There are still significant knowledge gaps in understanding the intrusion and retention of exogeneous particles into the central nervous system (CNS). Here, we uncovered various exogeneous fine particles in human cerebrospinal fluids (CSFs) and identified the ambient environmental or occupational exposure sources of these particles, including commonly found particles (e.g., Fe- and Ca-containing ones) and …

Identification of a choroid plexus vascular barrier closing during #intestinal inflammation
Locking down access to the brainInflammatory bowel disease is best known for intestinal symptoms but can also cause a variety of extraintestinal manifestations in other organs. It can also be associated with cognitive and psychiatric effects, including anxiety and depression. Using mouse models of intestinal inflammation, Carloni et al. uncovered a potential pathogenic link between …
#Disruption of the blood−brain barrier in 22q11.2 deletion syndrome
Neuroimmune dysregulation is implicated in neuropsychiatric disorders including schizophrenia. As the blood−brain barrier is the immunological interface between the brain and the periphery, we investigated whether this vascular phenotype is intrinsically compromised in the most common genetic risk factor for schizophrenia, the 22q11.2 deletion syndrome (22qDS). Blood−brain barrier like endothelium differentiated from human 22qDS+schizophrenia-induced pluripotent …
