Sarbecoviruses Suppress Innate Immunity by Recruiting PPM1A to Modulate STAT2 and ORF9b Phosphorylation

Advanced Science, EarlyView.
Sarbecovirus ORF9b recruits host phosphatase PPM1A to suppress innate immunity through dual mechanisms. PPM1A directly dephosphorylates ORF9b to sustain its activity and indirectly downregulates STAT2 phosphorylation to impair interferon signaling. Pharmacological inhibition of PPM1A restores antiviral responses and limits sarbecovirus replication ...

CD112 Lactylation Drives Dual Immune Evasion From CD8+ T Cells and NK Cells

Advanced Science, EarlyView.
AARS2 functions as an intracellular lactate sensor and lactyltransferase, catalyzing CD112 K412 lactylation to block ubiquitination‐dependent degradation and stabilize CD112. This pathway suppresses CD8+ T‐cell and NK‐cell cytotoxicity, enabling dual immune evasion.

A Postbiotic‐Inducing Ganoderma applanatum Polysaccharide Repairs the Intestinal Barrier via a Phocaeicola vulgatus ‐ Tridecylic Acid Axis

Advanced Science, EarlyView.
This study identifies GAP2, a bioactive polysaccharide fraction derived from Ganoderma applanatum, as a postbiotic inducer that repairs intestinal barrier damage in a gut microbiota‐dependent manner. GAP2 enriches Phocaeicola vulgatus, which degrades GAP2 and promotes tridecylic acid production, triggering Rho/CDC42 signaling and tight‐junction ...

Aged ZnO Nanoparticles Promote Breast Cancer Lung Metastasis by Remodeling the Pulmonary Microenvironment Through the CXCL10/Wnt/β‐Catenin Axis

Advanced Science, EarlyView.
In summary, pulmonary exposure to ZnO NPs, particularly aged NPs, promotes breast cancer metastasis by remodelling the lung tumour microenvironment. Aged ZnO NPs enrich M2‐macrophages, MDSCs and activated CAFs to form an immunosuppressive metastatic niche. CXCL10 from these cells drives metastasis via Wnt/β‐catenin activation.

STAT1 is a sex‐specific tumor suppressor in colitis‐associated colorectal cancer

Molecular Oncology, 2018
The interferon‐inducible transcription factor STAT1 is a tumor suppressor in various malignancies. We investigated sex‐specific STAT1 functions in colitis and colitis‐associated colorectal cancer (CRC) using mice with specific STAT1 deletion in ...

In vitro culture with IL-7 increases IFN-α-induced STAT1 activation (p-STAT1).

, 2014
PBMCs from healthy donors (n = 12) were cultured 3 days in media alone (black symbols), rhIL-7 (10 ng/ml; blue symbols) or rhIFN-α (100 U/ml; red symbols). After 3 days of culture, the cells were harvested, washed and rested overnight.

Selenomethionine Regulates the Arachidonic Acid Metabolism‐Ferroptosis‐Inflammation Axis to Ameliorate Colitis

Animal Research and One Health, EarlyView.
Selenomethionine can ameliorate arachidonic acid‐induced colonic injury through synergistic mechanisms, including alleviating inflammatory responses, improving barrier integrity, enhancing antioxidant capacity by upregulating selenoprotein expression, selectively regulating AA metabolism to reduce pro‐inflammatory oxylipins and promote the production ...

A20 Inhibits IFN‐γ Signaling in Hepatocellular Carcinoma Cells by Binding to STAT1, Compromising Anti‐Tumor Immunity [PDF]

Cancer Sci
A20 suppresses IFN‐γ signaling in HCC cells by binding to STAT1 through its ZnF7 domain, thereby reducing CXCL9, CXCL10, and HLA‐ABC expression, ultimately impairing CD8+ T‐cell‐mediated anti‐tumor immunity. ABSTRACT Immune checkpoint blockade (ICB) has demonstrated efficacy in clinical cancer therapy; however, a significant proportion of cancer ...
