A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died.

Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat.

An intracellular protein kinase cascade containing at least a JNK (a MAPK), a JNKK (a MAPKK) and a JUN3K (a MAP3K). The cascade can also contain an additional tier: the upstream MAP4K. The kinases in each tier phosphorylate and activate the kinases in the downstream tier to transmit a signal within a cell.

The multiplication or reproduction of glial cells by cell division, resulting in the expansion of their population. Glial cells exist throughout the nervous system, and include Schwann cells, astrocytes, and oligodendrocytes among others.

The blackening of the wounded area of the cuticle or the surface of invading pathogens, parasites or parasitoids, resulting from a proteolytic cascade leading to the de novo synthesis and deposition of melanin.

The removal of the apoptotic cell by phagocytosis, by a neighboring cell or by a phagocyte.

Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.

Any process in which a protein is transported to, or maintained in, a specific asymmetric distribution, resulting in the formation of daughter cells of different types.

Any process in which a protein is transported to, or maintained in, apical regions of the cell.

Reactions triggered in response to the presence of a Gram-negative bacterium that act to protect the cell or organism.

The cellular homeostatic process that preserves a neuron in a stable, differentiated functional and structural state.

A series of molecular signals in which a signal is conveyed from the cell surface to trigger the apoptotic death of a cell. The pathway starts with either a ligand binding to a cell surface receptor, or a ligand being withdrawn from a cell surface receptor (e.g. in the case of signaling by dependence receptors), and ends when the execution phase of apoptosis is triggered.

Any process that stops, prevents or reduces the frequency, rate or extent of neuromuscular synaptic transmission.

Any process that activates or increases the frequency, rate or extent of sensory perception of pain.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The component of the plasma membrane consisting of gene products and protein complexes that have some part that spans both leaflets of the membrane.
