Proteins made early in Valley fever infection and how they affect disease and vaccines
Early in vivo expressed antigens and their role in virulence, immune response, and vaccines for coccidioidomycosis
Researchers are finding the proteins Valley fever fungi make right after they infect the lungs to help create better tests and vaccines for people at risk.

What this research studies
This project examines which fungal genes are turned on early during lung infection, focusing on proteins (antigens) produced soon after exposure. Scientists use mouse infection models, transcriptional analysis, and bioinformatics to identify proteins that trigger immune responses or influence virulence. Promising antigens will be tested in animals with adjuvants to see if they reduce disease or work as vaccine components. The goal is to provide data that can guide new diagnostics, treatments, and future human vaccine trials.
Who could benefit from this research
Good fit: People who live in or travel to areas where Valley fever is common, or who have had Valley fever, would be likely candidates for future vaccine or diagnostic studies arising from this work.
Not a fit: Patients with unrelated medical conditions or those not exposed to Valley fever are unlikely to receive direct benefits from this early-stage laboratory research.
Why it matters
Potential benefit: Could lead to earlier, more accurate tests and new vaccines that prevent or reduce severe Valley fever.
How similar studies have performed: Some prior animal studies have shown promising vaccine targets against Coccidioides, but there is not yet a licensed human vaccine and much of this work is advancing novel antigen leads.
