During systemic immune challenge, the organum vasculosum laminae terminalis (OVLT) with its dense vascularization by fenestrated capillaries lacking blood-brain barrier function allows direct access of circulating pyrogens to brain tissue located in close vicinity to the preoptic area. We aimed to analyze direct responses of OVLT cells to exposure to(More)
Primary microcultures of the organum vasculosum laminae terminalis (OVLT) and the area postrema (AP), brain sites with an incomplete blood-brain barrier, were established from topographically excised rat pup tissue, with cellular identification by marker protein-specific immunocytochemistry. Employing the ratio calcium imaging technique, we showed for the(More)
The area postrema (AP) represents the sensory circumventricular organ lacking endothelial blood-brain barrier function in direct vicinity to the 4th cerebral ventricle. Administration of lipopolysaccharide (LPS), as opposed to muramyldipeptide (MDP) or fibroblast-stimulating lipopeptide-1 (FSL-1), caused fast transient rises in intracellular calcium(More)
The area postrema (AP) represents the medullary sensory circumventricular organ lacking endothelial blood-brain barrier function at the base of the 4th cerebral ventricle. Administration of tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta) or the nitric oxide (NO) donor diethylamino-diazenolate-2-oxide (DEA) caused fast transient rises(More)
