The function of the immunological barrier in the epididymis is to protect the sperm from attack by the immune system. Primarily, this function is carried out by the BEB, which sequesters sperm antigens and restricts entry of immunoglobulins and immune cells (Fig. 2 B).
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.he blood-brain barrier (BBB) is a diffusion barrier, which impedes influx of most compounds from blood to brain.
