Multifaceted Catalytic Glucose Depletion and Reactive Oxygen Species-Scavenging Nanoenzyme Composite Hydrogel for Facilitating Diabetic Bone Regeneration.

Regeneration of diabetic bone defects remains a formidable challenge due to the chronic hyperglycemic state, which triggers the accumulation of advanced glycation end products (AGEs) and reactive oxygen species (ROS). To address this issue, we have engineered a bimetallic metal-organic framework-derived Mn@CoO@Pt nanoenzyme loaded with alendronate and Mg ions (termed MCPtA) to regulate the hyperglycemic microenvironment and recover the osteogenesis/osteoclast homeostasis. Notably, the Mn atom substitution in the CoO nanocrystalline structure could modulate the electronic structure and significantly improve the SOD/CAT catalytic activity for ROS scavenging.

Simultaneous Blockade of CD209 and CD209L by Monoclonal Antibody Does Not Provide Sufficient Protection Against Multiple Viral Infections In Vivo.

Many virus species, including Ebola virus, Marburg virus, SARS-CoV-2, dengue virus (DENV) and Zika virus (ZIKV), exploit CD209 and CD209L as alternative or attachment receptors for viral cis- or trans-infection. Thus, CD209 and CD209L may be critical targets for the development of therapeutic monoclonal blocking antibody drugs to disrupt the infection process caused by multiple viruses. Here, we produced a human chimeric monoclonal blocking antibody that simultaneously blocks CD209 and CD209L, namely 7-H7-B1.
