Related to Figure 7F.
MIC7HA tachyzoite enters a GFP-GPI U2OS cell. Invasion proceeds with the typical invagination of the host cell plasma membrane that initiates the folding of the nascent parasitophorous vacuole while the tachyzoite smoothly enters through the parasite-host cell junction, and this with a usual kinetics. Scale: 5 μm.
Related to Figure 7F.
Early abortive invasion of a GFP-GPI U2OS cell by a MIC7HA-treated tachyzoite (+RAPA). The tachyzoite apex starts to engage into the host cell membrane promoting a narrow and limited invagination of the latter but the tachyzoite does not position properly and rapidly withdraws from the invagination while host cell membrane projections can be seen extending along the tachyzoite body. Eventually, the tachyzoite escapes from the cell membrane and exhibits typical circular and twirling gliding behaviour. Scale: 5 μm.
Related to Figure 7F.
MyccWT-treated tachyzoite (+RAPA) enters a GFP-GPI U2OS cell. Invasion proceeds with the same features and kinetics as for the MIC7HA tachyzoite. The parasite passes though the constricted parasite-zoite junction and enters into the budding nascent parasitophorous vacuole. Scale: 5 μm.
Related to Figure 7F.
Early abortive invasion of a GFP-GPI U2OS cell by a MyccMut-treated tachyzoite (+RAPA). The tachyzoite engages the conoid into the cell membrane, which locally invaginates, but does not proceed further and instead markedly deforms prior to eventually disengaging from the cell. Scale: 5 μm.
