Once transplanted, these cells can proliferate, differentiate, and often completely replace the cells of the host in both the germline and/or somatic tissues. These processes are called germ cell parasitism (gcp), or somatic cell parasitism (scp), respectively, and we have shown that there are...
The density of nodes of Ranvier was examined at CNS, PNS, and transitional zone (TZ) levels of rat lumbar ventral motoneurone fibres. It was found to be significantly greater in the TZ than at the other levels: The difference was sevenfold for the ventral root and at least fourfold for...

Through systematic quantification of ZIKV infected cells in myelinating cultures, we found that ZIKV infection is enhanced in the absence of the type I interferon responses and that CNS cells are considerably more susceptible to infection than PNS cells. In particular, we demonstrate that CNS axons...
the voltage difference across a membrane Resting potential the state of the neuron when not firing a neural impulse hyper-polarization membrane potential becomes more negative action potential the change in electrical potential associated with the passage of an impulse along the membrane of a muscle ce...
What is the difference in function between CNS gray matter and CNS white matter? Where are these tissues located in the brain and spinal cord? What structure is found surrounding axons in both the CNS and the PNS? a. myelin sheath b. neurilemma c. Nodes of Ranvier d. plasma membrane e...
Schwann cell grafts support axonal growth following spinal cord injury, but a boundary forms between the implanted cells and host astrocytes. Axons are reluctant to exit the graft tissue in large part due to the surrounding inhibitory environment contain
tend to block the changes that cause an action potential to be generated in a postsynaptic neuron. neuromodulators can diffuse to another synapse and are a type of NT. what is the difference between neurotransmitters and neuromodulators?
Compare the CNS and the PNS. The Nervous System: The nervous system is the body's main integrating system that specializes in communication between the body and the brain. The two main divisions of the nervous system include the central nervous system (CNS) and the peripheral nervous system (...
As a result, downregulation of Lin28a/b or upregulation of let-7a resulted in reduced sensory axon regeneration in vitro and in vivo. Conversely, overexpression of Lin28a or Lin28b or inhibition of let-7 miRNAs enhanced PNS sensory axon regeneration in vivo. Most importantly, we showed that...
