In this week’s Editors’ Choice piece, we highlight a study by Ten Hoeve, @HAKIMIMohamedA1, @BarraganLab, and colleagues in @cellhostmicrobe that shows how the parasite #Tgondii makes macrophages migrate.  Read a summary in #ScienceSignaling: scim.ag/Tc

we're very excited to share our latest work! Blood-brain barrier-restricted translocation of Toxoplasma gondii from cortical capillaries doi.org/10.7554/eLife.69182
Blood-brain barrier-restricted translocation of Toxoplasma gondii from cortical capillaries

Blood-brain barrier-restricted translocation of Toxoplasma gondii from cortical capillaries

The invasion of Toxoplasma to the CNS across cortical capillaries is restricted by the integrity of the blood-brain barrier (BBB) and exacerbated by the inflammatory response.

"We have decoded how the parasite takes control of immune cells, converting them into moving "zombies" which spread the parasite in the body," says Professor Antonio Barragan. Find out how the cat parasite Toxoplasma gondii exploits immune cells to reach the human brain
