Tetrahymena pyriformis
Biological Process
phagocytosis, engulfment
Cellular Component
phagocytic vesicle
The nascent digestive vacuole forms as the membrane of flattened vesicles fuse with the single membrane of the cytopharynx between the lamellae (2 microtubules forming a lamella) that are connected al...

Paramecium multimicronucleatum
Biological Process
oral apparatus organization
Cellular Component
pre-autophagosomal structure membrane
The nascent phagosome membrane has a dense coat of acidosomes docked at its cytosolic surface well before the nascent vacuole pinches off the cytopharynx. This micrograph is a quick-freeze deep-etch i...

pre-autophagosomal structure membrane
Monoclonal antibody for antigen B2 (called mAb PC-1 in Fok et al., Eur. J. Cell Biol. 40:1-8, 1986) is located on the cytopharynx and along the cytopharyngeal ribbons. It can be seen here on the DV-I ...

NCBI Organism Classification
Paramecium caudatum
Biological Process
phagocytosis
Cellular Component
oral apparatus
The collapsed cytopharyngeal membrane extends from the open cytopharynx into the cytosol. This membrane is associated with many docked acidosomes, vesicles that contain V-type proton translocating ATP...

oral apparatus
Posterior end of the buccal cavity with a nascent phagosome attached to the cytopharynx. The ribbed wall has ended and the cytopharynx is greatly reduced. The quadrulus goes to the end of the buccal c...

NCBI Organism Classification
Vorticella convallaria
Biological Process
response to food
Cellular Component
oral apparatus
Food vacuoles arise from the single membrane that lines the cytopharynx. Vesicles, similar to discoidal vesicles, attach to the cytopharyngeal microtubules (lamellar clumps) that arise from the dorsal...

endosome
Adapted with permission. Extensions of cytopharyngeal microtubular ribbons that pass into the endoplasm from the cytopharynx. Discoidal vesicles bind to one side only of these ribbons (the anterior si...

NCBI Organism Classification
Paramecium caudatum
Biological Process
phagocytosis
Cellular Component
vesicle membrane
At the cytopharynx the acidosomes come in contact with the carrier vesicles that are derived from early endosomes. These carrier vesicles bind to the microtubular ribbons as do the acidosomes. The car...
