PD-1 Levels - Is Her One Really EJFR?

The epidermal growth factor, family of receptors are all proteins on the cell surface. They serve as signaling growth factors so that the cells have to talk to each other with signals. EGFR is certainly the poster child for lung cancer precision medicine, her one. Her two is the posterChild for breast cancer precision medicine and we hope to see many more types of tumors that can be targeted with her two target therapy. It'll be interesting to see what happens there in terms of PD-1 levels.
