Generation of functional neurons from adult human mucosal olfactory ensheathing glia by direct lineage conversion [PDF]

Cell Death and Disease, 2023
A recent approach to promote central nervous system (CNS) regeneration after injury or disease is direct conversion of somatic cells to neurons. This is achieved by transduction of viral vectors that express neurogenic transcription factors. In this work

Olfactory ensheathing glia are required for embryonic olfactory axon targeting and the migration of gonadotropin-releasing hormone neurons [PDF]

Biology Open, 2013
Summary Kallmann's syndrome is caused by the failure of olfactory axons and gonadotropin-releasing hormone (GnRH) neurons to enter the embryonic forebrain, resulting in anosmia and sterility.

Differential response of injured and healthy retinas to syngeneic and allogeneic transplantation of a clonal cell line of immortalized olfactory ensheathing glia: a double-edged sword [PDF]

Neural Regeneration Research
Olfactory ensheathing glia promote axonal regeneration in the mammalian central nervous system, including retinal ganglion cell axonal growth through the injured optic nerve.

Small molecules fail to induce direct reprogramming of adult rat olfactory ensheathing glia to mature neurons [PDF]

Frontiers in Molecular Neuroscience, 2023
An approach to generate new neurons after central nervous system injury or disease is direct reprogramming of the individual's own somatic cells into differentiated neurons.

Activation of cannabinoid type 1 receptor (CB1) modulates oligodendroglial process branching complexity in rat hippocampal cultures stimulated by olfactory ensheathing glia-conditioned medium [PDF]

Frontiers in Cellular Neuroscience, 2023
The endocannabinoid system (ECS) refers to a complex cell-signaling system highly conserved among species formed by numerous receptors, lipid mediators (endocannabinoids) and synthetic and degradative enzymes. It is widely distributed throughout the body

Olfactory ensheathing cells from adult female rats are hybrid glia that promote neural repair

eLife, 2023
Olfactory ensheathing cells (OECs) are unique glial cells found in both central and peripheral nervous systems where they support continuous axonal outgrowth of olfactory sensory neurons to their targets.

Olfactory ensheathing glia express aquaporin 1. [PDF]

J Comp Neurol, 2010
AbstractOlfactory ensheathing glia (OEG) are distinct from other glia in their developmental origin, presence in both the peripheral and central nervous systems, and highly restricted location. OEG are present only in the olfactory lamina propria, olfactory nerve, and the outer two layers of the olfactory bulb, where they envelop bundles of olfactory ...

A role for gangliosides and β1‐integrin in the motility of olfactory ensheathing glia [PDF]

Journal of Anatomy, 2019
Olfactory ensheathing glia (OEG) are found in the olfactory mucosa, nerve and bulb, and provide in vivo ensheathment for the unmyelinated olfactory axons within the central and peripheral nervous system domains.

Neural crest origin of olfactory ensheathing glia. [PDF]

Proc Natl Acad Sci U S A, 2010
Olfactory ensheathing cells (OECs) are a unique class of glial cells with exceptional translational potential because of their ability to support axon regeneration in the central nervous system. Although OECs are similar in many ways to immature and nonmyelinating Schwann cells, and can myelinate large-diameter axons indistinguishably from myelination ...

Olfactory ensheathing cells for spinal cord repair: crucial differences between subpopulations of the glia

Neural Regeneration Research, 2015
OECs for spinal cord repair: Is repairing the injured spinal cord by olfactory ensheathing cell (OEC) transplantation possible? A recent human trial in which a paralysed man regained some function after transplantation of partially purified OECs suggests
