KLRC2 and neoplasm: One identified pathway is the interaction between mHsp70 and the heterodimer of the CD94 lectin receptor and NKG2A or NKG2C on NK cells primed with the TKD 14mer peptide (TKDNNLLGRFELSG, aa 450–463), a sequence derived from the Hsp70 protein expressed on the membrane of tumor cells [32,33,34].
