This research shows that 2′-fucosyllactose, a natural compound found in breast milk, can significantly improve gut health in older mice. The treatment strengthened the intestinal barrier, reduced harmful inflammation, and increased beneficial bacteria populations. These findings suggest that 2′-FL could be developed as a food supplement to help older people maintain better digestive and immune health.
Researchers studied how the body fights a dangerous fungus called Sporothrix brasiliensis that causes sporotrichosis. They found that two immune receptors called dectin-1 and dectin-2 are crucial for protecting against this infection in mice. Surprisingly, these receptors work by activating killer immune cells and controlling regulatory immune cells, rather than through the typical immune response pathway scientists expected.
Some dangerous fungi produce a dark pigment called melanin that acts like a cloak, protecting them from the body’s immune system. This review explains how melanin blocks multiple immune defenses, including suppressing warning signals to immune cells, preventing immune cells from engulfing and killing the fungi, and even absorbing harmful reactive molecules. Understanding these sneaky tactics could help scientists develop new treatments that strip away this protective cloak, making the fungi vulnerable to both the body’s natural defenses and antifungal drugs.
This study examined pneumocystis pneumonia in immunocompromised patients who do not have HIV or transplants. Researchers found that older patients with other health conditions were at higher risk of death within 90 days. High levels of fungal markers and low immune cell counts were better predictors of poor outcomes than traditional inflammation markers, suggesting doctors should focus on early identification and personalized treatment approaches.
