Multi-omics comparison of periodontitis and peri-implantitis identifies plasma cell enrichment as a shared feature and a periodontitis-associated endothelial–plasma cell APP–CD74 axis
ObjectiveTo define the shared and divergent immune architecture of periodontitis (PD) and peri-implantitis (PI) and to identify intercellular communication programs linked to plasma cell accumulation.MethodsDifferentially expressed genes (DEGs) in PD a…
