MicroRNA Regulation in Neural Development
Summary
MicroRNAs constitute a class of small non-coding RNAs that exert precise control over gene expression during the formation and maturation of the nervous system. By binding to complementary sequences within messenger RNAs, particularly in their 3′ untranslated regions, microRNAs fine-tune protein synthesis programmes that underlie neural progenitor proliferation, neuronal differentiation, axon guidance, dendritic arborisation and synaptic refinement. In early embryonic stages, specific microRNAs govern the balance between self-renewal and lineage commitment of neural stem cells, thereby shaping the size and composition of emerging neural circuits. As neurogenesis proceeds, dynamic shifts in microRNA expression orchestrate transitions from proliferative states to post-mitotic neuronal phenotypes, modulating transcription factors and cytoskeletal regulators that determine neuronal polarity and migration. During synaptogenesis, activity-dependent microRNAs localised to dendritic compartments regulate local translation of proteins required for spine morphogenesis and long-term synaptic plasticity. Disruption of microRNA biogenesis or function has been linked to neurodevelopmental disorders, underscoring the importance of these regulators in establishing robust neural networks. Advances in high-resolution imaging and single-cell profiling continue to reveal layer- and cell-type-specific microRNA signatures, illuminating how spatial and temporal patterns of microRNA action contribute to circuit assembly, adaptive plasticity and ultimately to cognitive function.

MicroRNA Regulation in Neural Development publication trend
The graph below shows the total number of articles in microrna regulation in neural development across all publications each year (not limited to Nature Index journals).
Technical terms
microRNA: Small non-coding RNA molecules (18–25 nucleotides) that regulate gene expression post-transcriptionally, often by pairing with complementary sequences in target mRNAs to repress translation or promote degradation.
Neurogenesis: The process by which neural stem or progenitor cells divide and differentiate to generate new neurons, contributing to the formation of the nervous system during development.
Synaptic plasticity: The capacity of synapses to undergo activity-dependent strengthening or weakening, underlying learning, memory and adaptive neural circuit refinement.
3′ untranslated region (3′ UTR): The segment of an mRNA located downstream of the coding sequence, containing regulatory elements such as microRNA binding sites that influence mRNA stability and translation.
