How the brain sugar inositol helps Cryptococcus infect the brain
The role of inositol in Cryptococcus biology and pathogenesis
['FUNDING_R01'] · RUTGERS BIOMEDICAL AND HEALTH SCIENCES · NIH-11322986
This project explores if the brain sugar inositol helps the Cryptococcus fungus cross into the brain and cause meningitis, aiming to help people at risk of fungal brain infections.

What this research studies
Researchers use laboratory and mouse experiments to see how inositol affects Cryptococcus growth, capsule makeup, and the fungus's ability to stick to and cross the blood-brain barrier. They compare normal fungi to mutants lacking inositol uptake or breakdown and study specific fungal genes (like Itr4 and Hlh6) that control inositol use. Cell-based blood-brain barrier models and biochemical assays are used to observe binding and traversal steps. The team builds on prior findings that inositol-rich conditions increase fungal virulence in the brain.
Who could benefit from this research
Good fit: The findings are most relevant to people at high risk for cryptococcal meningitis—for example those with weakened immune systems such as advanced HIV/AIDS—even though this grant primarily uses lab and animal models rather than enrolling patients.
Not a fit: People without risk factors for cryptococcal infection or those with non-fungal forms of meningitis are unlikely to see direct benefit from this specific fungal-focused laboratory research.
Why it matters
Potential benefit: If successful, this work could point to new ways to block fungal entry into the brain and reduce deaths from cryptococcal meningitis.
How similar studies have performed: Previous laboratory and mouse work from these investigators has already shown that inositol promotes fungal brain entry and identified fungal genes involved, so this project extends promising preclinical findings.
