Designer DNA Architecture‐templated Drug Conjugates (DDA‐DCs) are comprised of a DNA nanomaterial decorated with multiple drug‐loaded DNA aptamers. DDA‐DCs use a combination of multiple aptamer types, each recognizing a different membrane protein to achieve precise targeting of cancer cells.

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels
A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

New Twist on Neuronal Insulin Receptor Signaling in Health, Disease, and Therapeutics
Long after the pioneering studies documenting the existence of insulin (year 1967) and insulin receptor (year 1978) in brain, the last decade has witnessed extraordinary progress in the understanding of brain region-specific multiple roles of insulin ...

Insulin and insulin receptor abnormality.
インスリンあるいはインスリン受容体の異常が糖尿病者で見い出された.インスリン受容体に結合しえない異常インスリンやプロインスリンが産生されるインスリン遺伝子の異常,細胞表面のインスリン受容体の数や機能が減少するインスリン受容体遺伝子の異常あるいはインスリン受容体に対する自己抗体の存在が報告されている.いずれも高インスリン血症の存在が診断への手掛りとなるが,インスリンの異常ではインスリン抵抗性は存在しないがインスリン受容体の異常では存在する点が最大の鑑別点となる.インスリン遺伝子あるいはインスリン受容体遺伝子の異常が見い出された家系について検討すると,糖尿病の発症年齢,重症度は均一でなく,その発症には他の遺伝子異常あるいは環境要因の関与も推定され,糖尿病の発症にはいくつかの因子が関与していると考えられた.

Structure and dynamics of dynorphin peptide and its receptor [PDF]
Dynorphin is a neuropeptide involved in pain, addiction and mood regulation. It exerts its activity by binding to the kappa opioid receptor (KOP) which belongs to the large family of G-protein coupled receptors. The dynorphin peptide was discovered in 1975, while its receptor was cloned in 1993.

Engineering Assembloids to Mimic Graft‐Host Skeletal Muscle Interaction
This study develops a graft‐host skeletal muscle assembloid model combining neuromuscular organoids with tissue‐engineered constructs. Pre‐seeding decellularized muscles with myogenic cells enhances cell migration and axon invasion from the organoid. The model exhibits regenerative capacity following acute damage, advancing the understanding of human ...
