Percentages of pneumococcal-stimulated positive dendritic cells (CD11c⁺) expressing HLA-DRII (a), CD86 (b) and CD80 (c) molecules are shown at baseline and in response to therapy in children with community-acquired pneumonia (CAP) treated with antibiotics plus pidotimod and in controls treated with antibiotics only. For each analysis, 30,000 events were acquired and gated on CD11c expression and side scatter properties. Mean values + SD and statistically significant differences are indicated
