When aged mice were exposed to influenza, the patch provided 100% protection, compared with 75–80% protection from injected formulations.When aged mice were exposed to influenza, the patch provided 100% protection, compared with 75–80% protection from injected formulations.
Preprint: experiments in young and aged mice, against aged mice receiving an injected boostInterventions
Limit: Protection was measured after injected priming, not with the patch alone
Cell-transfer experiments in mice lacking lymphoid immune cells found that regulatory immune cells rescued regeneration inhibited by another immune-cell type.Cell-transfer experiments in mice lacking lymphoid immune cells found that regulatory immune cells rescued regeneration inhibited by another immune-cell type.
Experiments in lymphoid-deficient mutant mice, against mice receiving CD8 T cellsImmune response
Limit: The experiments did not assess how aging affects digit-tip regeneration
Experiments in kidney cells grown in the lab found that a diesel exhaust breakdown product caused lasting DNA damage and signals that activated connective-tissue cells.Experiments in kidney cells grown in the lab found that a diesel exhaust breakdown product caused lasting DNA damage and signals that activated connective-tissue cells.
A screen of 800 natural compounds identified a phytochemical that activates autophagy and restores cell-cycle activity in models of cellular exhaustion.A screen of 800 natural compounds identified a phytochemical that activates autophagy and restores cell-cycle activity in models of cellular exhaustion.
