Abstract

The intracellular parasite Toxoplasma gondii can invade any nucleated cell residing inside a parasitophorous vacuole (PV). Upon infection, the cytokine interferon gamma (IFNγ) is produced and elicits host defence mechanisms able to recognise the PV and destroy the parasite. Hereby, Guanylate binding proteins, ubiquitin and the E3 ubiquitin ligases Tripartite Motif Containing 21 (TRIM21) and TNF receptor associated factor 6 are targeted to the murine PV leading to its destruction. This study is the side product of research aiming to identify ubiquitinated substrates in a TRIM21-dependent fashion in murine cells infected with Toxoplasma.
