Mitochondrial-targeted SS-31 peptide ameliorates mitochondrial dysfunction and rescues pre-existing cardiac dysfunction in old mice, supporting the translational potential of mitochondrial protective interventions to treat age-related diseases.
Changes to cellular protein homeostasis reveal widespread advantageous effects of destabilizing mutations, opening the possibility to switch mutational landscapes back-and-forth from permissive to restrictive.
The new drug 3,6’-dithiopomalidomide mitigates key markers of neuronal death and neuroinflammation and improves acute behavioral outcome measures in traumatic brain injury, a common, debilitating disorder that lacks effective treatment.
