Hannes StockingerIn contrast, the Meduni Vienna immunologist is not at all surprised: “Each person produces T cells, in a random process. If I look closely at them as an immunologist, I will identify helper cells with a receptor against the coronavirus in many people. ” Young people produce approximately one billion of these helper cells every day. When you’re old, the new formation stops, you know Stockinger. “This means that a young person is much more likely to have a protective structure in the body.”
Naive T cells and memory cells
What unfortunately was not examined in the Charité study: if these are the so-called naive T cells, they are simply there due to the random principle (also called a forward-looking immune system). Or if the cells are already with him Virus were in contact (the so-called Memory cells)
Stockinger explains: “When we come in contact with a pathogen, the system starts working and adapts to it Virus and this makes the call Memory cells. And they are responsible for ensuring that the body produces antibodies and is protected against the next virus attack. “
Too early for basic immunity
The conclusion of the Viennese immunologist, who is currently participating in this test system for Memory cells and to build naive cells: “According to this study, it would be premature to conclude that basic immunity exists.” Many parameters must be taken into account: innate defense mechanisms, nutrition, etc .: “People are different and when a pathogen appears, each body reacts.” different. “In many cases, individual genetics also determine whether the body digest pathogens better or worse.
