Figure 1From: Placental malaria is associated with attenuated CD4 T-cell responses to tuberculin PPD 12 months after BCG vaccination Gating of CD4 T-cells expressing IFNγ, IL-2 and CD154. Following selection of lymphocytes by forward and side scatter characteristics and CD4 T-cells by gating on high expression of CD4, quadrant gates were set on a/the negative control sample and then applied to b/the PPD-stimulated sample. Sample selected as representative as it has the median CD154 response among PM- infants at 12 months.Back to article page
