Density plot of T-type Ca2+ currents generated in differentiated ND7/23 cells following HSV-1 infection and treatment with IL-6. A, B, C) HSV-1 infection causes a leftward shift in current densities. D) IL-6 treatment for 24 h reverses the HSV-1 evoked shift in current densities. The number of cells analyzed under each condition was: control (n=22), +IL-6 (n=15), +HSV (n=22), and HSV+Il-6 (n=25) from at least 3 different cell cultures.
