On the basis of morphological and immunological study of biopsies of the colon in patients with diverticulosis was revealed that microscopic inflammation of the mouth of the diverticulum is characterized by several features that include excessive proliferation of the epithelium, the predominance of macrophage reaction in the development of the immune response, increased cell adhesion and unusual ratio between the expression of cytokines and other regulatory molecules. Changes in the structure of the formed diverticula tissue are associated with dysregulation of many processes of tissue metabolism and morphogenesis. These include the dysregulation of cell renewal of the epithelium (increased level of proliferation of epithelial cells and inhibition of apoptosis), degradation of extracellular matrix components, moderate vascular reaction. All these processes take place on the background a particular form of immune protection and adaptation mechanisms.

Background: In patients with sepsis, platelets are activated and adhere to neutrophils, forming platelet-leukocyte aggregates (PLAs) that lead to the development of MODS. ARDS is one of the main manifestations of septic MODS. We designed this study to explore the effects of different anti-plate therapy drugs on platelet activation and platelet-leukocyte aggregate (PLA) formation in the early stage of septic ARDS.

Background: Mitochondrial dysfunction and damage can result in the release of mitochondrial DNA (mtDNA) into the cytoplasm, which subsequently activates the cGAS-STING pathway, promoting the onset of inflammatory diseases. Various factors, such as oxidative stress, viral infection, and drug toxicity, have been identified as inducers of mitochondrial damage. This study aims to investigate the role of mtDNA as a critical inflammatory mediator in the pathogenesis of ketamine (KET)-induced cystitis (KC) through the cGAS-STING pathway.

Background: Traditional Chinese medicine (TCM) is a valuable resource for drug discovery and has demonstrated excellent efficacy in treating inflammatory diseases. This study aimed to develop a universal gene signature-based strategy for high-throughput discovery of anti-inflammatory drugs, especially Traditional Chinese medicine (TCM).
Methods: The disease gene signature of liposaccharide-stimulated THP-1 cells and drug gene signatures of 655 drug candidates were established via sequencing.

Acute rejection (AR) is a significant complication in liver transplantation, impacting graft function and patient survival. Kupffer cells (KCs), liver-specific macrophages, can polarize into pro-inflammatory M1 or anti-inflammatory M2 phenotypes, both of which critically influence AR outcomes. Angiopoietin-like 4 (ANGPTL4), a secretory protein, is recognized for its function in regulating inflammation and macrophage polarization.

Aim: To explore the potential roles of mitochondrial dysfunction in the initiation of inflammation in periodontal macrophages and to determine the mechanism underlying the involvement of dynamin-related protein 1 (Drp1) in macrophage inflammatory responses through its interaction with hexokinase 1 (HK1).
Materials And Methods: Gingival tissues were collected from patients diagnosed with periodontitis or from healthy volunteers. Drp1 tetramer formation and phosphorylation were analysed using western blot.
