Fig. 1.

A representative dot plot of TLR4 expression on CD3⁺ T lymphocytes (a), CD3⁺ CD4⁺ T lymphocytes (b), CD3⁺ CD8⁺ T lymphocytes (c), CD19⁺ B lymphocytes (d), granulocytes (e) and CD14⁺ monocytes (f). Gates were set around lymphocytes (a–d), granulocytes (e) or monocytes (f) according to the forward- and side-scatter values on a flow cytometer. The horizontal and vertical lines were set with an irrelevant isotype-matched fluorescent conjugate. The percentage of positive cells is indicated. Results obtained from a RSV infected infant are shown.
