Tumor Microenvironments in Malignant Ovarian Germ Cell Tumors: MHC Class I Loss and T‐Cell Exhaustion in Dysgerminoma

Cancer Science, EarlyView.
Malignant ovarian germ cell tumor subtypes exhibit distinct tumor microenvironments. Dysgerminomas harbor abundant nonexhausted T cells, with progenitor exhausted T cells present in 60% of PD‐1–positive cases. However, MHC class I expression is lost across all analyzed subtypes, suggesting that restoring class I expression in dysgerminomas may enhance ...

Oesophageal Epithelial Cell‐Intrinsic MHCII Regulates Food Antigen‐Dependent Eosinophilic Esophagitis in an IFNγ‐Dependent Manner

Clinical &Experimental Allergy, EarlyView.
We found that oesophageal epithelial cells upregulate MHCII expression during active EoE in humans and a mouse model. MHCII expression by EECs was governed by IFNγ‐inducible transcriptional elements. EEC‐intrinsic MHCII promoted regulatory T cell accumulation and attenuated eosinophilic oesophageal inflammation.

Beyond PD‐1: Mechanisms of Resistance to Checkpoint Blockade in Classical Hodgkin Lymphoma and Next‐Generation Immune Strategies

European Journal of Haematology, EarlyView.
ABSTRACT PD‐1 inhibitors have reshaped the treatment landscape of classical Hodgkin lymphoma, yet a substantial proportion of patients exhibit primary or acquired resistance driven by tumor‐intrinsic alterations, immunosuppressive microenvironmental signals, metabolic constraints, and EBV‐mediated modulation.

Artificial lipidation of proteins and peptides: from mechanism to clinical applications

The FEBS Journal, EarlyView.
Artificial lipidation transforms protein and peptide therapeutics by attaching fatty acid chains through reversible or permanent chemical strategies. This biomimetic approach delivers four key therapeutic advantages: extended circulation times (enabling weekly instead of daily dosing), alternative administration routes including oral delivery, precise ...

Tissue Resident Memory Cells: Friend or Foe?

Immunology, EarlyView.
Tissue‐resident memory T cells (TRM cells) are specialised immune cells in barrier tissues like the lungs, skin and gut, providing rapid host defence and tumour surveillance. Their retention and differentiation are regulated by molecules such as CD69, CD103 and TGF‐β. Dysregulation of TRM cells can lead to chronic activation, driving conditions such as
