In uninfected neutrophils, the median frequency of CD66b+/CD83+ transdifferentiated P3 population was 1.36% (1.00%–1.49%) (Fig. 4A), which, following infection, translated into a substantial increase in CD66b+/CD83+ to 51.05% (49.48%–53.94%), P < 0.05 (Fig. 4B and C). This evidence concerns the gene CEACAM8 and infection.
