Cytolysis activity
WebSep 10, 2024 · Cytolytic activity, as a new biomarker for immunotherapy, can characterize the anti-tumor immunoactivity of immune cells, such as CD8+cells, cytotoxic T cells, and macrophages [8]. Therefore, it is necessary to explore genes and predictive models related to the CYT level to provide a basis for the prognosis management of lung cancer. WebGroup B streptococci (GBS) express a beta-haemolysin/cytolysin that contributes to disease pathogenesis. We report an independent discovery and extension of a genetic locus encoding the GBS beta-haem
