Context-dependent role of complement in cancer could provide novel prognostic biomarkers to inform treatment decisions

Research led by investigators at Ghent University in Belgium showed dysregulation of the complement part of the immune system, regulated by the pro-inflammatory protein interleukin (IL)-6, is a key driver of severe COVID-19 and a good target for drugs to treat the effects of the disease.

The immune system is essential to protect organisms from internal and external threats. The rapidly acting, non-specific innate immune system includes complement, which initiates an inflammatory cascade and can form pores in the membranes of target cells to induce cell lysis. Regulation of protein homeostasis (proteostasis) is essential for normal cellular and organismal function, and has been implicated in processes controlling immunity and infection. Chaperones are key players in maintaining proteostasis in both the intra- and extracellular environments. Whilst intracellular proteostasis is ...
