Tissue development deformity or tissue defect is a major clinical challenge. Tissue engineering technology provides a promising solution to these problems. Among them, functional biomaterials with regenerative abilities are one of the development trends. Polypeptide is a small molecule that can be used to modify tissue engineering materials. However, the function of a single polypeptide molecule is limited and insufficient to construct comprehensive microenvironment for tissue regeneration. Fusion peptides combining two or more polypeptide molecules with different functions were expected to achieve multiple efficacies, providing a novel solution for clinical tissue regeneration engineering applications. This paper reviews the construction methods, degradation process, and biological activities of fusion peptides, and presents recent global research progress and prospects concerning fusion peptides. It provides a reference helping to guide the future exploration and development of fusion peptide-based functional biomaterials for tissue engineering.

Anti-programmed cell death 1 (PD-1) monoclonal antibodies (mAbs) have proven to be effective in treating various cancers, including colorectal, lung, and melanoma. Despite their clinical success, some patients develop resistance to mAbs, requiring co-treatments with radio- or chemotherapy. Interleukin-15 (IL-15) is an immunostimulatory cytokine that promotes immune cell production and proliferation.

Background: Diabetic myocardial disorder (DbMD, evidenced by abnormal echocardiography or cardiac biomarkers) is a form of stage B heart failure (SBHF) at high risk for progression to overt HF. SBHF is defined by abnormal LV morphology and function and/or abnormal cardiac biomarker concentrations.
Objective: To compare the evolution of four DbMD groups based on biomarkers alone, systolic and diastolic dysfunction alone, or their combination.
Revolutionizing Heart Failure Therapy: Harnessing IVT mRNA and Fusion Protein Technology to Prolong rhBNP Half-Life.

Purpose: Recombinant human B-type natriuretic peptide (rhBNP) has been extensively proven to be an effective mean of heart failure (HF) therapy, but its clinical application is limited by its very short half-life. This study aims to combine in vitro transcribed mRNA (IVT mRNA) and fusion protein technology to develop a rhBNP-Fc mRNA drug with long half-life, high efficiency and few side effects to treat HF.
Methods: The rhBNP-Fc fusion mRNA with IgG4-Fc sequence was produced by IVT technology.

Introduction: The aim of this study is to use observational methods to evaluate reliability of evidence generated by a study of the effect of glucagon-like peptide 1 receptor agonists (GLP-1RA) on chronic lower respiratory disease (CLRD) outcomes among Type-2 diabetes mellitus (T2DM) patients.
Research Design And Methods: We independently reproduced a study comparing effects of GLP-1RA versus dipeptidyl peptidase-4 inhibitors (DPP4-i) on CLRD outcomes among patients with T2DM and prior CLRD. We reproduced inputs and outputs using the original study data (national administrative claims) and evaluated the robustness of results in comparison to alternate design/analysis decisions.
Anticancer effect of a single-chain variable fragment against pro-matrix metalloproteinase-7 in colon cancer.

Disrupting the interaction between matrix metalloproteinase-7 (MMP-7) and syndecan-2 (SDC-2) can yield anticancer effects in colon cancer cells. Here, a single-chain variable fragment (scFv) targeting the pro-domain of MMP-7 was generated as a potential candidate anticancer agent. Among the generated scFvs, those designated 1B7 and 1C3 showed the strongest abilities to inhibit the ability of MMP-7 pro-domain to directly interact with SDC-2 in vitro and decrease the cancer activities of human HT29 colon adenocarcinoma cells.
