A protein complex which mediates interferon-gamma-induced transcript-selective translation inhibition in inflammation processes. The complex binds to stem loop-containing GAIT elements in the 3'-UTR of diverse inflammatory mRNAs and suppresses their translation by blocking the recruitment of the 43S ribosomal complex to m7G cap-bound eIF4G. In humans it includes RPL13A, EPRS, SYNCRIP and GAPDH; mouse complexes lack SYNCRIP.

Portion of the ensheathing process (either myelin or non-myelin) where the enveloping lips of the ensheathing cell come together so that their apposed plasma membranes run parallel to each other, separated by a cleft 12 nm wide.

Small finger-like extension of a Schwann cell that contacts the nodal membrane.

A prolongation or process extending from a glial cell.

Thin cylindrical membrane-covered projections on the surface of an animal cell containing a core bundle of actin filaments. Present in especially large numbers on the absorptive surface of intestinal cells.

Paranodal terminations of Schwann cells that do not directly contact the paranodal axon membrane. Usually found in thicker myelin.

Portion of myelin-forming Schwann cell consisting of terminal cytoplasmic extensions adhered to the axon at the beginning and end of the myelin sheath.

Axon of dentate gyrus granule cell projecting to hippocampal area CA3, characterized by expansions (mossy fiber expansions) giving the fibers a mossy appearance. These unmyelinated axons were first described by Ramon y Cajal.

OBSOLETE. Any constituent part of a neuron, the basic cellular unit of nervous tissue. A typical neuron consists of a cell body (often called the soma), an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the nervous system.

Elongated neuronal process, often with side branches and more than one branching point, described in brains of patients with Parkinson's disease. Lewy neurites stain positively for ubiquitin in brainstem and forebrain regions affected in Parkinson's disease.

Spine-like process found on some neurons, e.g., periglomerular cells of olfactory cortex.

Large complex spine protruding from a dendrite. Each excrescence is formed by a cluster of spine heads.

A small, membranous protrusion from a dendrite that forms a postsynaptic compartment, typically receiving input from a single presynapse. They function as partially isolated biochemical and an electrical compartments. Spine morphology is variable:they can be thin, stubby, mushroom, or branched, with a continuum of intermediate morphologies. They typically terminate in a bulb shape, linked to the dendritic shaft by a restriction. Spine remodeling is though to be involved in synaptic plasticity.

Spine emanating from the cell soma of a neuron.

An ERAD pathway whereby endoplasmic reticulum (ER)-resident glycoproteins are targeted for degradation. Includes differential processing of the glycoprotein sugar chains, retrotranslocation to the cytosol and degradation by the ubiquitin-proteasome pathway. A glycoprotein is a compound in which a carbohydrate component is covalently bound to a protein component.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a glycoprotein stimulus.

The series of steps necessary to target endoplasmic reticulum (ER)-resident proteins for degradation by the cytoplasmic proteasome. Begins with recognition of the ER-resident protein, includes retrotranslocation (dislocation) of the protein from the ER to the cytosol, protein ubiquitination necessary for correct substrate transfer, transport of the protein to the proteasome, and ends with degradation of the protein by the cytoplasmic proteasome.
