TLR2 and gastric cancer: In our research, we have demonstrated an increased expression of receptors found on T lymphocytes CD4+TLR2+, CD8+TLR2+, B lymphocytes CD19+TLR2+, myeloid dendritic cells BDCA1+CD19-TLR2+, plasmacytoid dendritic cells BDCA2+CD123+TLR2+, classical monocytes CD14+CD16-TLR2+, and non-classical monocytes CD14+CD16+TLR2+; moreover, this expression increased with the stage of gastric cancer on the TNM scale.
