Wall Street Journal has a very interesting article on Friday page A15 titled:
“The Treatment that Could Crush Covid”
about immune system components discovered 30 years ago called “medicinal signaling cells” MSC’s for short.
{I had never before heard of MSC}
Sample quote
When a MSC detects an infection or an injury to those vessels, it transforms itself into a factory to recruit and pump out immune-modulating and vessel-repair agents.
