Detects the memory memorization structure dealing with infections in the human body

According to The Daily Mail, scientists from the Medical Research Institute in Garvan, Sydney, Australia, have discovered a new structure in the human body, remembering how to fight infection and only appear when people get sick sick.

Small structures in the immune system (pink and purple) contain a large number of immune cells that appear near lymph nodes when a person starts fighting infection - (Photo: Imogen Mogan).

This structure helps explain why the body remembers how to deal with a previous infection. These are groups of cells that are responsible for planning an attack if the infection recurs.

Thanks to such cells, new vaccines can work fully when preparing to deal with possible infections. These are memory cells that contain the whole 'library' with immune information. In fact, they can turn into white blood cells, independently involved in the fight against germs.

These cell clusters are fragile with a flat structure. They appear on the lymph nodes temporarily only when we are sick. After the last infection is paid, the structures disappear until the next infection appears.
