For instance, Group B <jats:italic>Streptococcus<\/jats:italic> (GBS) chorioamnionitis generates autistic manifestations in the progeny. However, the precise way(s) how chorioamnionitis exerts its noxious effect on the central nervous system remains to be define. The pathogen-induced inflammatory response effects on the permeability of the blood brain barrier (BBB) have been documented in the mature brain. No study deals with the effect of GBS-induced chorioamnionitis, on the fetal BBB, even though it is one of the most common infection affecting the fetal environment. Given that dysfunctions of several key cells and molecules from the BBB seem to be involved in the pathogenesis of ASD from genetic and\/or environmental origins, we hypothesized that pathogen-induced chorioamnionitis affects structurally and functionally the BBB. We used a well-established preclinical model of GBS chorioamnionitis leading to ASD phenotype in male offspring. We document a significant decrease of albumin permeability of the BBB in the white and gray matters of fetuses exposed <jats:italic>versus<\/jats:italic> unexposed to GBS chorioamnionitis. In line with this result, a significant increase in the expression of claudin-5 \u2013 component of tight junctions of the BBB \u2013 is detected in endothelial cells from BBB exposed to chorioamnionitis. Altogether, our results show that beyond genetic determinants, environmental factors such as bacterial infections affect the integrity of the BBB and might be involved in the fetal programming of ASD.<\/jats:p>","DOI":"10.1017\/s2040174425100147","type":"journal-article","created":{"date-parts":[[2025,8,1]],"date-time":"2025-08-01T08:48:39Z","timestamp":1754038119000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":1,"title":["Restricted
