Why are older people more sensitive to coronary?

The lack of certain types of immune cells in the elderly, which are essential to combating foreign troops, can explain the vulnerability of older groups to COVID-19, say American scientists.

When germs enter the body, they cause the immune system to respond in the form of inflammation not specifically related to bacteria or viruses.

A few days later, a more accurate immune response follows that produces anti-intervention antibodies along with T cells that help produce antibodies or seek and attack infected cells.

According to the results of a study published in Cell magazine, patients with the easiest COVID-19 had a better immune response and a particularly strong T - cell response to coronary.

People over 65 are more likely to have a weaker answer to T cells and a less co-ordinated immune response to infection, wrote co-author of the Shane Crotty research from the La Jolla Institute of Immunology.

As we age, the sources of our immature T cells dry up, he explains. We have fewer T “cells experienced” that can be activated to respond to a new infection, he adds.

Aging and divulging cells may be risk-related factors that explain failure to create an answer to the unified immune system, which increases the chances of a heavier form of COVID-19, scientists say.
