PPARA and infection: We found that these differentially expressed genes were enriched in chemokines and NOD‐like receptor signaling pathways in Stmn1+ AMs, while proteasome and Peroxisome proliferator‐activated receptor (PPAR) signaling pathways were enriched in Stmn1− AMs (Figure S7B), suggesting that these two subtypes might play different roles in the progression of infection.
