N2 - The unilateral chronical constriction injury (CCI) used as a neuropathic pain model causes the elevation of proinflammatory cytokines levels not only in the dorsal root ganglia (DRG) related to damaged nerve, but also in remote DRG and central nervous system structures. We purpose that one of the possible pathways for spread of neuroinflammation could be over the blood-cerebrospinal fluid barrier present in choroid plexus (CP). We used the intravenous injection of fluorescent conjugated dextrane (FluoroEmerald - FE) to clarify our hypothesis. Twelve Wistar male rats were divided to the 3 days (n=5) and 21 days (n=5) of CCI groups, two rats were naive. The FE was intravenously applied at time of CCI survival and rats were sacrificed after 18 hours of FE circulation, perfused transcardially by Zamboni´s fixative. Distribution of FE and simultaneous immunohistochemical detection for resident (ED2) and activated (ED1) macrophages, antigen presenting cells (APC; MHC-II) and microglia (OX-42) was studied in CP using coronal cryostat sections through the brain. FluoroEmerald particles were presented in cuboidal epithelial cells of CP. The activated macrophages, microglia and APC positive for FE were found in CP stroma. Epiplexal Kolmer cells immunostained for ED2 and MHC-II were loaded by FE. In addition, FE particles were also found in ventricular ependymal cells (EC). Our results suggest that composite effect of CCI and FE causes immune reaction in CP followed by diffusion of FE particles into EC.
