12. RNA interference and nanomedicine join forces to fight dangerous fungal infectionsСр, 26 мар[-/+]

Категория^(?)

Fungal infections are on the rise globally. According to a study by the Manchester Fungal Infection Group, in 2022, approximately 6.5 million people were infected by a pathogenic fungus, and about 3.8 million died as a result—nearly twice as many as in 2012. Even with medications, known as antifungals, the mortality rate for invasive infections caused by the mold Aspergillus fumigatus is as high as 85%. As resistant fungal strains increase, treatment becomes more difficult, and new therapies are urgently needed.
