Smart Delivery Systems Responsive to Cathepsin B Activity for Cancer Treatment

Pharmaceutics, 2023
Cathepsin B is a lysosomal cysteine protease, contributing to vital cellular homeostatic processes including protein turnover, macroautophagy of damaged organelles, antigen presentation, and in the extracellular space, it takes part in tissue remodeling,

Trifunctional Sialylation‐Based SF‐ZIF@NA Hydrogel for Selective Osteoclast Inhibition and Enhanced Bone‐Vessel Regeneration in Osteoporotic Bone Defects

Advanced Science, EarlyView.
This study introduces the SF‐ZIF@NA hydrogel system for osteoporotic bone defect treatment. The hydrogel inhibits osteoclast fusion by removing sialic acid and preserves the anabolic function of precursor osteoclasts (pOCs). It also releases Zn2⁺ in acidic conditions, promoting osteogenesis and angiogenesis.

CD4-independent human immunodeficiency virus infection involves participation of endocytosis and cathepsin B. [PDF]

PLoS ONE, 2011
During a comparison of the infectivity of mNDK, a CD4-independent human immunodeficiency virus type 1 (HIV-1) strain, to various cell lines, we found that HeLa cells were much less susceptible than 293T and TE671 cells.

Nitroxoline impairs tumor progression in vitro and in vivo by regulating cathepsin B activity

OncoTarget, 2015
Cathepsin B is a ubiquitously expressed lysosomal cysteine protease that participates in protein turnover within lysosomes. However, its protein and activity levels have been shown to be increased in cancer. Cathepsin B endopeptidase activity is involved

IRF8 Drives Conventional Type 1 Dendritic Cell Differentiation and CD8+ T Cell Activation to Aggravate Abdominal Aortic Aneurysm Development

Advanced Science, EarlyView.
This study highlights the critical role of IRF8 in the development of AAA. IRF8 activation promotes the differentiation of cDC1s, which in turn recruit and activate CD8+ T cells, contributing to aortic wall degradation. The study identifies the IRF8‐cDC1‐CD8+ T cell axis as a key pathway in AAA progression, offering new potential therapeutic targets to

Dual‐Locking the SARS‐CoV‐2 Spike Trimer: An Amphipathic Molecular “Bolt” Stabilizes Conserved Druggable Interfaces for Coronavirus Inhibition

Advanced Science, EarlyView.
A new amphipathic molecule, S416 is discovered, that locks the SARS‐CoV‐2 spike protein in its closed state, blocking viral entry. S416 acts as a molecular bolt, binding six sites: three between adjacent RBDs and three connecting NTDs to RBDs. This dual‐locking mechanism stiffens the spike structure and reduces its flexibility.

Biomimetic Microstructured Scaffold with Release of Re‐Modified Teriparatide for Osteoporotic Tendon‐to‐Bone Regeneration via Balancing Bone Homeostasis

Advanced Science, EarlyView.
This study develops RPTH by re‐modifying teriparatide and designs a biomimetic microstructured scaffold (BMRP) loaded with RPTH to address osteoporotic tendon‐to‐bone interface repair. The BMRP restores tissue architecture by balancing bone homeostasis and remodeling the microstructure, achieving functional recovery in an osteoporotic rotator cuff tear

Precision‐Guided Stealth Missiles in Biomedicine: Biological Carrier‐Mediated Nanomedicine Hitchhiking Strategy

Advanced Science, EarlyView.
Diagram illustrating the binding methods of NPs and biological barriers. The biological carrier‐mediated nanomedicine hitchhiking strategy (BCM‐NHS) utilizes two distinct techniques: the surface‐based “Backpack” method, which relies on ligand‐receptor binding, covalent conjugation, and non‐covalent binding, and the encapsulated “Trojan horse” approach,
