P21 Research for Age-Related Cognitive Decline
An evidence-based overview of research examining P21 in the context of age-related cognitive decline. This page synthesizes findings from peer-reviewed literature.
Research Summary
P21 has been studied for its potential effects on age-related cognitive impairment in preclinical models. Research from the Iqbal laboratory demonstrated that P21 improved spatial memory and restored synaptic markers in aged rats (Bolognin et al., 2014). Effects were associated with increased BDNF and reduced neuroinflammation. All evidence is preclinical with no human clinical trials.
