Researchers studied a specific gene called Sec2p in a dangerous fungus that causes serious lung infections in people with weak immune systems. By removing this gene, they found the fungus grew much slower, was less deadly to mice, and the infected animals survived longer. This discovery could lead to new treatments for fungal infections by targeting the Sec2p gene.
Researchers developed a vaccine using special immune cells called dendritic cells loaded with proteins from the fungus that causes sporotrichosis. When vaccinated mice were later infected with the fungus, they showed stronger immune responses and had lower levels of the fungus in their bodies. This suggests that dendritic cell-based vaccines could be a promising new treatment approach for sporotrichosis, a serious fungal infection that is difficult to treat with current medicines, especially in people with weakened immune systems.
Scientists studied a gene called Sec2p in a harmful fungus that causes serious lung infections in people with weak immune systems. When they removed this gene, the fungus grew more slowly and was much less dangerous to infected mice, with 67% of mice surviving compared to only 22% with normal fungus. The gene controls how the fungus breaks down its own cell parts for nutrition and repairs its cell wall, so blocking it weakens the fungus significantly.
Researchers tested a new drug called APC6 that works by trapping zinc, which fungi need to survive. In mouse studies of a dangerous resistant fungus called Candida auris, APC6 saved all treated mice while most untreated mice died. The drug also reduced fungal infections in organs without causing serious side effects, suggesting it could become a new treatment option for serious fungal infections resistant to current medicines.
