Direct visualization of peptide/MHC complexes at the surface and in the intracellular compartments of cells infected in vivo by Leishmania major.

open access: yesPLoS Pathogens, 2010
Protozoa and bacteria infect various types of phagocytic cells including macrophages, monocytes, dendritic cells and eosinophils. However, it is not clear which of these cells process and present microbial antigens in vivo and in which cellular ...

CD1-mediated immune responses in mucosal tissues: molecular mechanisms underlying lipid antigen presentation system

open access: yesExperimental and Molecular Medicine, 2023
The cluster of differentiation 1 (CD1) molecule differs from major histocompatibility complex class I and II because it presents glycolipid/lipid antigens. Moreover, the CD1-restricted T cells that recognize these self and foreign antigens participate in

Interferon‐Driven Biomarkers and Synergistic Therapy for PRMT5 Inhibition in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
Triple‐negative breast cancer exhibits variable sensitivity to PRMT5 inhibition. Basal interferon signaling is identified as a key biomarker of response. PARP inhibition with olaparib induces IFN signaling, sensitizing resistant TNBC cells to PRMT5 inhibitors.

A step-by-step overview of the dynamic process of epitope selection by major histocompatibility complex class II for presentation to helper T cells [version 1; referees: 4 approved]

open access: yesF1000Research, 2016
T cell antigen receptors (TCRs) expressed on cytotoxic or helper T cells can only see their specific target antigen as short sequences of peptides bound to the groove of proteins of major histocompatibility complex (MHC) class I, and class II ...

METTL10‐Mediated PIAS3 Methylation Links Purine Metabolism to Gastric Cancer Progression

open access: yesAdvanced Science, EarlyView.
METTL10‐mediated methylation of PIAS3 at K442 inhibits its SUMO E3 ligase activity toward MITF. This reduces MITF SUMOylation and subsequent RNF4‐mediated ubiquitination, leading to MITF protein accumulation and gastric cancer progression. Abstract Metabolic dysregulation plays a significant role in the development of gastric cancer (GC).

Single‐Cell Transcriptome Atlas Reveals the Underlying Mechanism of Kynurenic Acid in the Regulation of Tumor Immune Microenvironment in Glioblastoma

open access: yesAdvanced Science, EarlyView.
KYNA regulates the tumor immune microenvironment in glioblastoma. KYNA reprograms the balance between T cell exhaustion and activation to suppress glioblastoma progression through inhibiting exhaustion‐associated markers (such as PD‐1, LAG3, and TOX) and enhancing immune activation and cytotoxicity markers including granzymes GZMA and GZMB.

Three‐Year Follow‐Up of Neoadjuvant Tislelizumab with Chemotherapy in Locally Advanced Gastric and Gastroesophageal Junction Adenocarcinoma: Revealing Cancer‐Associated Fibroblast Heterogeneity Corresponding to PD‐1 Blockade Efficacy

open access: yesAdvanced Science, EarlyView.
Heterogeneous cancer‐associated fibroblasts orchestrate dual immune microenvironments in LAGC. Abstract The potential for immunotherapy in patients with locally advanced gastric cancer (LAGC) is recently confirmed. To report the 3‐year follow‐up data are aimed from a novel clinical trial. This is a prospective single‐arm phase II trial.

Structural analysis of the adenovirus type 2 E3/19K protein using mutagenesis and a panel of conformation-sensitive monoclonal antibodies [PDF]

open access: yes, 2008
The E3/19K protein of human adenovirus type 2 (Ad2) was the first viral protein shown to interfere with antigen presentation. This 25 kDa transmembrane glycoprotein binds to major histocompatibility complex (MHC) class I molecules in the endoplasmic ...

Class I histocompatibility antigens and insulin receptors: evidence for interactions. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1986
We provide evidence for an interaction between mouse class I major histocompatibility complex antigens and insulin receptors. Antibodies against class I but not class II major histocompatibility complex antigens immunoprecipitate photoaffinity-labeled hepatic insulin receptors.

Single‐Cell RNA Sequencing of Thyroid Tissues Reveals Pathogenesis of Graves' Disease

open access: yesAdvanced Science, EarlyView.
Using single‐cell RNA sequencing and TCR profiling, this study constructed an immune cell atlas in thyroid tissue of Graves’ disease (GD), revealing dominant IFN‐γ‐secreting CD4+ T cells, expanded Tph and CD11c+ B cells, and enriched T/NK cells. Notably, GD thyroid follicular cells (TFCs) activated γδ T cells, which recruited cDC1 cells, suggesting a ...
