Key result
Adoptive transfer of adult T cells into neonatal mice prolonged inflammation and inhibited myocardial regeneration in an IFN-γ-dependent manner.
Why the study?
The specific contribution of T-cell subpopulations to heart regeneration and their role in heart failure treatment remain underexplored.
Schematic showing that physiological T-cell development correlated with the loss of cardiac regenerative potential in post-natal mice, and adoptive transfer of adult T cells into neonates prolonged inflammation and inhibited myocardial regeneration in an IFN-γ-dependent manner (Dolejsi et al.6). Related to other immune cells in heart regeneration, the specific contribution of T-cell subpopulations are depicted. Dotted arrows represent possible future studies, including the converse adoptive cell transfer.
