Myelin basic protein (MBP) is a protein believed [weasel words] to be important in the process of myelination of nerves in the nervous system. The myelin sheath is a multi-layered membrane, unique to the nervous system, that functions as an insulator to greatly increase the velocity of axonal impulse conduction . [ 5 ]
A cholinergic neuron is a nerve cell which mainly uses the neurotransmitter acetylcholine (ACh) to send its messages. Many neurological systems are cholinergic.Cholinergic neurons provide the primary source of acetylcholine to the cerebral cortex, and promote cortical activation during both wakefulness and rapid eye movement sleep.

Cholinergic treatments, such as acetylcholinesterase inhibitors (AChEIs), may have beneficial effects on myelination, myelin repair, and myelin integrity. Increasing cholinergic stimulation also may act through subtle trophic effects on brain developmental processes and particularly on oligodendrocytes and the lifelong myelination process they ...
Prion protein triggers are an important factor in the signals that ensure myelin maintenance and are distinct from those that direct myelination. Prion protein and antibodies POM1 and POM3, which recognize epitopes in the terminus (around amino acids (aa) 140–152) and charged clusters of prion protein (aa95-100) were used to their role in ...
Myelin is formed by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system.Therefore, the first stage of myelinogenesis is often defined as the differentiation of oligodendrocyte progenitor cells (OPCs) or Schwann cell progenitors into their mature counterparts, [4] followed by myelin formation around axons.
Choline acetyltransferase was first described by David Nachmansohn and A. L. Machado in 1943. [6] A German biochemist, Nachmansohn had been studying the process of nerve impulse conduction and utilization of energy-yielding chemical reactions in cells, expanding upon the works of Nobel laureates Otto Warburg and Otto Meyerhof on fermentation, glycolysis, and muscle contraction.

The nucleus basalis in humans is a somewhat diffuse collection of large cholinergic neurons in the basal forebrain. [2] The main body of the nucleus basalis lies inferior to the anterior commissure and the globus pallidus , and lateral to the anterior hypothalamus in an area known as the substantia innominata .
