The present invention relates to the treatment of infectious diseases. In this study, we identify potential defense mechanisms involved in maintaining brain vascular integrity during bacterial infection and perform RNA analysis of primary endothelial cells isolated from human skin (HDMEC) or brain (HBMEC) microvessels. The cells were either uninfected or infected with Neisseria meningitidis in vitro. We found 40 genes, especially ANGPTL4, that are specifically regulated in brain endothelial cells during infection. In the context of sepsis, ANGPTL4 was found to be the main barrier stabilizing protein with a defensive effect against bacterial infection. ANGPTL4 (or derived peptides) also showed potential as an adjunctive therapy to reduce bacteria-induced vascular dysfunction and mortality. Thus, the present invention relates to peptides derived from the protein ANGPTL4 and their use in the treatment of infectious diseases.
