In the brain, neurons are separated from the blood by the blood-brain barrier.

Neurons are separated from blood-borne substances by the blood-brain barrier (BBB), which is a highly selective semipermeable barrier formed by specialized endothelial cells in the blood vessels of the brain. These endothelial cells have tight junctions that prevent most substances in the blood from freely crossing into the brain. The BBB allows only certain molecules, such as oxygen and nutrients, to pass through while keeping out potentially harmful substances, like toxins and pathogens.

Neuroglial cells that helps form the blood brain barrier?
The blood-brain barrier (BBB) is a diffusion barrier, which impedes influx of most compounds from blood to brain. Three cellular elements of the brain microvasculature compose the BBB-endothelial cells, astrocyte end-feet, and pericytes (PCs). Tight junctions (TJs), present between the cerebral endothelial cells, form a diffusion barrier, which selectively excludes most blood-borne substances from entering the brain. Astrocytic end-feet tightly ensheath the vessel wall and appear to be critical for the induction and maintenance of the TJ barrier, but astrocytes are not believed to have a barrier function in the mammalian brain.Read more: What_is_the_structure_of_blood_brain_barrier
