One of the least understood issues in the pathogenesis and pathophysiology of microbial infection of the central nervous system (CNS) is how microorganisms cross the blood-brain barrier (BBB), which separates brain interstitial space from blood and is formed by the tight junctions of brain microvascular endothelial cells (BMEC). BMEC monolayer and bilayer culture systems have been developed as in vitro models to dissect the mechanisms of adhesion and invasion involved in pathogenesis of CNS infection caused by microbes. Viral, bacterial, fungal and parasitic pathogens may breach the BBB and enter the CNS through paracellular, transcellular and/or Trojan horse mechanisms. Conceivable evidence suggests that microbial proteins are the major genetic determinants mediating penetration across the BBB. Several bacterial proteins including IbeA, IbeB, AslA,YijP, OmpA, PilC and InlB contribute to transcellular invasion of BMEC. Viral proteins such as gp120 of HIV have been shown to play a role in penetration of the BBB. Fungal and parasitic pathothogens may follow similar mechanisms. SAG1 of Toxoplasma gondii has been suggested as a ligand to mediate host-cell invasion. Understanding the fundamental mechanisms of microbial penetration of the BBB may help develop novel approaches to prevent the mortality and morbidity associated with central nervous system (CNS) infectious diseases.
