Provided herein are methods, compounds, and compositions useful for targeted delivery of compounds to non-native cells ectopically expressing cell surface receptors. Such methods, compounds, and compositions are useful, for example, in gene therapy mediated ectopic expression of cell surface receptors and targeted delivery of compounds, such as conjugated oligonucleotides, to the non-native cells ectopically expressing cell surface receptors. Such methods, compounds, and compositions can be useful, for example, to treat, prevent, delay or ameliorate disease in an individual by targeted reduction of a gene of interest in the non-native cell ectopically expressing cell surface receptors.
