Engineering the cell surface has emerged as a significant method for manipulating cell behavior and determining cell fate. Regulating the composition or structure of cell membranes has the potential to impact the essential roles they play in biointerfacing, signal transduction, and compartmentalization. This presents significant prospects for the advancement of cell-based biomedicine. DNA nanotechnology has emerged as a promising experimental toolbox for cell membrane engineering, owing to its high programmability and excellent biocompatibility. Nongenetic strategies based on DNA nanotechnology for programming cell membranes have seen rapid growth over the past decade, showing promising prospects for cell-based therapeutic diagnostics. In this review, the nongenetic-based strategies for the functionalization of cell membranes are first introduced. The biological applications of DNA nanotechnology in cell membrane engineering are also highlighted and summarized, including molecular sensing, modulation of cell membrane signaling pathways and intercellular interactions, and establishment of transmembrane channels. Finally, the challenges and prospects of DNA nanotechnology in cell membrane engineering are discussed.

The cell surface display system employs carrier proteins to present target proteins on the outer membrane of cells. This system enables functional proteins to be exposed on the exterior of living cells without cell lysis, allowing direct interaction with the surrounding environment. A major limitation of conventional approaches is the difficulty in displaying large-sized enzymes or antibodies, despite their critical roles in applications requiring functional domains that must remain intact, such as catalytic or antigen-binding sites.

In recent years, there has been a rapid increase in the incidence of thyroid carcinoma (TC). Our study focuses on the regulatory effect of circular RNAs on metabolism of TC, aiming to provide new insights into the mechanisms of progression and a potential therapeutic target for TC. In this study, we identified high expression levels of circPSD3 in TC tissues through RNA sequencing.

Type 2 diabetes (T2D) is characterized by persistent and unresolved tissue inflammation caused by the infiltration and dysregulation of immune cells. Current therapeutics targeting inflammatory immune cells for T2D remain limited. In this study, we analyzed single cell RNA from metabolic organs in T2D, revealing increased macrophage accumulation and a pathogenic macrophage subpopulation defined as NOD-like receptor (NLR) family pyrin domain-containing 3 (NLRP3) inflammatory and metabolically activated macrophages.

The immune system uses a variety of DNA sensors, including endo-lysosomal Toll-like receptors 9 (TLR9) and cytosolic DNA sensor cyclic GMP-AMP (cGAMP) synthase (cGAS). These sensors activate immune responses by inducing the production of a variety of cytokines, including type I interferons (IFN). Activation of cGAS requires DNA-cGAS interaction.
