Inflammation, Immunity, and Cardiovascular Diseases
Cardiovascular stress signals (e.g., hemodynamic shear, oxidized lipids, and ischemia) act on endothelial and immune cells to activate and amplify inflammation through NF‐κB, the NLRP3 inflammasome, and JAK/STAT signaling, inducing proinflammatory cytokines/chemokines (IL‐6, IL‐1β, TNF‐α, and CCL2) and self‐amplifying circuits; clinically, inflammatory

Aberrant SUMOylation Restricts the Targetable Cancer Immunopeptidome
Pharmacological SUMOylation inhibition (SUMOi) counteracts tumor immune evasion by unmasking an immunogenic HLA‐I peptide and neoepitope repertoire. By restoring HLA‐I ligand availability through increased antigen processing and presentation, enhanced proteasomal cleavage, and modulated TAP1 peptide affinity, SUMOi boosts tumor immunogenicity ...

PSMB8 (LMP7) but not PSMB9 (LMP2) gene polymorphisms are associated to pigeon breeder's hypersensitivity pneumonitis [PDF]
Hypersensitivity Pneumonitis (HP) is a lung inflammatory disorder caused by inhalation of organic particles by a susceptible host. However, only a small proportion of individuals exposed to HP-associated antigens develop the disease, suggesting that additional host/environmental factors may play a role.

Hypoxia and hypoxia-inducible factor (HIF) downregulate antigen-presenting MHC class I molecules limiting tumor cell recognition by T cells. [PDF]
Human cancers are known to downregulate Major Histocompatibility Complex (MHC) class I expression thereby escaping recognition and rejection by anti-tumor T cells.

Subversion of immunoproteasome subunit expression in dengue virus serotype 2-infected HepG2 cells
: INTRODUCTION: Infection with all serotypes of dengue virus (DV) results in augmented antigen presentation by MHC class I molecules. However, the upregulation of immunoproteasome subunits only results from infection with two serotypes. This study aims

Immunoproteasome deficiency protects in the retina after optic nerve crush. [PDF]
The immunoproteasome is upregulated by disease, oxidative stress, and inflammatory cytokines, suggesting an expanded role for the immunoproteasome in stress signaling that goes beyond its canonical role in generating peptides for antigen presentation ...

Human Leukocyte Antigen (HLA) and Tumor Immunity: A Critical Link in Cancer Immunotherapy
ABSTRACT Background Malignant tumors pose a serious threat to human health and survival, with profound economic consequences worldwide. Human leukocyte antigens (HLAs), encoded by the human major histocompatibility complex, represent one of the most polymorphic genetic systems and play a vital role in immune regulation.

Suppression of the macrophage proteasome by ethanol impairs MHC class I antigen processing and presentation. [PDF]
Alcohol binge-drinking (acute ethanol consumption) is immunosuppressive and alters both the innate and adaptive arms of the immune system. Antigen presentation by macrophages (and other antigen presenting cells) represents an important function of the ...

Hiding in Plain Sight: A Case of Intestinal Tuberculosis Masquerading as Benign Lower GI Bleeding
Background Intestinal tuberculosis (TB) represents the most common form of abdominal TB, often affecting the ileocaecal region. Lower gastrointestinal bleeding is an uncommon presentation and may create significant diagnostic uncertainty, particularly in immunocompromised patients and in settings where inflammatory bowel disease is also encountered ...

Colorectal cancer (CRC) remains a leading cause of cancer‐related mortality worldwide. Approximately 15% of localized and 5% of metastatic cases exhibit mismatch repair deficiency (dMMR) or high microsatellite instability (MSI‐H). While immune checkpoint inhibitors (ICIs) have revolutionized the first‐line treatment for this subgroup, 15%–46% of ...
