Day of Immunology – Pupils visit the DRFZ

Today, we welcomed 50 curious students from 6th and 7th grade to learn more about the immune system and conduct their own experiments. They isolated their own DNA, stained blood cells, and discovered how the body defends itself against pathogens – and why, in diseases like rheumatism, the immune system can mistakenly attack the body itself.

To start, we introduced the students to the most important “white blood cells” and their roles in the body. They learned how macrophages and killer cells fight off pathogens and why we don’t constantly get sick, even though we are surrounded by bacteria and viruses every day. Some pupils already had impressive knowledge about immune cells. Since the DRFZ is specialized in rheumatology research, we also explained what happens when the immune system becomes misdirected and starts attacking the body’s own tissues.

After the theory, it was time for hands-on science! In our labs, the students had the chance to conduct their own experiments. One highlight was isolating their own DNA from saliva – from collecting the sample to taking home a visible DNA strand in a tube. In another lab, they stained fresh blood cells and examined them under the microscope.

Not only the students but also their teachers and our staff thoroughly enjoyed this exciting day full of new experiences. A great opportunity to experience science up close!
