Blood Immunoproteasome Activity Is Regulated by Sex, Age and in Chronic Inflammatory Diseases: A First Population-Based Study

Cells, 2021
Dysfunction of the immunoproteasome has been implicated in cardiovascular and pulmonary diseases. Its potential as a biomarker for predicting disease stages, however, has not been investigated so far and population-based analyses on the impact of sex and

PDGF-D-induced immunoproteasome activation and cell-cell interactions

Computational and Structural Biotechnology Journal, 2023
Platelet-derived growth factor-D (PDGF-D) is abundantly expressed in ocular diseases. Yet, it remains unknown whether and how PDGF-D affects ocular cells or cell-cell interactions in the eye.

A Tripartite Model for EBV‐Driven Multiple Sclerosis: B Cell Survival, Altered Self‐Presentation, and HLA‐DR15‐Restricted T Cell Cross‐Reactivity

iNew Medicine, EarlyView.
ABSTRACT This commentary integrates findings from three recent Cell reports to establish a unified mechanistic model of multiple sclerosis (MS) driven by the interplay between Epstein‐Barr virus (EBV) and the HLA‐DR15 genotype. EBV promotes CNS autoimmunity through three distinct but intersecting mechanisms.

Immunoproteasome function maintains oncogenic gene expression in KMT2A-complex driven leukemia

Molecular Cancer, 2023
Pharmacologic targeting of chromatin-associated protein complexes has shown significant responses in KMT2A-rearranged (KMT2A-r) acute myeloid leukemia (AML) but resistance frequently develops to single agents.

Cardiovascular toxicity from immune checkpoint inhibitor therapy: an inflammatory continuum

British Journal of Pharmacology, EarlyView.
Immune checkpoint inhibitor (ICI) therapy has markedly improved outcomes in advanced malignancies but has also revealed a distinct spectrum of cardiovascular immune‐related adverse events. Myocarditis represents the most severe manifestation, while non‐inflammatory left ventricular dysfunction and vascular inflammation have emerged as additional ...

Biogenesis of TNF‐α‐insights into proteostasis and inflammation

The FEBS Journal, EarlyView.
TNF‐α biogenesis, trafficking, and signalling are tightly and reciprocally coupled to cellular proteostasis systems, including ER chaperones and endoplasmic reticulum‐associated degradation. This bidirectional crosstalk determines whether TNF‐α responses are adaptive or proteotoxic.

Immunoproteasome acted as immunotherapy ‘coffee companion’ in advanced carcinoma therapy

Frontiers in Immunology
Immunoproteasome is a specialized form of proteasome which plays a crucial role in antigen processing and presentation, and enhances immune responses against malignant cells.

Brain endothelial cells exposure to malaria parasites links type I interferon signalling to antigen presentation, immunoproteasome activation, endothelium disruption, and cellular metabolism

Frontiers in Immunology, 2023
IntroductionCerebral malaria (CM) lethality is attributable to induction of brain edema induction but the cellular mechanisms involving brain microvascular endothelium in CM pathogenesis are unexplored.ResultsActivation of the STING-INFb-CXCL10 axis in ...

Stimulating proteasomal degradation in human proteinopathies

The FEBS Journal, EarlyView.
The proteasome mediates the degradation of a wide range of proteins. Boosting proteasomal degradation may be beneficial in several disease contexts and can be achieved either by modulating proteasome activity or by improving substrate delivery. Proteasome activity can be enhanced by increasing proteasome abundance, inducing constitutive gate opening ...

ONX 0914 Lacks Selectivity for the Cardiac Immunoproteasome in CoxsackievirusB3 Myocarditis of NMRI Mice and Promotes Virus-Mediated Tissue Damage

Cells, 2020
Inhibition of proteasome function by small molecules is highly efficacious in cancer treatment. Other than non-selective proteasome inhibitors, immunoproteasome-specific inhibitors allow for specific targeting of the proteasome in immune cells and the ...
