Futurology

Researchers from the University of Cambridge made a groundbreaking discovery: regulatory T cells, a type of white blood cell, form a unified large population that travels throughout the body to locate and mend damaged tissue. This challenges the conventional belief that these cells are divided into various specialized groups confined to specific areas of the body. The implications of this finding are significant for the treatment of numerous diseases, as nearly all illnesses and injuries activate the body's immune response.

It's also interesting they have tested a treatment based on this insight in mice and it has worked. That said, clinical trials can take years before human treatments become available.
