Ligand-targeted toxins (LTTs) are bioengineered molecules which are composed of a targeting component linked to a toxin that induces cell death once the LTT binds its target. Bispecific targeting allows for the simultaneous targeting of two receptors. In this review. we mostly focus on the epidermal growth factor receptor (EGFR) as a target. https://www.roneverhart.com/Phi-Mu-Mom-Dad-Embroidered-Button/
