Abstract:
The efficient and selective removal of apoptotic cells is an important feature of tissue development, homeostasis and pathology. In the nervous system, synapses and distal axons are selectively eliminated as part of the remodelling that underpins development and pathology, through a process that has some features in common with apoptotic cell removal. Components of the complement cascade are implicated in the efficient removal of apoptotic cells outside the nervous system, and recent evidence suggests that the complement components C1q and C3 have a role in the selective tagging of supernumerary synapses in the developing visual system and in their efficient removal by as yet unidentified cells.

Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Synaptic Signaling
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.
The presynaptic neuron fires an action potential that...
