In Vitro Models for Studying the Interaction of Neisseria meningitidis with Human Brain Endothelial Cells
2019
: Bacterial meningitis is a serious, life-threatening infection of the central nervous system (CNS). To cause meningitis, bacteria must interact with and penetrate the meningeal blood-cerebrospinal fluid barrier (mB/CSFB), which comprises highly specialized brain endothelial cells. Neisseria meningitidis (meningococcus) is a leading cause of bacterial meningitis, and examination meningococcus' interaction with the BBB is critical for understanding disease progression. To examine specific interactions, in vitro mB/CSFB models have been developed and employed and are of great importance because in vivo models have been difficult to produce considering Neisseria meningitidis is exclusively a human pathogen. Most in vitro blood-brain barrier and mB/CSF models use primary and immortalized brain endothelial cells, and these models have been used to examine bacterial-mB/CSFB interactions by a variety of pathogens. This chapter describes the use of past and current in vitro brain endothelial cells to model Neisseria meningitidis interaction with the mB/CSFB, and inform on the standard operating procedure for their use.
