1620-Toxoplasma&Endoplasmic Reticulum Membrane Contact
This research identifies how the parasite Toxoplasma gondii interacts with host cells by establishing membrane contact sites (MCS) with the endoplasmic reticulum (ER). Using a specialized fluorescence sensor and CRISPR-based screening, scientists discovered that the parasite protein TgROP1 acts as a physical tether to the host cell. Specifically, TgROP1 mimics a biological motif to bind with host proteins VAPA and VAPB, facilitating communication between the pathogen and the host organelle. The study demonstrates that these connections are vital for the parasite, as removing these host…
