It paralyzes patients as it kills motor neurons in the brain and spinal cord. Researchers like Feldman believe stem cell therapiesoth from embryonic and adult varietiesight help patients grow new nerve cells.

and colleagues have developed an innovative method of generating high-yield and high-purity motor neurons from stem cells,

The researchers verified that the new motor neurons they obtained on soft micropost carpets showed electrical behaviors comparable to those of neurons in the human body.

The system was developed originally to improve the quality of life of individuals with severely impaired motor abilities such as those with motor neuron disease or cerebral palsy.

connects to the right motor neurons to allow movements like walking. The CPG is where relatively simple signals from the brain are translated into more complex instructions for motor neurons to control muscles.

But until now, researchers didn't know exactly how CPG cells forged connections with motor neurons. By tweaking the locations

and identities of motor neurons and then watching the resulting patterns of activation, researchers found that CPG cells didn't rely solely on motor neurons'locations to connect to them.

Instead, the genetic identity of each subtype of cells what makes those that control the quadriceps muscle different from those that control the calf muscle,

for instance is also important. That's a key finding for research on how to treat spinal cord injuries and ALS,

Current efforts involve stem cells that are transformed into motor neurons and then implanted into the spinal cord to regenerate damaged connections.

however, suggest that general motor neurons might not do the trick; specific subtypes of motor neurons may be necessary.

Funding for the work came from the National institutes of health, Howard Hughes Medical Institute, Christopher and Dana Reeve Foundation, Sol Goldman Trust and Marshall Heritage Foundation a

Motor neurons in the spinal cord can be seen in the researchers'images; at the same time, a single neuron with all its extensions is highlighted in another colour.

#New Hope for ALS Sufferers Researchers at the CHUM Research center and the University of Montreal report the discovery of a previously unknown link between the immune system and the death of motor neurons in Amyotrophic lateral sclerosis (ALS), also known as Lou gehrig's disease.

plays a critical role in the development of ALS. n imbalance of the immune system can contribute to the destruction of motor neurons

and destroys the animal's motor neurons, Dr. Parker explained. Is the same scenario at work with people?

particularly for new therapies to combat motor neuron disease. Here we show direct optogenetic stimulation of skeletal muscle from transgenic mice expressing the light-sensitive channel Channelrhodopsin-2 (Chr2.

The electromyography sensors-which could be used to directly control the glove work by detecting the residual muscle signals fired by motor neurons

#Immune system Linked to Motor neuron Death in ALS A previously unknown link between the immune system and the death of motor neurons in Amyotrophic lateral sclerosis (ALS),

a tiny 1 mm-long roundworm, plays a critical role in the development of ALS. n imbalance of the immune system can contribute to the destruction of motor neurons

and destroys the animal motor neurons, Alex Parker explained. Is the same scenario at work with people?

Here we show that the expression of mutant proteins causative for ALS in Caenorhabditis elegans motor neurons induces an innate immune response via TIR-1/Sarm1.

and the transcription factor atf-7 all suppress motor neuron degeneration. The neurosecretory proteins UNC-13 and UNC-31 are required for induction of the immune response as well as the degeneration of motor neurons.

The human orthologue of UNC-13 UNC13A, has been identified as a genetic modifier of survival in ALS,

and we provide functional evidence of UNC-13/UNC13A in regulating motor neuron degeneration. We propose that the innate immune system reacts to the presence of mutant proteins as a contagion,
