This study utilized induced pluripotent stem cell (iPSC)-derived neurons to investigate the critical role of lysosome-related vesicles in axonal mRNA transport and mitochondrial homeostasis maintenance. By knocking out BORC subunits (borcs5 or borcs7) to block the entry of lysosome-related vesicles into axons, researchers found that this led to a s...

The transcription factor Meis2 promotes the development of projection neurons during mouse embryonic development by binding to and activating projection neuron-specific enhancers with Dlx5

This study investigated the role of the transcription factor Meis2 in regulating the development and differentiation of γ-aminobutyric acid (GABA)ergic neurons during mouse embryonic development. Researchers comprehensively applied techniques such as CRISPR/Cas9 knockdown, single-cell RNA sequencing (scRNA-seq), and lineage tracing, and found that ...
