lungs–lungs will ‘remember‘ infection Covid-19. So what impact will it have on system immunity from lungs–lungs?
LENGKONG, AYOBANDUNG.COM – A new study of survivors Covid-19 show lungs–lungs ‘remember‘ infection Covid-19 and store it in T cells and B cells (part of system immunity) and the surrounding lymph nodes lungs–lungs.
According to the study’s authors, George H. Humphreys II Professor of Surgery named Donna Farber, Ph.D., identified the source of memory system immunity to infection SARS-CoV-2 is important because it can lead to vaccine upgrades or booster vaccines.
Medical Xpress reports that researchers found germinal centers, where antibody-producing B cells and B memory cells are located, in lymph nodes around lungs–lungs for six months after infection, even in elderly survivors.

In addition, they also found that SARS-CoV-2-specific germinal center B cells and follicular-helper T cells (T cells that promote B cell differentiation) remained in the same place.
This is proof that system immunity from lungs–lungs survive after infection Covid-19. The survival of these germinal center B cells ensures the long-term presence of antibodies and continued maturation of the immune response.
So, system immunity on survivors Covid-19 will form a memory immunity from infection new pathogens, even in elderly survivors.
That is, the findings also suggest that the vaccine is likely to produce a more potent immune response in the elderly than previously thought.
