Introduction: Post-stroke depression (PSD), characterized by low mood and low interest, is the most common complication after stroke. The limitations of PSD drug therapy often require multidisciplinary combination therapy in clinical practice. Tuina therapy and repetitive transcranial magnetic stimulation (rTMS) have shown potential in modulating neural plasticity and improving depressive symptoms.

Introduction: Despite the booming targeted protein degradation technologies, degrading cell membrane proteins remains an enormous challenge. In particular, only a limited approach is appropriate for the degradation of the G protein-coupled receptor (GPCR) superfamily. It is encouraging that accelerating GPCRs' endocytosis and switching their post-endocytic fate from recycling to lysosomal degradation would represent a promising strategy for developing chemical degraders of GPCRs.

Self-sorting exerts a pivotal role in biological self-assembly processes, enabling the hierarchical organization of biomacromolecules with exquisite selectivity. Inspired by nature, we present a programmable supramolecular coordination system where two types of ligands undergo sequential narcissistic and social self-sorting events to assemble either homoleptic or heteroleptic metal-organic cages. Homoleptic cage formation proceeds through the narcissistic self-sorting of either rigid or flexible ligands, depending on their varying sizes, whereas heteroleptic cages emerge through social self-sorting, where flexible ligands undergo adaptive conformational adjustments to achieve geometric complementarity with rigid counterparts.

Ischemic stroke, which is characterized by hypoxia and ischemia, triggers a cascade of injury responses, including neurotoxicity, inflammation, oxidative stress, disruption of the blood-brain barrier, and neuronal death. In this context, tryptophan metabolites and enzymes, which are synthesized through the kynurenine and 5-hydroxytryptamine pathways, play dual roles. The delicate balance between neurotoxic and neuroprotective substances is a crucial factor influencing the progression of ischemic stroke.
