On July 11, 2026, researchers at the University of California - San Diego announced a groundbreaking development in the fight against fungal infections. They have successfully transformed human immune cells into antifungal nanoparticles that specifically target Candida albicans, a fungus responsible for serious infections. This innovative approach could significantly enhance treatment options for infections that are increasingly difficult to manage.
Innovative Antifungal Nanoparticles Created
The research team, led by Liangfang Zhang, a professor in the Aiiso Yufeng Li Family Department of Chemical and Nano Engineering at UC San Diego, has developed nanoparticles that not only attack the fungus but also enhance the body’s immune response. Traditional antifungal medications often lose effectiveness due to evolving resistance in fungi, making this new strategy particularly promising.
The nanoparticles are constructed from the outer membranes of human macrophages, which are crucial immune cells in the body. By isolating these membranes and fusing them onto biodegradable polymer nanoparticles, the researchers created nanodiscs that mimic the properties of macrophages, allowing them to evade the immune system while targeting fungal cells more effectively.
Mechanism of Action Against Fungal Cells
Once the nanodiscs attach to the Candida albicans cells, they weaken the fungal cell's protective membrane, creating openings that lead to cell death. This method contrasts sharply with traditional antifungal treatments that target specific molecules, which can result in resistance. The size of the nanodiscs, approximately 10 to 20 nanometers, enables them to interact directly with the fungal membranes, a feat that full-sized macrophages cannot achieve.
