One in three people carry this brain parasite but the body has a kill switch
Why it matters: This discovery offers a crucial understanding of how the body naturally combats a widespread brain parasite, potentially paving the way for new treatments and preventative measures, especially for those with weakened immune systems.
- UVA Health identifies caspase-8 as a crucial enzyme that triggers self-destruction in infected CD8+ T cells, effectively eliminating the Toxoplasma parasite.
- Toxoplasma gondii demonstrates a shocking survival tactic by infecting the very immune cells (CD8+ T cells) meant to destroy it.
- Individuals with compromised immune systems are particularly vulnerable to toxoplasmosis, highlighting the importance of this discovery for developing targeted therapies.
A staggering one in three people harbor the Toxoplasma gondii brain parasite, but UVA Health researchers have discovered a critical self-destruct mechanism within our immune cells that keeps the infection in check. This breakthrough reveals how infected CD8+ T cells, key immune defenders, sacrifice themselves via the caspase-8 enzyme to eliminate the parasite, offering new hope for immunocompromised individuals vulnerable to toxoplasmosis.
