CCL3 is not involved in the recruitment of NK cells during RSV infection.

Chemotaxis of enriched NK cells to recombinant CCL3 or supernatant (supe) from RSV, UV-RSV, or control exposed macrophages; anti-CCL3, anti-TNF or control antibody was used to assess the chemotactic effect of specific mediators (A). BALB/c mice were treated on day −1 and +1 of RSV infection with anti-CCL3 (white bars) or control Ig (black bars). Lung cell number (B), percentage lung NK cells (C) and lung viral load (D) on day 4 post infection. Bars represent n≥3 ± SEM, ** p<0.01.
