A team of scientists from the Technion-Israel Institute of Technology says it's found a way that to reverse the natural aging of immune system cells — and potentially make the elderly far more resistant to COVID-19 and other infections.reports
, which the immune system uses to identify and produce antibodies against new pathogens.
"When you are young, you have young cells, and young cells have a very diverse ability to recognize anything [pathogenic] that comes into your body," Technion-Israel researcher Doron Melamed toldIn order to find a way to trick the body into making new B cells, the researchers probed one of the ways that the body naturally replenishes its supply.
The team identified the specific hormones that shut B cell production down again once stores were replenished, and realized that deactivating the hormone results in the body producing extra B cells left and right. And going forward, they hope to turn that hormonal trick into a new rejuvenating treatment for the elderly and immunocompromised.
"We found specific hormonal signals produced by the old B cells, the memory cells, that inhibit the bone marrow from producing new B cells," Melamed toldShare This Article
