METTL7A Downregulation Drives SLC1A5‐Mediated Glutamine Competition to Promote Tumor Proliferation and Suppress CD8+ T Cell Immunity in Gastric Cancer

Advanced Science, EarlyView.
GC cells enhance glutamine accumulation by upregulating SLC1A5 expression. This upregulation not only boosts GC cell proliferation, but also outcompetes CD8+ T cells for glutamine and suppresses their antitumor immunity. Mechanistically, METTL7A deficiency in GC induces SLC1A5 overexpression via an m6A‐dependent pathway and N‐glycosylation ...

Characterisation of llama antibody fragments able to act as HIV-1 entry inhibitors [PDF]

, 2009
Human immunodeficiency virus type 1 (HIV-1) entry into cells is mediated by the functional envelope spike, which consists of trimers of gp120 bound to gp41.

Stress Hyperglycemia Drives CD4+ T Cell PANoptosis and Postoperative Organ Injury via Monocyte‐Derived Succinate

Advanced Science, EarlyView.
High glucose is linked to reduced succinate dehydrogenase activity in CD14+ monocytes, accompanied by succinate accumulation and extracellular release. Extracellular succinate exacerbates mitochondrial ROS production and mtDNA release in CD4+ T cells. Cytosolic mtDNA then activates Z‐DNA binding protein 1 (ZBP1) and engages ZBP1‐associated inflammatory

TRIM28‐Derived Peptide Exerts Anti‐Tumor Roles by Stabilizing Tumor Suppressive BRD7 Protein in Multiple Cancers

Advanced Science, EarlyView.
An α‐helical peptide, TAB12, designed to mimic the TRIM28 binding interface, competitively disrupts the TRIM28‐BRD7 interaction, thereby blocking ubiquitin‐mediated degradation of the tumor suppressor BRD7. This stabilization unleashes potent anti‐tumor effects across multiple tumor types with a favorable safety profile, offering a feasible strategy ...

Canonical Antibodies Adopt Distinct Binding Modes to Recognize Viral Glycan Shields

Advanced Science, EarlyView.
Canonical Y‐shaped antibodies recognize viral glycan shields through adaptive Fab assembly states shaped by glycan organization and somatic hypermutation. Structural analyses ofbroadly neutralizing antibodies VRC35 and VRC36 across glycoproteins of HIV‐1, influenza, SARS‐CoV‐2, and Lassa viruses reveal distinct Fab assembly states, spanning monovalent,

EBV‐Driven ODC1 Upregulation Enhances Polyamine Anabolism to Promote Viral Replication and Cisplatin Resistance in Nasopharyngeal Carcinoma

Advanced Science, EarlyView.
EBV‑BZLF1 initiates ODC1‑driven polyamine anabolism that correlates with poor clinical prognosis in nasopharyngeal carcinoma. The ODC1–spermidine axis promotes viral replication, cell proliferation and innate immune evasion. Pharmacological inhibition of ODC1 rescues cisplatin sensitivity, establishing ODC1 as a viable therapeutic target for EBV ...

Nicotinamide Metabolism Constrains Memory CD8+ T Cell Formation Through a Putative HS1BP3‐SIRT1‐FOXO3‐BCL6 Axis

Advanced Science, EarlyView.
ABSTRACT Memory T cells exhibit long‐term persistence, a defining feature that underpins durable clinical responses to adoptive immunotherapies. The mechanisms that integrate metabolic cues with transcriptional control of memory fate remain undetermined. Here, we identify HS1‐binding protein 3 (HS1BP3) is preferentially expressed in memory CD8+ T cells.

Uhrf1‐Mediated PKM2 Degradation via Ubiquitination Alleviates Inflammation and Pyroptosis in Inflammatory Bowel Disease

Advanced Science, EarlyView.
Uhrf1‐mediated PKM2 ubiquitination and degradation repressed the nuclear translocation of PKM2, and EPT served as a molecular glue capable of targeting the Uhrf1–PKM2 complex to alleviate the IBD course, suggesting that the Uhrf1–PKM2 axis was a previously unrecognized strategy for treating IBD.
