Understanding the mechanisms of in penetrating the blood-brain barrier: insights into bacterial binding with central nervous system host receptors.

This review investigates the pathogenic processes through which crosses the blood-brain barrier (BBB) to cause meningitis, with a focus on the interaction with host receptors in the central nervous system (CNS). a primary cause of bacterial meningitis, utilizes unique receptor-mediated pathways to infiltrate the BBB. The bacterial interaction with the platelet-activating factor receptor (PAFR) and the polymeric immunoglobulin receptor (pIgR) is looked at in this study. The goal is to understand how this interaction helps the bacterium move across the BBB and cause infection in the CNS. We examine the functions of cellular and molecular participants at the endothelium level, such as cytokines, chemokines, and matrix metalloproteinases (MMP), which have a role in the development of the disease. This study consolidates data from multiple studies, providing a thorough summary of the interactions between and the BBB. It also explores potential treatment targets that could reduce the significant illness and death rates associated with pneumococcal meningitis.
