Infectious diseases

Epidemiologist Tobias Pischon not only studies the incidence of chronic diseases in populations, but also why they develop. To better predict and prevent these conditions, he searches for molecular markers in the blood and studies the influence of environment, genes, and lifestyle.

Can an aging immune system be coaxed into responding to vaccination like its’ younger self? In “Nature Aging,” Sebastian Hofer, Katja Simon and colleagues discuss emerging interventions that may boost older adults’ response to vaccines. They are also recruiting volunteers for a clinical trial of their own.

A team led by Simon Haas has developed a technology to decode how immune cells talk to each other – revealing how our bodies respond to infections, how miscommunication can trigger autoimmune diseases, and why some people don’t respond to immunotherapies. The study was published in “Nature Methods.”

A new computer program allows scientists to design synthetic DNA segments that indicate, in real time, the state of cells. Reported by the Gargiulo lab in “Nature Communications”, it will be used to screen for anti-cancer or viral infections drugs, or to improve gene and cell-based immunotherapies.

The details of many immune defense mechanisms are still unknown, but a new study sheds light on one such mechanism. Writing in “The EMBO Journal”, researchers led by Oliver Daumke and Misha Kudryashev of the Max Delbrück Center describe exactly how GBP1 proteins render bacteria harmless by encapsulating them.

Many people with post-COVID syndrome who suffer from fatigue six months after a coronavirus infection are still severely physically impaired up to 20 months afterward. The study by ECRC researcher Judith Bellmann-Strobl and her colleagues was published in “eClinicalMedicine.”

The herpes simplex virus-1 can sometimes cause a dangerous brain infection. Combining an anti-inflammatory and an antiviral could help in these cases, report scientists with the Rajewsky and Landthaler labs and the Organoid Platform at the Max Delbrück Center in “Nature Microbiology.”

A new tool can identify cells that are actively responding to a SARS-CoV-2 infection. As reported in "Science Advances" by the Gargiulo lab, it can be used to screen for effective COVID-19 therapies and can be tailored to study other viruses as well.

The signaling molecules of the immune system should trigger a response only where necessary. To prevent a life-threatening spread to the rest of the body, connective tissue can absorb these molecules like a sponge. A team led by Thomas Blankenstein presents this mechanism in “Nature Immunology.

Algorithms developed at the Max Delbrück Center are able to quickly detect new SARS-CoV-2 variants in wastewater. But that’s not all: the tool, which Altuna Akalin and his colleagues have now presented in “Science of the Total Environment”, can also find other pathogens.
