The paracellular transport occurs by passive diffusion through the TJs, while the transcellular transport pathway occurs via the BECs per se ( Paracellular Pathway The paracellular pathway occurs between cells by the passive diffusion of low molecular mass hydrophilic molecules ( Transcellular Pathway Transcellular Diffusion Transcellular diffusion takes place at the luminal and abluminal membrane of BECs ( 2 and CO 2 ( Carrier-Mediated Transport CMT can either be active or passive ( via substrate-specific transporters ( Receptor-Mediated Transcytosis RMT is the main pathway used for the uptake of molecules that do not possess a specific carrier ( Efflux Transport Efflux pumps are responsible for the removal of substances out of the CNS into the systemic circulation in order to prevent the accumulation of compounds that have gone through the BBB ( Adsorptive Transcytosis Adsorptive transcytosis relies on the non-specific transport of positively charged substrates, such as cationized albumin, when they react with the negatively charged surface of BECs ( After briefly reviewing the physiological functions of BBB and NVU, it is clear that the strict regulation of the BBB plays a fundamental contribution to the maintenance of brain homeostasis, triggering a vast number of pathological consequences when any of its components is altered ( BloodBrain Barrier and Stroke A total of 14 million people suffer from stroke worldwide

Vitamin B 12 deficiency, like folate deficiency, may lead to decreased synthesis of methionine and S-adenosylmethionine (SAM), thereby adversely affecting methylation reactions
