Monitoring the Dynamics of Alzheimer's Disease Biomarkers and the APOE–Tau Axis via Human Cerebral Organoids with Immuno‐SERS

open access: yesAdvanced Science, EarlyView.
Noninvasive and sensitive detection of tau protein dynamics across developmental stages and APOE genotypes remain a challenge in Alzheimer's disease (AD) research. This study reveals the dynamics of tau secretion in label‐free manner using surface‐enhanced Raman spectroscopy (SERS) and human cerebral organoids (hCOs). This study provides novel insights

Biohybrid Computing with Proteinoids and Algae

open access: yesAdvanced Science, EarlyView.
We developed a novel biohybrid computing system by combining proteinoid microspheres with algae. The biological mixture creates spontaneous electrical oscillations. These oscillations can perform simple logic operations, such as AND, OR, NAND, and NOR gates. Environmental factors like temperature and pH affect how the system works.

Direct Sequencing of 5‐Methylcytosine and 5‐Hydroxymethylcytosine at Single‐Base Resolution Unravels Their Distinct Roles in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
This study introduces two orthogonal sequencing methods, CMD1‐Deaminase sequencing (CD‐seq) and CMD1‐TET bisulfite sequencing (CT‐seq), that enable direct, independent detection of 5mC. Using these approaches together with ACE‐seq or TAB‐seq for 5hmC identification, the study reveals a significant reduction in 5hmC, but not 5mC, in the hippocampus of ...

Nature‐Inspired Nanostructures from Multiple‐Species Biomembranes: Rational Engineering and Therapeutic Applications in Tumor‐Targeted Nanomedicine

open access: yesAdvanced Science, EarlyView.
Naturally derived biomembrane nanostructures by mimicking evolutionarily optimized biological architectures could effectively suppress tumor growth and have emerged as a compelling strategy in translational biomedicine. This review provides a systematic overview of rational design and underlying antitumor therapeutic mechanisms of mammalian cells ...
