Pinocytosis. In cellular biology, pinocytosis, otherwise known as fluid endocytosis and bulk-phase pinocytosis, is a mode of endocytosis in which small molecules dissolved in extracellular fluid are brought into the cell through an invagination of the cell membrane, resulting in their containment within a small vesicle inside the cell.
Here, both infectious forms of VACV, mature virion (MV) and enveloped virion (EV), induce their own macropinocytosis by binding to the cell surface and triggering an actin-mediated plasma membrane protrusion that eventually collapses back onto the plasma membrane sealing the attached virion inside a macropinosome, which then goes through a ...
The different types of endocytosis. Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested materials.

Cosimo Commisso is a Canadian cell biologist and cancer researcher who has made significant advances in the field of cellular trafficking and cancer metabolism. [1] [2] [3] Among his most notable contributions are the discovery and study of how macropinocytosis supports tumor cell growth and survival by serving as an amino acid supply route in Ras-mutated cancers.
In cell biology, efferocytosis (from efferre, Latin for 'to carry out' [1] (to the grave), extended meaning 'to bury') is the process by which apoptotic cells are removed by phagocytic cells. It can be regarded as the 'burying of dead cells'.
Bleb growth is driven by intracellular pressure (abnormal growth) generated in the cytoplasm when the actin cortex undergoes actomyosin contractions. [5] The disruption of the membrane-actin cortex interactions [4] are dependent on the activity of myosin-ATPase [6] Bleb initiation is affected by three main factors: high intracellular pressure, decreased amounts of cortex-membrane linker ...
Microcytic anaemia; Microcytosis is the presence of red cells that are smaller than normal. Normal adult red cell has a diameter of 7.2 µm. Microcytes are common seen in with hypochromia in iron-deficiency anaemia, thalassaemia trait, congenital sideroblastic anaemia and sometimes in anaemia of chronic diseases.
