Nanobody‐Decorated Lipid Nanoparticles for Enhanced mRNA Delivery to Tumors In Vivo

Advanced Healthcare Materials, EarlyView.
This study presents a targeted mRNA‐LNP platform engineered with anti‐PSMA nanobodies for prostate cancer therapy. Using different in vivo models, the authors demonstrate selective uptake and mRNA delivery in PSMA+ cancer cells. However, while targeting is enhanced, mRNA delivery efficacy is limited by tissue penetration, tumor necrosis, and immune ...

Mechanobiologically Engineered Mimicry of Extracellular Vesicles for Improved Systemic Biodistribution and Anti‐Inflammatory Treatment Efficacy in Rheumatoid Arthritis

Advanced Healthcare Materials, EarlyView.
Triblock copolymer‐reinforced liposomal mimics of extracellular vesicles are engineered with tunable membrane elasticity. A semi‐elastic formulation (Tri‐ARTEX8:2) co‐encapsulating stem cell cytosolic extract and AntagomiR155 targets inflamed joints via the ELVIS effect, reprograms macrophages from M1 to M2, and markedly alleviates collagen‐induced ...

Rolling Ultrasharp Microneedle Spheres Enable Topical Delivery of Biologics Through the Skin

Advanced Healthcare Materials, EarlyView.
Rolling ultraminiaturized microneedle spheres (RUMS), created via two‐photon polymerization, unlock effective and painless topical delivery of messenger RNA (mRNA) and drugs through the skin. By gently forming thousands of microscopic pores, RUMS boost skin permeability by up to 100‐fold.

Nanocarrier‐Based Targeting of Pattern Recognition Receptors as an Innovative Strategy for Enhancing Sepsis Therapy

Advanced Healthcare Materials, EarlyView.
This review highlights recent progress in nanocarriers targeting pattern recognition receptors (PRRs), including Toll‐like and NOD‐like receptors, for enhancing the treatment of bacterial sepsis and related complications. These nanomedicines deliver antibiotics and anti‐inflammatory agents while modulating immune responses.

The elemental mechanism of transcriptional pausing. [PDF]

, 2019
Transcriptional pausing underlies regulation of cellular RNA biogenesis. A consensus pause sequence that acts on RNA polymerases (RNAPs) from bacteria to mammals halts RNAP in an elemental paused state from which longer-lived pauses can arise.
