The bloodâbrain barrier (BBB) is a highly selective permeability barrier that separates the circulating blood from the brain extracellular fluid (BECF) in the central nervous system (CNS).t is believed that latent HIV can cross the bloodâbrain barrier inside circulating monocytes in the bloodstream ( Trojan horse theory) within the first 14 days of infection. Once inside, these monocytes become activated and are transformed into macrophages.
