Representative data for ChR expression by virus-specific CD8+ T cells for subject S28 and HSV-2 tetramer B7-RPR. (A) Dot plots showing expression of ChR (y axis, receptor names on top) by CD8+ bulk naive, bulk memory, or HSV tetramer-positive cells, with CLA expression on the x axis. Numbers are percentages of gated cells in each quadrant. (B) Expression levels for isotype control MAb species, fluorochrome and isotype matched to the anti-ChR MAb immediately above and naive cells. y axis thresholds are set in each case to 0.5% anti-isotype-positive events.
