Astrocytes are star-shaped neuroglia that form the blood brain barrier between blood vessels and neurons.

Astrocytes anchor neurons to blood vessels!
Another side effect of sickle cell disease is the tendency for sickle-shaped red blood cells to get stuck in blood vessels, leading to blockages that can cause pain, organ damage, and even stroke.
The most abundant type of macroglial cell, astrocytes(also called astroglia) have numerous projections that anchor neurons to their blood supply.Read more: glial-cell
Not all cells are ball-shaped; they come in various shapes depending on their function and type. For example, red blood cells are typically disc-shaped, while neurons have long, branching structures. Bacteria can be spherical (cocci), rod-shaped (bacilli), or spiral (spirilla). The shape of a cell is often adapted to its specific role in an organism.
Could one conclude that Ependymal cells & Oligodenrocytes blood cells in the CNS protects neurons from some blood substances in blood.
yes
Astrocytes. They provide physical and metabolic support to neurons in the central nervous system, participate in neurotransmitter uptake and recycling, and help maintain the blood-brain barrier.
some of the drugs can cross blood-brain barrier, so it can affect neurons too.
