Scientists in Tokyo, Japan have made a significant discovery in the field of tumor necrosis factors. Their study, published in International Archives of Allergy and Immunology, reveals a complex mechanism by which CCL5 (RANTES) contributes to prolonged eosinophilic inflammation and asthma exacerbation after a viral infection. The researchers found that

Researchers at the University of Texas M.D. Anderson Cancer Center have identified the key mechanism through which glioma cells migrate, with the insulin-like growth factor binding protein 2 (IGFBP2) and integrin alpha5 interaction playing a crucial role. This interaction, which enhances cell migration, was found to be mediated by

Researchers from Johns Hopkins University have discovered that protein C inhibitor (PCI) regulates cathepsin L activity and cell-mediated tumor cell migration. According to the study, PCI inhibits cathepsin L with an inhibition rate of 3.0x10^5 M^-1 s^-1, suggesting a crucial role in hemostasis, cardiovascular, and metastatic
