Polymeric biomaterial-inspired cell surface modulation for the development of novel anticancer therapeutics

Abstract

AbstractImmune cell-based therapies are a rapidly emerging class of new medicines that directly treat and prevent targeted cancer. However multiple biological barriers impede the activity of live immune cells, and therefore necessitate the use of surface-modified immune cells for cancer prevention. Synthetic and/or natural biomaterials represent the leading approach for immune cell surface modulation. Different types of biomaterials can be applied to cell surface membranes through hydrophobic insertion, layer-by-layer attachment, and covalent conjugations to acquire surface modification in mammalian cells. These biomaterials generate reciprocity to enable cell–cell interactions. In this review, we highlight the different biomaterials (lipidic and polymeric)-based advanced applications for cell–surface modulation, a few cell recognition moieties, and how their interplay in cell–cell interaction. We discuss the cancer-killing efficacy of NK cells, followed by their surface engineering for cancer treatment. Ultimately, this review connects biomaterials and biologically active NK cells that play key roles in cancer immunotherapy applications. Graphical Abstract
