Cancer cells as well as bacteria metastasize to the subarachnoidal space (SAS) causing meningitis. Primary brain tumors, although not forming distant metastases, disseminate via the cerebrospinal fluid and occupy the meninges. The multistep process of cancer or bacterial dissemination is regulated through molecular crosstalk between invaders and host cells. Such crosstalks establish invasion-promoter and invasion-suppressor complexes. In carcinomatous and bacterial meningitis, the participation of host cells is prominent since leukocytes and inflammatory cytokines are the major determinants of malignancy. We propose a model in which bacterial breakdown products activate endothelial cells, a process leading to leukocyte extravasation. This initiates a cascade of inflammatory processes opening up the blood cerebrospinal fluid barrier and producing access for new invaders.
