LAMP1 and pertussis: By contrast, a statistically significant increase in CD107a expression on NK cells was seen in response to all three vaccine components (pertussis: median 2·2%, range 0·2–22·2; DT: median 0·5%, range 0·0–2·6; TT: median 0·5%, range 0·0–4·3) (Fig. 1d) and this was not significantly enhanced by LCC (pertussis: median 4·5%, range 0·9–20·0; DT: median 0·9%, range 0·0–3·0; TT: median 0·6%, range 0·1–2·5) (Fig. 1e).
