Fig. 3From: Maternal exposure to ultrafine particles enhances influenza infection during pregnancyPulmonary T cell profiles from dissociated lung tissue. A CD8 + T cell counts, showing noticeable reduction in the UFP-PR8 group compared to all other groups. B CD4 + T cell counts. C Count of CD4 + T cells belonging to the Th1 lineage (IFN- +). D Count of CD4 + T cells belonging to the Th2 lineage (IL-4 +). E Th1/Th2 cell ratio in the lung, used as an indicator of immune system bias. F Count of CD4 + T cells belonging to the Th17 lineage (IL-17 +), showing a slight reduction in the UFP-PR8 group compared to the FA-PR8 groupBack to article page
