A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane.

The directed movement of the hexose monosaccharide glucose into a cell or organelle.

The process whose specific outcome is the progression of the vasculature over time, from its formation to the mature structure. The vasculature is an interconnected tubular multi-tissue structure that contains fluid that is actively transported around the organism.

Any series of molecular signals in which a small monomeric GTPase relays one or more of the signals.

The directed movement of proteins into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

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

A series of molecular signals within the cell that are mediated by a member of the Rab family of proteins switching to a GTP-bound active state.

Cytoplasm situated near, or occurring around, the nucleus.

An organelle consisting of a network of tubules that functions in targeting molecules, such as receptors transporters and lipids, to the plasma membrane.

A small membrane-bounded vesicle that releases its contents by exocytosis in response to insulin stimulation; the contents are enriched in GLUT4, IRAP and VAMP2.

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

The lipid bilayer surrounding a secretory granule.

The lipid bilayer surrounding a cytoplasmic vesicle.

The lipid bilayer surrounding an early endosome.

Any small, fluid-filled, spherical organelle enclosed by membrane.

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.

A vacuole to which materials ingested by endocytosis are delivered.

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

Any small, fluid-filled, spherical organelle enclosed by membrane.

The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.

The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane.

A recycling endosome of the postsynapse. In postsynaptic terminals with dendritic spines, it is typically located at the base of a dendritic spine. It is involved in recycling of neurotransmitter receptors to the postsynaptic membrane. In some cases at least, this recycling is activated by postsynaptic signalling and so can play a role in long term potentiation.
