Abstract: This document provides methods and materials involved in binding a binder (e.g., an antibody, antigen binding fragment, antibody domain, CAR, cell engager, and/or ADC) to a CD94/NKG2A polypeptide. For example, binders (e.g., antibodies, antigen binding fragments, antibody domains, CARs, cell engagers, and/or ADCs) that bind to a CD94/NKG2A polypeptide and methods and materials for using one or more such binding molecules to treat a mammal (e.g., a human) having cancer and/or a viral infection are provided.

Abstract: A tumor tissue-penetrating peptide specifically binding to neuropilin, or a fusion protein, a small molecule drug, a nanoparticle, or a liposome having the peptide fused therein is provided, as well as a method for preparing the same and a pharmaceutical composition comprising the same for treating, diagnosing, or preventing cancer or angiogenesis-related diseases. The tumor tissue-penetrating peptide is fused to the C-terminus of an anticancer antibody heavy-chain constant region (Fc) and the fused antibody specifically binds to neuropilin, and specifically accumulates in tumor tissue, widens intercellular gaps between tumor vascular endothelial cells, promotes extravasation, increases infiltration within tumor tissue, and shows a remarkably increased in vivo tumor-suppressing activity.
