Abstract/OtherAbstract:
|
The choroid plexus (CP) is increasingly recognized as an important contributor to central nervous system (CNS) inflammation by recruitment of inflammatory cells and release of inflammatory cytokines. Here we investigate the role of the CP epithelium (CPE) as a source of three pro-inflammatory molecules of potential importance in inflammation after acute spinal cord injury (SCI): IL-1β, TNF-α, and hsp70. Immunohistochemical (IHC) staining for these three proteins was performed on 4th ventricular CPE from 4 dogs euthanized 12-48h after spontaneous acute SCI, and from 4 neurologically normal dogs euthanized for other reasons. IHC staining was quantified using Aperio ImageScope software. IHC staining in the CPE of dogs with acute SCI was 2.2, 1.6 and 1.5 times higher than that of normal dogs, for IL-1β, TNF-α, and hsp70, respectively. Increases were statistically significant (p<0.1) for IL-1β and TNF-α, and closely approached significance for hsp70. These findings indicate that the CPE could serve as an important source of these inflammatory mediators after SCI. There was also an inverse correlation between IL-1β and hsp70 staining and duration of clinical signs in acute SCI, suggesting that increased expression of these proteins by the CPE may be of particular importance in the immediate-early inflammatory response after acute SCI. |
