Cancer-Associated Fibroblast-Secreted Exosomes Regulate Macrophage Polarization in Pancreatic Cancer via the NOD1 Pathway.

Metastasis is a major cause of poor prognosis of pancreatic cancer. Exosomes (Exos) regulate cancer progression by modulating macrophage polarization. This study aimed to investigate the effects of cancer-associated fibroblast (CAF)-released Exos on macrophage polarization in pancreatic cancer and the molecular mechanisms.

The expression of MALAT1, plasma brain natriuretic peptide, and Tei index in sepsis-induced myocardial injury.

Purpose: We sought to investigate the expression of MALAT1, plasma brain natriuretic peptide, and Tei index in sepsis-induced myocardial injury.

Methods: The current retrospective analysis focused on 146 sepsis patients admitted to our hospital from February 2021 to March 2023. Based on the presence or absence of myocardial injury, the patients were divided into two groups: the sepsis group (n = 80) and the sepsis-induced myocardial injury group (n = 66).

Roles of SIRT3 in cardiovascular and neurodegenerative diseases.

Sirtuin-3 (SIRT3) in mitochondria has nicotinamide adenine dinucleotide (NAD+)-dependent protein deacetylase activity. As such, SIRT3 is crucial in cardiovascular and neurodegenerative diseases. Advanced proteomics and transcriptomics studies have revealed that SIRT3 expression becomes altered when the heart or brain is affected by external stimuli or disease, such as diabetic cardiomyopathy, atherosclerosis, myocardial infarction, Alzheimer's disease, Huntington's disease, and Parkinson's disease.

Adoptive T cell therapy targeting an inducible and broadly shared product of aberrant mRNA translation.

Prolonged exposure to interferon-gamma (IFNγ) and the associated increased expression of the enzyme indoleamine 2,3-dioxygenase 1 (IDO1) create an intracellular shortage of tryptophan in the cancer cells, which stimulates ribosomal frameshifting and tryptophan to phenylalanine (W>F) codon reassignments during protein synthesis. Here, we investigated whether such neoepitopes can be useful targets of adoptive T cell therapy. Immunopeptidomic analyses uncovered hundreds of W>F neoepitopes mainly presented by the HLA-A24:02 allele.

A small-molecule enhancer of STAT1 affects herpes simplex keratitis prognosis by mediating plasmacytoid dendritic cells migration through CXCR3/CXCL10.

Herpes simplex keratitis (HSK) is a prevalent infectious corneal disorder. This study aims to explore the role of plasmacytoid dendritic cells (pDCs) in HSK, an area that remains underexplored. The investigation centers on the effects of a STAT1 transcription enhancer, 2-NP, on pDCs and its underlying mechanisms.
