Targeting DNGR‐1 with Fangchinoline Elevates Dendritic Cell Antigen Cross‐Presentation‐Mediated Antitumor Immunity in Melanoma

open access: yesAdvanced Science, EarlyView.
Fangchinoline is identified as a small‐molecule DNGR‐1 modulator that enhances dendritic‐cell cross‐presentation of tumor antigens. By engaging DNGR‐1 and activating Syk–Nox2 signaling, it promotes phagosomal ROS, antigen escape, MHC‐I presentation, and CD8+ T‐cell priming, thereby strengthening antitumor immunity and sensitizing tumors to PD‐1 ...

Post‐Translational Isoaspartate Promotes Amyloid Formation in β2‐Microglobulin

open access: yesAngewandte Chemie, EarlyView.
Chemical synthesis of five β2‐microglobulin (β2m) variants reveals the structural impact of Asn deamidation. By introducing Asp or isoAsp at susceptible Asn‐Gly sequences, we demonstrate that isoAsp17 formation specifically accelerates amyloid fibril formation, highlighting its potential contribution to dialysis‐related amyloidosis.

Transmembrane Helices Are an Overlooked Source of Major Histocompatibility Complex Class I Epitopes

open access: yesFrontiers in Immunology, 2017
About a fourth of the human proteome is anchored by transmembrane helices (TMHs) to lipid membranes. TMHs require multiple hydrophobic residues for spanning membranes, and this shows a striking resemblance with the requirements for peptide binding to ...

p300 Degradation by the p53‐SIAH1 Axis Relieves TBK1 Acetylation to Enhance Innate Antiviral Immunity

open access: yesAdvanced Science, EarlyView.
This study identifies p300 as the acetyltransferase that acetylates TBK1 and inhibits its phosphorylation. Activation of the p53‐SIAH1 axis by immune response downregulates p300 expression to sustain innate antiviral immunity. Conditional p300 knockout in alveolar epithelial cells in vivo promotes antiviral responses and suppresses virus replication ...

Non-canonical Functions of Macroautophagy Proteins During Endocytosis by Myeloid Antigen Presenting Cells

open access: yesFrontiers in Immunology, 2018
Endocytosis by myeloid antigen presenting cells such as dendritic cells and macrophages regulates both antigen processing and major histocompatibility complex (MHC) molecule trafficking during antigen presentation.

HLA‐DR+ Schwann Cells Generate the Protumor Cancer‐Neuron‐Immune Niche in Head and Neck Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
Hijacked and educated by HNSCC cells, HLA‐DR+ Schwann cells lost their normal neural‐related functions but acquired immunoregulatory phenotypes to promote CD4+ T cells transform into Tregs. HLA‐DR+ Schwann cells induced a macrophage subpopulation, Il1β.

Human Urine Stem Cells Alleviate Pulmonary Fibrosis via Inhibiting Macrophage‐Myofibroblast Transition

open access: yesAdvanced Science, EarlyView.
Therapeutic role and mechanism of human urine stem cells (hUSCs) in pulmonary fibrosis. hUSCs alleviated pulmonary fibrosis by selectively inhibiting macrophage‐myofibroblast transition (MMT) in two ways: on one hand, hUSCs inhibited mitochondrial reactive oxygen species (mtROS) production and apoptosis/senescence of epithelial cells in pulmonary ...

In silico and in vivo analysis of Toxoplasma gondii epitopes by correlating survival data with peptide–MHC-I binding affinities

open access: yesInternational Journal of Infectious Diseases, 2016
Background: Protein antigens comprising peptide motifs with high binding affinity to major histocompatibility complex class I (MHC-I) molecules are expected to induce a stronger cytotoxic T-lymphocyte response and thus provide better protection against ...

The transmembrane domain of the adenovirus E3/19K protein acts as an ER retention signal and contributes to intracellular sequestration of MHC class I molecules [PDF]

open access: yes, 2013
The human adenovirus E3/19K-protein is a type-I transmembrane glycoprotein of the endoplasmic reticulum (ER) that abrogates cell-surface transport of MHC class-I (MHC-I) and MICA/B-molecules.
