Dopaminergic neuron loss in mice due to increased levels of wild-type human α-Synuclein only takes place under conditions of accelerated aging [PDF]

Scientific Reports
Understanding the intricate pathogenic mechanisms behind Parkinson's disease (PD) and its multifactorial nature presents a significant challenge in disease modeling. To address this, we explore genetic models that better capture the disease's complexity.

Post-transcriptional control of a stemness signature by RNA-binding protein MEX3A regulates murine adult neurogenesis

Nature Communications, 2023
Here the authors identify RNA-binding protein MEX3A as a post-transcriptional regulator of quiescence and differentiation signatures at critical transitions along the murine subependymal neurogenic ...
