New data highlight liver-encoded delivery of immune modulators as a strategy to mitigate age-related immune dysfunction.

Scientists hoping to discover better ways to boost immune function — which could lengthen our healthspan and protect immunocompromised patients — may have a new target, according to findings published ...
