Prodigiosin-based nanoformulation selectively disrupts cancer cells

Together with colleagues from the University of Palermo, KFU employees offer a nano preparation based on biocompatible halloysite nanotubes and bacterial pigment prodigiosin; the latter is known to selectively disrupt cancer cells without damaging the healthy ones.

Type III interferons can increase risk of bacterial "superinfections" in the lung, research shows

Interferons and other cytokines produced by the immune system are important defenses against viral infections, but as we have seen in COVID-19, they can also contribute to damaging, potentially life-threatening lung inflammation.

Researchers question the mechanism of retinitis pigmentosa

Researchers who made a knock-in mouse-model of the genetic disorder retinitis pigmentosa 59, or RP59, expected to see retinal degeneration and retinal thinning. As reported in the journal Cells, they surprisingly found none, calling into question the commonly accepted -- though never proved -- mechanism for RP59.

Researchers use human stem cell models to analyze degeneration in glaucoma

More than 3 million Americans have glaucoma, a serious eye condition causing vision loss. Using human stem cell models, researchers at Indiana University School of Medicine found they could analyze deficits within cells damaged by glaucoma, with the potential to use this information to develop new strategies to slow the disease process.
