Background: Glucagon-like peptide-1 (GLP-1) is a crucial incretin hormone secreted by intestinal endocrine L cells. Given its pivotal physiological role, researchers have developed GLP-1 receptor agonists (GLP-1 RAs) through structural modifications. These analogues display pharmacological effects similar to those of GLP-1 but with augmented stability and are regarded as an effective means of regulating blood glucose levels in clinical practice.

The fluorescent imaging of pathologically accumulated β-amyloid (Aβ) proteins is of significant importance to the diagnosis of Alzheimer's disease (AD). In the paper, we prepared two new NIR probes, NIR-1 and NIR-2, through hydrophilic modification of introducing water-soluble bioactive groups such as polyethylene glycol (PEG) and morpholine to tune in vivo pharmacokinetics for specific detection of soluble and insoluble Aβ species. The in vitro assessments confirm that both NIR-1 and NIR-2 display strong near-infrared (NIR) fluorescence (FL) enhancement upon association with Aβ42 monomers, oligomers or aggregates (λem > 670 nm) and show high sensitive, rapid and selective response towards Aβ42 species.

Chimeric antigen receptor (CAR) T-cell therapy has reshaped the face of cancer treatment, leading to record remission rates in previously incurable hematological cancers. These successes have spurred interest in adapting the CAR platform to a small yet pivotal subset of CD4 T cells primarily responsible for regulating and inhibiting the immune response, regulatory T cells (Tregs). The ability to redirect Tregs' immunosuppressive activity to any extracellular target has enormous implications for creating cell therapies for autoimmune disease, organ transplant rejection, and graft-versus-host disease.

Background: In the realm of plant diseases, those caused by fungi and oomycetes are particularly challenging to manage, resulting in significant economic losses. There exist diverse active substances in natural products and developing them into fungicides holds great significance. At the initial phase of our research, we discovered that Syringa pinnatifolia extract demonstrates broad-spectrum inhibitory activity against phytopathogenic fungi.

Protein -glycosylation, as one of the most crucial post-translational modifications, plays a significant role in various biological processes. The structural alterations of -glycans are closely associated with the onset and progression of numerous diseases. Therefore, the precise and specific identification of disease-related -glycans in complex biological samples is invaluable for understanding their involvement in physiological and pathological processes, as well as for discovering clinical diagnostic biomarkers.
