The susceptibility of the elderly to lung infections is due to a decrease in the number of immune cells that store information about antigens that previously acted. This was proven by the results of a study by a team of Australian scientists.

“The study showed that a significant proportion of immune cells remain stable throughout life, but the number of CD8 + T memory cells (cells that store information about antigens that act first and form a secondary immune response) decreases.” News.ru the findings of a team of researchers led by Linda Walkim of the University of Melbourne. In their view, the main reason for the vulnerability of the elderly to lung infections is the depletion of specific pathogenic T cells in the lungs, which leads to a weakening of the early antiviral immune response.
