Targeted Degradation of ZBP1 with Covalent PROTACs for Anti-Inflammatory Treatment of Infections.

Z-DNA binding protein 1 (ZBP1) has emerged as a critical pathogen-sensing protein that upon activation, triggers necroptotic signaling cascades, leading to a potent inflammatory response and potentially causing significant tissue damage. However, available drugs specifically developed for the effective inhibition or degradation of ZBP1 is still lacking so far. In this study, we developed a potent covalent recognition-based PROTAC (C-PROTAC) molecule for the degradation of ZBP1.

Here, we report a robust method that utilizes quantum-dot-based single-virus tracking and machine learning to generate unique single-virus infection fingerprint data from viral trajectories and detect the dynamic changes in viral movement following drug administration.

Quantitatively Dissecting Triple Roles of Dynactin in Dynein-Driven Transport of Influenza Virus by Quantum Dot-Based Single-Virus Tracking.

After entering host cells by endocytosis, influenza A virus (IAV) is transported along microfilaments and then transported by dynein along microtubules (MTs) to the perinuclear region for genome release. Understanding the mechanisms of dynein-driven transport is significant for a comprehensive understanding of IAV infection. In this work, the roles of dynactin in dynein-driven transport of IAV were quantitatively dissected using quantum dot-based single-virus tracking.

Revealing Different Pathways for Influenza A Virus To Reach Microtubules after Endocytosis by Quantum Dot-Based Single-Virus Tracking.

Actin- and microtubule (MT)-based transport systems are essential for intracellular transport. During influenza A virus (IAV) infection, MTs provide long tracks for virus trafficking toward the nucleus. However, the role of the actin cytoskeleton in IAV entry and especially the transit process is still ambiguous.

Atomically dispersed ternary FeCoNb active sites anchored on N-doped honeycomb-like mesoporous carbon for highly catalytic degradation of 4-nitrophenol.

In the last decades, 4-nitrophenol is regarded as one of highly toxic organic pollutants in industrial wastewater, which attracts great concern to earth sustainability. Herein, atomically dispersed ternary FeCoNb active sites were incorporated into nitrogen-doped honeycomb-like mesoporous carbon (termed FeCoNb/NHC) by a two-step pyrolysis strategy, whose morphology, structure and size were characterized by a set of techniques. Further, the catalytic activity and reusability of the as-prepared FeCoNb/NHC were rigorously examined by using 4-NP catalytic hydrogenation as a proof-of-concept model.
