Targeting phagocytosis for amyloid-β clearance: implications of morphology remodeling and microglia activation probed by bifunctional chimaeras.

Amyloid-β (Aβ), a key driver of Alzheimer's disease (AD) pathogenesis, possesses diverse harmful and clearance-resistant structures that present substantial challenges to therapeutic development. Here, we demonstrate that modulating Aβ morphology, rather than Toll-like receptor 2 (TLR2)-dependent microglia activation, is essential for effective phagocytosis of Aβ species by microglia. By developing a bifunctional mechanistic probe (P2CSKn) designed to remodel Aβ and activate TLR2, we show it restructures soluble Aβ (sAβ) and fibrillar Aβ (fAβ) into less toxic hybrid aggregates (hPAβ).

Semiconductor Superstructures with Multiple Synergistic Resonances for SERS Exploring Multiplex Noncovalent Interactions.

Noncovalent interactions (NCIs) are crucial for biological bond-forming events and have significant applications across various branches of chemistry. Here, we demonstrate for the first time the identification of multiple NCIs between two interacting species using semiconductor-based surface-enhanced Raman scattering (SERS) spectroscopy. This was accomplished by designing submicrometer-sized TiO superstructures with synergistic effects of Mie and charge-transfer resonances for SERS enhancement, enabling the TiO/4-mercaptobenzoic acid (MBA) system to achieve both high SERS activity and interfacial charge-transfer sensitivity.

Realization of 2D metals at the ångström thickness limit.

Two-dimensional (2D) metals are appealing for many emergent phenomena and have recently attracted research interests. Unlike the widely studied 2D van der Waals (vdW) layered materials, 2D metals are extremely challenging to achieve, because they are thermodynamically unstable. Here we develop a vdW squeezing method to realize diverse 2D metals (including Bi, Ga, In, Sn and Pb) at the ångström thickness limit.

Targeting USP1 Potentiates Radiation-Induced Type I IFN-Dependent Antitumor Immunity by Enhancing Oligo-Ubiquitinated SAR1A-Mediated STING Trafficking and Activation.

The magnitude of Type I interferon (IFN) mediated innate immune response within the tumor microenvironment (TME) critically influences the effectiveness of radiotherapy. Unfortunately, due to a myriad of resistance mechanisms, the double-stranded DNA (dsDNA) signals produced by tumor cells postradiotherapy often induce a diminished response from immune cells. Through chemical screening targeting deubiquitinating enzymes, we identified USP1 (Ubiquitin Specific Peptidase 1) inhibitor as an enhancer of post-radiotherapy dsDNA responses.
