Functional dynamics of G protein-coupled receptors reveal new routes for drug discovery.

G protein-coupled receptors (GPCRs) are the largest human membrane protein family that transduce extracellular signals into cellular responses. They are major pharmacological targets, with approximately 26% of marketed drugs targeting GPCRs, primarily at their orthosteric binding site. Despite their prominence, predicting the pharmacological effects of novel GPCR-targeting drugs remains challenging due to the complex functional dynamics of these receptors.

Altered metabolic function induced by Aβ-oligomers and PSEN1 mutations in iPSC-derived astrocytes.

Altered energy metabolism in Alzheimer's disease (AD) is a major pathological hallmark implicated in the early stages of the disease process. Astrocytes play a central role in brain homeostasis and are implicated in multiple neurodegenerative diseases. Although numerous studies have investigated global changes in brain metabolism, redox status, gene expression and epigenetic markers in AD, the intricate interplay between different metabolic processes, particularly in astrocytes, remains poorly understood.

Reconsidering the Role of Radiotherapy for Inoperable Gastric Cancer: A Systematic Review of Gastric Radiotherapy Given With Definitive and Palliative Intent.

Aims: The role of radiotherapy (RT) for inoperable gastric cancer (IGC) is commonly low-dose, given reactively for symptoms (e.g. bleeding), in contrast to the oesophagus, where high quality evidence exists for higher doses of RT.

Preclinical Development of T Cells Engineered to Express a T-Cell Antigen Coupler Targeting Claudin 18.2-Positive Solid Tumors.

The T-cell antigen coupler (TAC) is a chimeric receptor that facilitates tumor antigen-specific activation of T cells by co-opting the endogenous T-cell receptor complex in the absence of tonic signaling. Previous data demonstrate that the TAC affords T cells with the ability to induce durable and safe antitumor responses in preclinical models of hematologic and solid tumors. In this study, we describe the preclinical pharmacology and safety of an autologous Claudin 18.
