Research conducted over the last 15 years indicates that cAMP is generated not just from the plasma membrane but also from intracellular compartments, particularly in endosomes, where receptors are redistributed during the endocytosis process. This review centers on the parathyroid hormone type 1 receptor (PTHR) as a model for a peptide hormone GPCRs that generates cAMP from various locations with distinct duration and pharmacological effectiveness. We discuss how structural dynamics simulations aid in designing ligands that induce cAMP location bias, ultimately answering how the spatiotemporal generation of cAMP affects pharmacological responses mediated by the PTHR.

Disruptions in synaptic transmission and plasticity are early hallmarks of Alzheimer's disease (AD). Endosomal trafficking, mediated by the retromer complex, is essential for intracellular protein sorting, including the regulation of amyloid precursor protein (APP) processing. The VPS35 subunit, a key cargo-recognition component of the retromer, has been implicated in neurodegenerative diseases, with mutations such as L625P linked to early-onset AD.

Background: T follicular helper (TFH) cell lymphoma is complex, and we hope to provide a new perspective for its diagnosis.
Methods: We analysed the immunophenotypes of 89 mature T-cell lymphomas, including 52 nodal lymphomas of TFH origin, as well as 32 benign lymph node samples and 30 healthy bone marrow samples, by flow cytometry (FCM).
Results: Among pan-T cell markers, CD4CD5CD3 is the typical pattern that distinguishes TFH lymphoma from other T-cell lymphomas.

Background: Preoperative treatment with glucagon-like peptide-1 receptor agonists (GLP-1 RAs) before bariatric surgery has not been studied. Therefore, we investigated the impact of neoadjuvant treatment with GLP-1 RAs on weight loss and postoperative outcomes in patients who underwent sleeve gastrectomy for severe obesity.
Method: A retrospective single-center study was conducted between January 2022 and December 2023.

Anti-mGluR1 encephalitis is a rare autoimmune disorder manifesting with cerebellar syndrome with varying levels of severity. However, limited data exist regarding the clinical features and treatment strategies for patients suffering from encephalitis associated with anti-mGluR1 antibodies. Herein, we comprehensively review and discuss clinical features of anti-mGluR1 encephalitis to enhance our understanding of this rare disorder.

Epizootic hemorrhagic disease virus (EHDV) causes severe disease in ruminants. We assessed the pathogenicity of the Chinese EHDV-7 isolate YN09 in mice lacking the type I interferon receptor and in sheep. In mice, YN09 infection resulted in 100% mortality, with histopathological lesions, viral replication, and immunoreactivity in multiple organs.
