Shiga toxin (Stx)-induced hemolytic uremic syndrome (HUS) poses a life-threatening complication for which a definitive treatment remains elusive. To exert its cytotoxic effect on renal cells, Stx must be delivered from the infected intestines to the kidney. However, the mechanism underlying Stx delivery remains unclear.

Fc receptor γ subunit (FcRγ) activation plays a crucial role in cancer carcinogenesis. Here, we aimed to uncover the impact of FcRγ on circulating tumor cells (CTC) colonization and the underlying mechanism. FcRγ deficient (FcRγ) mice were used to investigate the functional effects of FcRγ in cancer metastasis, and the results demonstrated that FcRγ deficiency significantly promotes metastasis.

Cetaceans have adapted to aquatic life by evolving various anatomic and physiologic traits, but biological defense mechanisms specific to aquatic mammals that protect against pathogenic microorganisms in the aquatic environment have not been elucidated. In this study, we investigated the migration of polymorphonuclear leukocytes in bottlenose dolphins in response to various chemotactic factors and compared the migration response with that of terrestrial animals such as cows and humans to characterize biological defense mechanisms unique to cetaceans. Bottlenose dolphin neutrophils showed strong chemotactic activity toward zymosan-activated serum and recombinant human interleukin-8 but no chemotaxis toward N-formyl-methionyl-leucyl-phenylalanine or leukotriene B at any concentration examined.

Numerous studies have investigated the alterations of genes, proteins, and metabolites in Behcet's disease (BD). By far, little is known about the depiction of panoramic changes underlying this disease. This study purposed to assess the consistently dysregulated genes, proteins, and metabolites in BD across publications using the vote-counting approach.

The increasing aging population and aging-associated diseases have become a global issue for decades. People over 65 show an increased prevalence and greater severity of periodontitis, which poses threats to overall health. Studies have demonstrated a significant association between aging and the dysfunction of neutrophils, critical cells in the early stages of periodontitis, and their crosstalk with macrophages and T and B lymphocytes to establish the periodontal lesion.
