Briefings

A Virginia Tech-led study identified a protein named DDP essential for Toxoplasma gondii reproduction. When this protein was disabled, the parasite ceased multiplying entirely, suggesting a potential therapeutic target for immunocompromised individuals. The research was conducted in the Center for One Health Research at Virginia-Maryland College of Veterinary Medicine.

Key points

• The protein DDP is essential for Toxoplasma gondii to build offspring, as disabling it stops parasite multiplication entirely.
• The study was led by Raj Gaji, an assistant professor of parasitology at Virginia-Maryland College of Veterinary Medicine.

Context

This research addresses a deadly disease affecting immunocompromised people, offering a new avenue for targeted treatments by targeting a specific parasite protein.

Limitations

Evidence is limited to a single study from 2026; no additional data on patient outcomes, long-term effects, or broader epidemiological context is provided.
