'Back talk' from blood cells to their progenitors is critical to balancing blood supply
(PhysOrg.com) -- When it comes to the body's blood supply, maintaining the right balance is crucial. UCLA stem cell scientists have now discovered that in the common fruit fly, this balancing act requires a complex "conversation" ...

Direct proof of how T cells stay in 'standby' mode
the white blood cells that act as the police of the immune system—are in what immunologists call a "quiescent state," a sort of standby mode. For years, scientists have wondered if quiescence occurred by default or whether ...
