Losartan Enhances Radiosensitivity by Reversing Immunosuppressive Tumor Microenvironment Induced by Radiotherapy in TNBC

open access: yesCancer Science, EarlyView.
Our study demonstrates that the angiotensin receptor blocker losartan enhances the efficacy of radiotherapy in triple‐negative breast cancer by reversing the immunosuppressive tumor microenvironment. Losartan reprograms tumor‐associated macrophages, inhibits myeloid‐derived suppressor cell function, and boosts CD8+ T‐cell activity.

Hepatocyte TrkB Acts as a Gatekeeper Against MASH‐Related Liver Fibrosis by Suppressing the TGFβ/CCL2 Axis and Macrophage Infiltration

open access: yesCell Proliferation, EarlyView.
Hepatocyte TrkB is identified as a critical gatekeeper against MASH‐related fibrosis. Mechanistically, TrkB inhibits the TGFβ/SMAD3/FOS axis to suppress CCL2 secretion, thereby blocking pathogenic macrophage recruitment and ameliorating liver fibrosis.

STAT1 Gain-of-Function Mutations Cause High Total STAT1 Levels With Normal Dephosphorylation

open access: yes
Signal transducer and activator of transcription (STAT1)1 gain of function (GOF) pathogenic variants have been associated with increased levels of phosphorylated STAT1 and STAT1-dependent cellular responses. Delayed dephosphorylation was proposed as the underlying mechanism leading to the characteristically raised pSTAT1 levels.

Ligand‐specific tuning of CLEC10A signalling strength and dendritic cell responses through engagement of different GalNAc‐containing glycan structures

open access: yesThe FEBS Journal, EarlyView.
The authors investigated the effects of various glycan ligands for CLEC10A, a lectin receptor expressed on dendritic cells (DCs). Monocyte‐derived DCs were stimulated with glycan‐conjugated dendrimers in combination with the TLR1/2 ligand Pam3CysK4, and responses were investigated at the mRNA and protein level.

Innate Immune Activation Is a Strong Suppressor of CCL22 and Impedes Regulatory T Cell–Dendritic Cell Interaction

open access: yesImmunology, EarlyView.
During homeostasis, CCL22 is secreted by dendritic cells (DC), which mediate contacts between regulatory T cells (Treg) and DC to maintain immune balance. Activation of innate immunity via microbes or pattern recognition receptor (PRR) agonists induces the secretion of several soluble factors (e.g., type I and II interferons, IL‐10), which mediate ...
