What this research studies

From a patient's view, scientists will use CRISPR/Cas9 to delete about ten targeted genes in the Valley fever fungus (Coccidioides posadasii) and test whether those changes reduce the fungus's ability to cause disease in laboratory models. Genes that show loss of virulence will then be examined in a related species (Coccidioides immitis) to confirm findings. The team will also create fluorescently labeled fungal strains to watch how the fungus interacts with host cells in the lab. These lab-based steps aim to build tools and knowledge that can guide future treatments, diagnostics, or vaccines.

Who could benefit from this research

Good fit: People affected by Valley fever or living in areas where the disease is common may be the most interested in supporting or benefiting from future studies that build on these findings.

Not a fit: Patients with unrelated health conditions or those seeking immediate treatment are unlikely to get direct or immediate benefit from this laboratory-focused project.

Why it matters

Potential benefit: If successful, this work could reveal fungal genes that become targets for new drugs, diagnostics, or vaccines that help prevent or treat Valley fever.

How similar studies have performed: CRISPR has successfully identified virulence genes in other fungi and pathogens, but applying these methods to Coccidioides is newer and less established.
