IgG‐Bridging–Seeded Synergistic Aggregation of SARS‐CoV‐2 Spikes Underlies Potent Neutralization by a Low‐Affinity Antibody

Advanced Science, EarlyView.
Low‐affinity antibodies are frequently disregarded in discovery pipelines. This work reports P5‐1C8, a Class 1 SARS‐CoV‐2 antibody with weak trimer binding (KD‐to‐IC50 > 3700‐fold) yet potent neutralization of Omicron JN.1. Structural, biophysical, functional, and coarse‐grained simulations collectively demonstrate that transient inter‐spike IgG ...

Depletion of the RNA‐Editing Enzyme ADAR1 Invigorates the Antitumor Immunity of NK Cells

Advanced Science, EarlyView.
ADAR1 is upregulated in NK cells from melanoma patients, impairing their function. Its loss enhances NK cell tumor infiltration and cytotoxicity in vitro and in vivo. Mechanistically, ADAR1 deficiency destabilizes CD38 mRNA to reduce its expression, thereby increasing NK cell mobility and killing, which nominates it as a therapeutic target for NK cell ...

Blocking variant surface glycoprotein synthesis alters ERES/ Golgi homeostasis in Trypanosoma brucei

, 2018
The predominant secretory cargo of bloodstream form Trypanosoma brucei is Variant Surface Glycoprotein (VSG), comprising ~10% total protein and forming a dense protective layer. Blocking VSG translation using Morpholino oligonucleotides triggered a precise pre/cytokinesis arrest.

Endothelial Cell‐Based Vascular Bandages for Blood–Brain Barrier Repair and Targeted siRNA Delivery

Advanced Science, EarlyView.
mECs restore blood–brain barrier function after cerebral ischemia–reperfusion by simultaneously targeting, supporting, and regulating the damaged vasculature. mECs home to injured cerebral vessels through interactions with highly expressed VLA‐4, reinforce endothelial integrity by forming new junctions, and, upon OGD‐SN treatment, acquire enhanced ...

MARPLE: A Proximity‐Triggered CRISPR‐Cas13 Platform for Ultrasensitive Antibody Detection

Advanced Science, EarlyView.
MARPLE is a modular CRISPR‐Cas13 immunoassay that uses antibody‐induced proximity to trigger a toehold‐exchange reaction, releasing an RNA activator for Cas13. This one‐pot, isothermal architecture enables ultrasensitive (femtomolar) and highly specific detection of diverse antibodies, including therapeutic, pathogen‐specific, and cancer‐associated ...

Biomimetic Organic Nanozyme as Tumor Vaccines for Targeted Suppression of Ammonia‐Induced T Lymphocyte Death to Augment Breast Cancer Immunotherapy

Advanced Science, EarlyView.
The organic nanozyme IR‐IHpd, which has NIR‐PDT and POD‐like activity, is designed for continuous ROS generation. It is co‐encapsulated with CB‐839 and coated with DC membranes to simultaneously target tumors and T cells. Under NIR irradiation, immunogenic cell death is activated. Concurrently, CB‐839 suppresses ammonia‐induced T lymphocyte death (AITD)

Cytokine‐Engineered Chimeric Antigen Receptor‐T Cell Therapy: How to Balance the Efficacy and Toxicity

Advanced Science, EarlyView.
Cytokine‐engineered CAR‐T cells represent a promising immunotherapy against malignancies due to direct tumor killing and potent immunity response. However, significant toxicities, including CRS and ICANS, have restricted clinical applications. How to keep the risk‐benefit balance of the advanced therapy is of great importance for maximizing the benefit

Microenvironment‐Guided Evolution of ssDNA‐SWCNT Probes for Selective Recognition of Aggressive Prostate Cancer Phenotypes

Advanced Science, EarlyView.
Random ssDNA–SWCNT(single strand DNA‐single walled carbon nanotube) library is functionally screened and evolved using high‐throughput 3D prostate tumor spheroids via iterative positive and negative selection, enabling the identification of NIR‐II fluorescent ssDNA‐SWCNT nanoprobe specific for prostate cancer.
