<i>Ex vivo</i> cytokine production by splenocytes in response to stimulation with RSV.

<p>IFN-γ (Panel A) and IL-5 (Panel B) production in splenocyte cultures after stimulation with inactivated RSV was determined by cytokine ELISA. Cytokines in the culture supernatants were assayed after 3 days of culturing. Data from 6 mice per group is shown. Bars and error bars represent means ± SD. The data shown are representative of at least 3 separate experiments. Data was analyzed by a Mann-Whitney U test and a p-value of ≤ 0.05 was considered to represent a significant difference. * p≤0.05, ** p≤0.01, *** p≤0.001.
