The zoo in our intestine
The human intestine is home to around 100 trillion bacteria, which is about ten times the number of cells in our entire body. This internal menagerie, known as the microbiota, weighs at least one kilogram and contains over 500 different species of bacteria. What is…
Diversity is the key
During the COVID 19 pandemic, the vaccination against SARS-CoV-2 did not offer optimal protection. However, a booster vaccination against the same variant or after another infection creates what is known as "hybrid immunity", which generates a much broader protective…
New starting point discovered in the fight against Pseudomonas aeruginosa
They hope that their findings will pave the way for the development of new treatments. The study has been published in the scientific journal Proceedings of the National Academy of Sciences (PNAS). The TWINCORE is a joint institution of Hannover Medical School (MHH) and…
Thomas Pietschmann: “The pandemic shows us how effective cooperative research can be”
The Helmholtz Association conducts its research in the form of programmes that provide the framework for the activities of the individual Helmholtz Centres. The HZI is committed to the “Infection Research” programme. What are the priorities and strategic goals of the…
Luka Cicin-Sain: Getting a flu shot and the Corona booster: Does it make sense?
The Robert Koch Institute (RKI) already issued a recommendation for the Corona booster for everyone aged 18 and over. "Get both!" Prof Luka Cicin-Sain, a vaccination expert from the Helmholtz Centre for Infection Research in Braunschweig recommends. In his words, our…
Luka Cicin-Sain: “The immune response becomes inefficient with age”
Like most organs in the body, the immune system ages. How does this change the immune system's ability to fight off infections and respond to vaccinations? Our body continuously renews itself through the activity of stem cells. These provide a supply of new cells in all…
World Tuberculosis Day 2021: New drugs for old bugs
Every year, about 10 million people become infected with tuberculosis and 1.4 million die from it. This makes tuberculosis not only one of the most widespread infectious diseases, but also the deadliest. Similar to malaria or HIV, the prevalence of tuberculosis is…
From the mine to the petri dish
Alexander, you recently won the Saarland state competition Jugend forscht in the field of biology - congratulations! What was your project about? The project focuses on the search for interesting bacteria from copper mines that are capable of producing new useful…
Martin Korte: „Long COVID can become manifest even after a mild course of COVID-19“
Prof Korte, what exactly is long COVID? There is no exact definition of the term long COVID, neither in the professional literature nor in public perception. I understand it in the broadest sense to mean signs, symptoms and sequelae that persist or develop after an…
A herpes virus as a vaccination helper
Vector-based vaccines saw their public breakthrough with the development of several SARS-CoV-2 vaccines. With this technology, harmless helper viruses transport the genetic code for an antigen into host cells. The host cells produce the antigen and present it on their…
