... To quantify the relative levels of protein expression, the intensity of specific protein bands was quantified using ImageJ software (National Institute of Health, Bethesda, MD) and then normalized ... luminal, but not the abluminal, endothelial surface to increase the transcellular permeability of BMECs to HIV-1. Furthermore, the results suggest that the LPS-induced increase in the paracellular ... to release IL-6 and GM-CSF into the blood; (3) IL-6 and GM-CSF act at the luminal surface of the BMECs to enhance the transcellular transport of HIV-1 across the BBB. In our previous study,...
