The directed movement of a motile cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).

The aggregation, arrangement and bonding together of a set of components to form a podosome, an actin-rich adhesion structure characterized by formation upon cell substrate contact and localization at the substrate-attached part of the cell.

A membrane tubulation process occurring in a plasma membrane.

A vesicle-mediated transport process in which cells take up external materials or membrane constituents by the invagination of a small region of the plasma membrane to form a new membrane-bounded vesicle.

The internalization of bacteria, immune complexes and other particulate matter or of an apoptotic cell by phagocytosis, including the membrane and cytoskeletal processes required, which involves one of three mechanisms: zippering of pseudopods around a target via repeated receptor-ligand interactions, sinking of the target directly into plasma membrane of the phagocytosing cell, or induced uptake via an enhanced membrane ruffling of the phagocytosing cell similar to macropinocytosis.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the nucleus.

The vesicular release of classical neurotransmitter molecules from a neuron, across a chemical synapse, the subsequent activation of neurotransmitter receptors of a target cell (neuron, muscle, or secretory cell) and the effects of this activation on the postsynaptic membrane potential and ionic composition of the postsynaptic cytosol. This process encompasses both spontaneous and evoked release of neurotransmitter and all parts of synaptic vesicle exocytosis. Evoked transmission starts with the arrival of an action potential at the presynapse.

Any process in an organism in which a relatively long-lasting adaptive behavioral change occurs as the result of experience.

The regulated exocytosis of secretory granules containing preformed mediators such as proteases, lipases, and inflammatory mediators by a neutrophil.

Any process that activates or increases the activity of a GTPase.

Any process that activates or increases the frequency, rate or extent of endocytosis.

Clathrin-mediated endocytosis of presynaptic membrane that recycles synaptic vesicle membrane and its components following synaptic vesicle exocytosis. This process starts with coating of the membrane with adaptor proteins and clathrin prior to invagination and ends when uncoating has finished.

Any process in which the nucleus is transported to, and/or maintained in, a specific location within the cell.

Muscle contraction of cardiac muscle tissue.

The directed movement of a motile cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).

The aggregation, arrangement and bonding together of a set of macromolecules to form a macromolecular complex that contains a tube of lipid surrounded by a protein coat involved in membrane shaping of vesicle membranes as organelles undergo fission.

A process which results in the assembly, arrangement of constituent parts, or disassembly of a membrane. A membrane is a double layer of lipid molecules that encloses all cells, and, in eukaryotes, many organelles; may be a single or double lipid bilayer; also includes associated proteins.

The aggregation, arrangement and bonding together of a set of components to form a podosome, an actin-rich adhesion structure characterized by formation upon cell substrate contact and localization at the substrate-attached part of the cell.

A membrane tubulation process occurring in a plasma membrane.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

A secretory organelle, typically 50 nm in diameter, of presynaptic nerve terminals; accumulates in high concentrations of neurotransmitters and secretes these into the synaptic cleft by fusion with the 'active zone' of the presynaptic plasma membrane.

The specialized, terminal region of a neuron projection such as an axon or a dendrite.

An actin-rich adhesion structure characterized by formation upon cell substrate contact and localization at the substrate-attached part of the cell, contain an F-actin-rich core surrounded by a ring structure containing proteins such as vinculin and talin, and have a diameter of 0.5 mm.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

The double lipid bilayer enclosing the nucleus and separating its contents from the rest of the cytoplasm; includes the intermembrane space, a gap of width 20-40 nm (also called the perinuclear space).

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The part of the cytoskeleton (the internal framework of a cell) composed of actin and associated proteins. Includes actin cytoskeleton-associated complexes.

The portion of the plasma membrane surrounding the leading edge of a motile cell.

The portion of the plasma membrane surrounding the leading edge of a motile cell.
