Fig 1. PDE4B2 is expressed in microglia and infiltrating myeloid-lineage cells in the injured cortex at 24 hrs post-TBI.

Representative scatter plots from the ipsilateral parietal cortex of (A) sham and (B) brain-injured animals. (C) Quantification of PDE4B2⁺ inflammatory cells in the cortex at 24 hrs post-surgery. Mean ± SEM, n = 8-10/group, *p<0.05, **p<0.01, ***p<0.001 vs. Sham, Student’s unpaired t-test. ND = not detectable.
