Age-associated microglial transcriptome leads to diminished immunogenicity and dysregulation of MCT4 and P2RY12/P2RY13 related functions.

The aging process is marked by a time-dependent deterioration in cellular functions, particularly the immune and neural systems. Understanding the phenotype acquisition of microglia, the sentinel immune cells of the brain, is crucial for understanding the nature of age-related neurological diseases. However, the specific phenotype adopted by microglia during aging remains a subject of debate and is contingent on the chosen experimental model.

Mast cells, immune sentinels that respond to various stimuli in barrier organs, provide defense by expressing pattern recognition receptors, such as Toll-like receptors (TLRs). They may affect inflammatory responses and wound healing. Here, we investigated the effect of TLR2/6-stimulated mast cells on wound healing in keratinocytes.

Background And Aims: Previous studies have confirmed that alcohol can increase the sensitivity of the pancreas to stressors and exacerbate the severity of pancreatitis when excessive alcohol intake is combined with other causes. In the current work, this study attempted to explore how does alcohol regulate cerulein-induced acute pancreatitis, especially before inflammation occurs.
Methods: Proteomics was performed to analyze the differentially expressed proteins in pancreatic tissues from a rat model of pancreatitis.
SFAs facilitates ceramide's de novo synthesis via TLR4 and intensifies hepatocyte lipotoxicity.

Background: Non-alcoholic steatohepatitis (NASH), an advanced manifestation of non-alcoholic fatty liver disease (NAFLD), is characterized by hepatocyte injury, inflammation, and fibrosis. Saturated fatty acids (SFAs) have emerged as key contributors to hepatocyte lipotoxicity and disease progression. Toll-like receptor 4 (TLR4) acts as a sentinel for diverse ligands, including lipopolysaccharide (LPS) and endogenous molecules like palmitic acid (PA)-induced ceramide (CER) accumulation, promoting hepatocyte demise.

Bacteriophage-derived dsRNA (bp-dsRNA), also known as Larifan, is a poly-functional and wide-spectrum antiviral medication with potent interferonogenic activity. In the lungs of golden Syrian hamsters infected with SARS-CoV-2, Larifan substantially reduces viral load and decreases infection-induced pathological lesion severity. Alveolar macrophages (AM) are key sentinel cells in the lung, which play an important role in antiviral innate immune responses and, at the same time, can trigger infection-associated hyper-inflammatory response.
