Both PDCD2 and PDCD2-like proteins have PDCD2_C terminal domains, but their functions are stilt unclear. After analysis of their expression in Gene Expression Omnibus, we hypothesized that they played a rote in inflammation. In Daudi cells exposed to Lipopolysaccharides, PDCD2-like RNA was upregulated, whereas PDCD2 was downregulated. Overexpression of PDCD2-like gene effectively attenuated tumor necrosis factor (TNF)-alpha release but elevated interteukin (IL)-6 and PDCD2 expression induced by lipopolysaccharide (LPS). It is possible that both proteins have anti-inflammatory effects Like IL-6. The results have implications for understanding the function of PDCD2/PDCD2-like proteins and may help in the development of novel anti-inflammatory drugs.
