  • That happens through a process called endocytosis, in which sections of the membrane engulf substances and transport them into the cell as vesicles.
  • receptor-mediated endocytosis

Examples

  • Scientists study endocytosis to understand how cells intake essential materials from their surroundings.

  • HCV infiltrates the cell through receptor-mediated endocytosis, probably via clathrin-coated pits.

  • How do we know endocytosis takes place?

  • We conclude that the primary role of ligand endocytosis is to generate mechanical force to activate Notch signaling.

  • We have developed techniques to depict receptor-mediated endocytosis of mt-GCR by the cells and tissues of patients with Gaucher's disease.

  • Beclin 1 can also regulate endocytosis and receptor recycling, crucial processes for growth factor signaling in neurons.

  • The studies also shed light on a new role for endocytosis to activate signaling in cells that is unique to Notch, said Laurence Meloty-Kapella, a post-doctoral researcher and first author of one of the studies.

  • However, this does not explain the abnormal excretion of low-molecular-weight proteins, which are specifically absorbed in the proximal tubule by endocytosis and transported in an acidic vacuolar-lysosomal system.

  • In one example of this mechanism, exosomes derived from SW480 colorectal cancer cells were effectively transferred and localized to the lysosomes of recipient HepG2 cells via dynamin-dependent endocytosis.

  • During endocytosis, a cell engulfs a nutrient molecule by wrapping its membrane around it.

A process where a cell surrounds and takes in tiny things like bacteria

is the specific membrane-based process of taking substances into a cell

Surface Forms

endocytosis singular
endocytoses plural

Morphology

endocytosis = cytosis (semi-transparent) = endo + cyt + osis

The prefix 'endo-' clearly indicates 'within', but the specific biological process might not be immediately clear to all learners.

Etymology

The word endocytosis comes from three parts: endo- 'inside', cyto- 'cell', and -osis 'process'. So endocytosis is the process of a cell surrounding and taking something inside itself.
