related diseases, reduce inflammation and extend lives. Despite the great potential, however, there is currently no drug that can target these cells directly and efficiently.
Now, Weizmann Institute of Science researchers suggest an alternative approach. In a new study published in Nature Cell Biology, they reveal that senescent cells build up in the body by clogging up the immune system, thereby preventing their own removal. The scientists demonstrated in mice how to unclog this blockage using immunotherapy, the new generation of treatments that is revolutionizing cancer therapy. These findings could pave the way for innovative treatment of age-related diseases and other chronic disorders.
