Intermediate Filaments of Schwann Cells

Journal of Neurochemistry, 1982
Abstract: Intermediate filaments were prepared from distal stumps of rabbit sciatic nerve 5 weeks after nerve section, at which time Schwann cells account for 85–90% of the cell area. A polypeptide of molecular weight 58,000 was the main component of this fraction. An antiserum raised in guinea pig against this polypeptide stained all cells present in

Mechanism of phagocytosis by Schwann cells

Journal of the Neurological Sciences, 1986
33B rat Schwannoma cell line is known to exhibit phagocytic properties analogous to those of normal Schwann cells. The mechanism of phagocytosis by this cell line was investigated by studying the effect of known modulators of phagocytosis on the uptake of latex particles by these cells. Treatments which block energy production of the host cell, such as

Immunomodulation by Schwann cells in disease

Cancer Immunology, Immunotherapy, 2019
Schwann cells are the principal glial cells of the peripheral nervous system which maintain neuronal homeostasis. Schwann cells support peripheral nerve functions and play a critical role in many pathological processes including injury-induced nerve repair, neurodegenerative diseases, infections, neuropathic pain and cancer.

Schwann cell energy to die for

Nature Neuroscience, 2020
A new study shows that, immediately after axon injury, glycolysis is increased in Schwann cells to provide axons with energy and prevent them from degenerating. The authors also identify possible therapeutic targets that could be modulated to promote axonal protection.

Rhythmic Contraction of Schwann Cells [PDF]

Science, 1959
By time-lapse cinematography it was found that Schwann cells in tissue cultures of dorsal root ganglia from newborn rats show a contraction rate of approximately 4 to 18 minutes. This activity is of the order of magnitude reported for oligodendroglia.

Cytokine and chemokine interactions with Schwann cells: the neuroimmunology of Schwann cells

2007
INTRODUCTION Cytokines, first described as products of the cells of the inflammatory/immune system, are increasingly recognised as acting on non-inflammatory cells as well as being produced by non-inflammatory cells. Nowhere is this more apparent than with cells of the peripheral (PNS) and central (CNS) nervous systems.

Developmental Regulation of Schwann Cell Precursors and Schwann Cell Generation

1997
Most myelin-forming and non-myelin-forming Schwann cells of peripheral nerves develop from the neural crest (Anderson, 1993; Bronner-Fraser, 1993; Jessen and Mirsky, 1992; Le Douarin et al., 1991; Marusich and Weston, 1991). The other main glial types in the peripheral nervous system (PNS), are also thought to be derived from the crest.

Schwann Cells in Phylogeny [PDF]

, 2003
Schwann cells are the nonneuronal cells that ensheath peripheral axons. Brought to prominence by Theodor Schwann in 1839 these cells have, until recently, been considered to be relatively passive components of the nerve, apart from their vital role in providing myelin sheaths around the larger axons.

Schwann cell precursors and their development

Glia, 1991
AbstractDuring development of peripheral nerves, an apparently homogeneous pool of embryonic Schwann cells gives rise to two morphologically and antigenically distinct mature Schwann cell types. These are the myelin‐forming cells associated with axons of larger diameter and the non‐myelin‐forming cells associated with axons of smaller diameter.The ...

Schwann cell growth factors

Cell, 1978
Purified rat Schwann cells were found to proliferate very slowly in normal growth medium containing 10% fetal calf serum (FCS). Crude extracts of bovine pituitary or brain markedly enhanced Schwann cell growth, while similar extracts of nerve roots, liver and kidney did not.
