Table 2 shows gene expression positive correlations detected between M1 macrophage phenotype or inflammatory markers (i.e., TNF-α, CD16, IL-1β), M2 macrophage phenotype or anti-inflammatory markers (i.e., IL-10, CD206, CEBPB) and fibrotic markers (i.e., TGFB1, ACTA2) with A2AR, in renal tissue samples of DD. The gene discussed is TNF; the disease is dentin dysplasia.
