The damaged neurons may be replaced by other cells in an effort to reverse the neurodegeneration. These cells often have a higher iron content. The breakdown of the blood brain barrier may also occur due to the loss of neurons and will subsequently allow more iron to access the brain and accumulate over time. [3]
Tay–Sachs disease is an inherited lysosomal storage disease that results in the destruction of nerve cells in the brain and spinal cord. [1] The most common form is infantile Tay–Sachs disease, which becomes apparent around the age of three to six months of age, with the infant losing the ability to turn over, sit, or crawl. [1]
Ependymal cells, also named ependymocytes, line the spinal cord and the ventricular system of the brain. These cells are involved in the creation and secretion of cerebrospinal fluid (CSF) and beat their cilia to help circulate the CSF and make up the blood-CSF barrier. They are also thought to act as neural stem cells. [15] CNS: Radial glia
Oligodendrocytes are a type of glial cell, non-neuronal cells in the central nervous system.They arise during development from oligodendrocyte precursor cells (OPCs), [8] which can be identified by their expression of a number of antigens, including the ganglioside GD3, [9] [10] [11] the NG2 chondroitin sulfate proteoglycan, and the platelet-derived growth factor-alpha receptor subunit (PDGF ...
The blood–brain barrier (BBB) is a highly selective semipermeable border of endothelial cells that regulates the transfer of solutes and chemicals between the circulatory system and the central nervous system, thus protecting the brain from harmful or unwanted substances in the blood. [1]

Ribose-5-phosphate isomerase deficiency (RPID) is a rare human disorder caused by mutations in ribose-5-phosphate isomerase, an enzyme of the pentose phosphate pathway.With only four known cases – all diagnosed between 1984 and 2019 – RPI deficiency is the second rarest disease, with Fields condition being the rarest, affecting two known individuals, Catherine and Kirstie Fields.
