Tryptase (EC 3.4.21.59) is the most abundant secretory granule-derived serine proteinase contained in mast cells and has been used as a marker for mast cell ...
Cell motility involves many receptors, crosslinking, bundling, binding, adhesion, motor and other proteins. [16] The process is divided into three steps: protrusion of the leading edge of the cell, adhesion of the leading edge and de-adhesion at the cell body and rear, and cytoskeletal contraction to pull the cell forward.
In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function. The name organelle comes from the idea that these structures are parts of cells, as organs are to the body , hence organelle, the suffix -elle being a diminutive .
Cell physiology is the biological study of the activities that take place in a cell to keep it alive. The term physiology refers to normal functions in a living organism. [1] Animal cells, plant cells and microorganism cells show similarities in their functions even though they vary in structure. [2] [page needed]
The cytoskeleton maintains the nuclear components of a cell and the size of the cell body in neurons. The increase in protein within the neuron leads to this change in the cytoskeleton. For example, there is an increase in phosphorylated neurofilament proteins and cytoskeletal components, tubulin and actin , in neurons undergoing chromatolysis ...
Goblet cells are simple columnar epithelial cells, having a height of four times that of their width. The cytoplasm of goblet cells tends to be displaced toward the basal end of the cell body by the large mucin granules, which accumulate near the apical surface of the cell along the Golgi apparatus, which lies between the granules and the nucleus.
In biology, cell signaling (cell signalling in British English) is the process by which a cell interacts with itself, other cells, and the environment. Cell signaling is a fundamental property of all cellular life in prokaryotes and eukaryotes. Typically, the signaling process involves three components: the signal, the receptor, and the effector.
Its primary function is to give the cell its shape and mechanical resistance to deformation, and through association with extracellular connective tissue and other cells it stabilizes entire tissues. [ 4 ] [ 5 ] The cytoskeleton can also contract, thereby deforming the cell and the cell's environment and allowing cells to migrate . [ 6 ]
