Mice were injected i.p. with IgG samples of different patients to test whether IgG from amyotrophic lateral sclerosis (ALS) can initiate an immune/inflammatory reaction targeting motor neurons. All IgG samples of five ALS patients and none of the disease controls recruited activated microglia cells in the ventral horn of the spinal cord. CD3 lymphocytes were not accumulated in the same tissue. ...

Alterations in the expression of the neuropeptide galanin were examined in micturition reflex pathways 6 weeks after complete spinal cord transection (T8). In control animals, galanin expression was present in specific regions of the gray matter in the rostral lumbar and caudal lumbosacral spinal cord, including: (1) the dorsal commissure; (2) the superficial dorsal horn; (3) the regions of the...

objective(s):spinal cord injury (sci) often causes serious and irreversible neurological deficit leading to disability or impairment of normal physical activity. atomoxetine, a selective norepinephrine transporter (net) inhibitor has gained much attention in the field of the neurodevelopmental disorder, but its effect on sci has not been evaluated. the present study has been undertaken to inves...

Objective(s): Glial cell line-derived neurotrophic factor (GDNF) can effectively promote axonal regeneration，limit axonal retraction，and produce a statistically significant improvement in motor recovery after spinal cord injury (SCI). However, the role in primate animals with SCI is not fully cognized. Materials and Methods:18 healthy juvenile rhesuses were divided randomly into six groups, obs...

The neonatal mouse en bloc spinal cord-brainstem preparation used in combination with advances in mouse genomics provides a novel strategy for studying the spinal control of locomotion. How well the mouse en bloc preparation is oxygenated however, is unknown. This is an important consideration given that (a) other superfused mammalian en bloc preparations have anoxic cores and (b) hypoxia can h...

a spinal cord injury (sci) refers to any injury to the spinal cord or nerves at the end of the spinal canal that is caused by trauma instead of disease often causes permanent changes in strength, sensation and other body functions below the site of the injury. road traffic collision (rtc) or car crash occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other...

Subclasses of motor neurons are generated at different positions along the rostrocaudal axis of the spinal cord. One feature of the rostrocaudal organization of spinal motor neurons is a position-dependent expression of Hox genes, but little is known about how this aspect of motor neuron subtype identity is assigned. We have used the expression profile of Hox-c proteins to define the source and...

Cell transplantation is a promising experimental treatment for spinal cord injury. The aim of the present study was to evaluate the efficacy of mononuclear cells from human umbilical cord blood in promoting functional recovery when transplanted after a contusion spinal cord injury. Female Wistar rats (12 weeks old) were submitted to spinal injury with a MASCIS impactor and divided into 4 groups...

Abstract In vertebrates, motor control relies on cholinergic neurons in the spinal cord that have been extensively studied over past hundred years, yet full heterogeneity of these and their different functional roles adult remain to be defined. Here, we developed a targeted single nuclear RNA sequencing approach used it identify an array interneurons, visceral skeletal neurons. Our dat...

BACKGROUND Calcium-activated chloride channels (CaCCs) activation induces membrane depolarization by increasing chloride efflux in primary sensory neurons that can facilitate action potential generation. Previous studies suggest that CaCCs family members bestrophin-1 and anoctamin-1 are involved in inflammatory pain. However, their role in neuropathic pain is unclear. In this investigation we a...
