Quantitative trait loci analysis reveals candidate genes implicated in regulating functional deficit and CNS vascular permeability in CD8 T cell-initiated blood-brain barrier disruption. BMC Genomics. 2013;14:678 pubmed publisher
    ..These genes encode for factors that may be potential targets for therapeutic approaches to treat disorders characterized by CD8 T cell-mediated BBB disruption. ..

    ..This study also provides insight into the effect SNVs in a single perforin allele could have on functional deficit in neurological disease. ..

    ..These findings reveal distinct functions for dendritic cells and macrophages in generating CD8+ T cell responses to neurological disease. ..

    ..A greater percentage of viable cells was also achieved through dounce homogenization. Therefore, we conclude that manual homogenization is a superior approach to isolate activated T cells from the mouse brain. ..

    ..In turn, leakage from the vasculature into the parenchyma causes brain swelling and edema. This results in a breakdown of homeostatic maintenance that likely contributes to ECM pathology. ..
  8. Willenbring R, Johnson A. Finding a Balance between Protection and Pathology: The Dual Role of Perforin in Human Disease. Int J Mol Sci. 2017;18: pubmed publisher
    ..It concludes with a novel hypothesis that diversity observed in the PRF1 gene may be an example of selective advantage that protects an individual from perforin-mediated pathology, such as BBB disruption. ..
