The so-called B cells are part of the immune system's memory. Their memories of previous infections or vaccinations provide the template for antibodies that have a protective effect the next time they come into contact with a pathogen. Researchers at TWINCORE, Centre for Clinical and Experimental Infection Research, have now been able to show that the combination of infection and subsequent vaccination in the case of the SARS-CoV-2 coronavirus even protects against future variants of the virus by the memory cells virtually predicting the future. The team describes how this works in the European Journal of Immunology. The TWINCORE is a joint institution of the Helmholtz Centre for Infection Research (HZI) in Braunschweig and Hannover Medical School (MHH).

Scientists at the Helmholtz Centre for Infection Research (HZI) rely on working with laboratory animals to research infectious diseases in more detail and to understand the complex interactions between pathogens and their hosts. To this end, the HZI operates a central animal facility for breeding and keeping mice and hamsters.

Leukemia is the most common cancer in children. Cancer treatment severely weakens the children's immune system and they can easily develop opportunistic infections. One of the most common causes of such complications is the cytomegalovirus (CMV) from the herpes virus family. The department “Viral Immunology” headed by Prof. Luka Cicin-Sain at the Helmholtz Centre for Infection Research (HZI) in Braunschweig is now investigating immunotherapy options against CMV. The project is enabled by a donation from the Günter Hansmeier Krebsstiftung in Braunschweig, which is funding the position of a doctoral researcher for three years.
