Florida-James, G. D., McFarlin, B. K., O’Connor, D. P., Simpson, R. J., Booth, S., Florida-James, G., …Simpson, R. J. (2010)
The impact of acute strenuous exercise on TLR2, TLR4 and HLA.DR expression on human blood monocytes induced by autologous serum. European Journal of Applied Physiology, 110(6), 1259-1268. https://doi.org/10.1007/s00421-010-1616-2
Acute exercise alters the surface expression of toll-like receptors (TLRs) and HLA.DR on blood monocytes, which could transiently compromise immunity. As serum factors might b...

The influence of age and cardiorespiratory fitness on circulating angiogenic T cells and CXCR4 expression.

Conference Proceeding
Ross, M. D., Malone, E. M., Simpson, R. J., & Florida-James, G. (2015)
The influence of age and cardiorespiratory fitness on circulating angiogenic T cells and CXCR4 expression
Aging is associated with endothelial dysfunction, reduced angiogenic capabilities, and an increase in arterial stiffness. Additionally, regular exercise is known to offset the...

Total lymphocyte CD8 expression is not a reliable marker of cytotoxic T-cell populations in human peripheral blood following an acute bout of high-intensity exercise

Journal Article
Campbell, J. P., Guy, K., Cosgrove, C., Florida-James, G., & Simpson, R. J. (2008)
Total lymphocyte CD8 expression is not a reliable marker of cytotoxic T-cell populations in human peripheral blood following an acute bout of high-intensity exercise. Brain, Behavior, and Immunity, 22(3), 375-380. https://doi.org/10.1016/j.bbi.2007.09.001
Cytotoxic T-lymphocytes co-express the T-cell receptor, CD3 and the MHC I restricted antigen CD8. Although total CD8 expression is often used to identify CD8+ T-cells in blood...
