免疫学专业英语

Patient outcomes are influenced by many confounding factors peri-operatively, including the type of surgery, anaesthesia, transfusion, and immune competence. We have previously demonstrated ( in-vitro ) that compared to allogeneic blood transfusion (ABT), intraoperative cell salvage (ICS) improves immune competence. The peri-operative immune response is complex. Altered or impaired immune responses may predispose patients to develop adverse outcomes (i.e., post-operative wound infection, pneumonia, urinary tract infection etc.) Surgical patients may develop infection, even without the confirmed presence of a definite microbiological pathogen. With all these factors in mind it is important to consider changes in immune cell numbers (and sub-populations) and functional capacity during peri-operative transfusion.

One of the greatest challenges to cancer therapy is tumor cell plasticity. Cancer cells can rapidly alter their phenotype to promote survival and evade immune cell attack, while the plasticity of other cells in the tumor microenvironment (such as immune cells, which need to be able to respond to a diverse range of bodily threats) can be leveraged to further promote tumor growth and progression. This Essay discusses the mutual plasticity of cancer and immune cells, with a focus on epithelial–mesenchymal plasticity in tumor cells, and explores how this interplay contributes to tumor progression and can be targeted therapeutically.
