Stem cells in the bone marrow provide a life-long supply of blood and immune cells. If they display defects – either caused by hereditary diseases or blood cancer – the transplantation of bone marrow cells of a suitable donor is often the only therapeutic option. To avoid rejection of the transplanted stem cells, the patients immune response needs to be dampened. The consequence: Bacteria and viruses have an easy time. Especially infections with the highly prevalent Cytomegalovirus are a leading cause of clinical complications – ranging from graft rejection to life-threatening disease. Scientists of TWINCORE and the German Cancer Research Center have now switched prespective: They investigated the influence of virus infections of bone marrow donors on the success of a transplantation. Their – striking – results were recently published in „Cell Reports“.

Scientists studying infections used to focus mainly on the direct interaction of the immune system with pathogens, but have since moved on to look more closely at the interactions that go on between microbiota, immune system and pathogen. Using mouse models, researchers from the Helmholtz Centre for Infection Research (HZI) recently elucidated a relationship between gut microbiomes of various compositions and the susceptibility to Salmonella infections. In their study, the scientists from Braunschweig identified several bacterial families that have a protective effect against Salmonella. The researchers also elucidated the immune mechanism in the mucosa of the gut that is regulated by the protective bacterial families. Published in Cell Host & Microbe, the results of the study of the HZI scientists are an important step towards a better understanding of the interactions of the triad of microbiota, immune system and pathogen.

Intestinal bacteria are suspected of causing cardiovascular disease, since they produce trimethylamine as a metabolic product that is hazardous to humans. They utilise food ingredients that are present mainly in meat and eggs. The causal relationships are still vague at this time, since important insights into these microbial communities are still lacking. A research team from the Helmholtz Centre for Infection Research (HZI) recently developed a special function-based diagnostic method that allows the measurement of the trimethylamine production potential of intestinal communities and identification of the specific bacterial species involved in this process. Based on these insights, the microbiome may become a target of therapeutics in the distant future. The researchers published the results in Microbiome.

In recent years, more and more pathogens have become resistant to previously time-proven antibiotics. This scenario gives scientists all over the world cause to find new anti-infective substances and to develop them for application in medicine. A true opportunity for the discovery of new antibiotics is the investigation of previously unknown bacteria and fungi from habitats that have not yet been examined thoroughly, as these microorganisms produce a wealth of chemical substances with antibiotic activity. Scientists from the Helmholtz Centre for Infection Research (HZI) have isolated a large number of new bacterial strains, some of which show an activity against resistant pathogens and have already been promoted to the early preclinical development phase.

More and more pathogens are developing resistances to antibiotics. There is therefore an urgent need for new anti-infectives. In this regard, Eva Medina of the Helmholtz Centre for Infection Research is looking for therapeutic alternatives that will circumvent the renewed formation of antibiotic resistance.

Cells inside the human body contain a flexible polymer network called the cytoskeleton which consists of actin filaments - and other components - and undergoes constant assembly and disassembly. This turnover of actin filaments allows cells to change shape and move. Such movements are important for example during embryonic development, wound healing but also for a properly operating immune system. To be able to move through tissue, cells need to expend energy and apply force. For example, immune cells advance into all regions of our body to detect and fight pathogens. In turn, though, some pathogens can abuse the cytoskeleton to adhere to or penetrate into cells.
