Description
Neurogenesis is the process by which new neurons are generated from neural stem and progenitor cells, and it is essential for brain development and for adult brain plasticity. The Gene Ontology term GO:0050767, regulation of neurogenesis, captures any process that modulates the frequency, rate, or extent of this neuron-generating process. Because neurogenesis must be tightly controlled in time and space, its regulation involves a complex interplay of transcriptional programs, signaling pathways, metabolic states, and non-coding RNA networks. Understanding regulation of neurogenesis is therefore central to developmental neurobiology and to regenerative medicine. Researchers study this term to identify the molecular brakes and accelerators of neuron production, to model neurodevelopmental and psychiatric disorders, and to discover targets for promoting repair in the injured or diseased nervous system. The sections below summarize the definition, mechanisms, key genes, disease links, and experimental methods used to investigate regulation of neurogenesis.

What Is GO:0050767?
According to the QuickGO definition, GO:0050767 regulation of neurogenesis refers to any process that modulates the frequency, rate, or extent of neurogenesis, which is the generation of cells in the nervous system. In practical terms, it includes both positive and negative regulation of neural stem cell proliferation, differentiation, and survival, as well as the timing and spatial restriction of neuron production.
Why Is regulation of neurogenesis Important in Cell Biology?
Regulation of neurogenesis is critically important because the balance between neural stem cell maintenance and neuronal differentiation determines brain size, circuit formation, and adult cognitive function. Disruption of this regulation can lead to neurodevelopmental disorders, while impaired adult neurogenesis is associated with depression and neurodegenerative conditions. Understanding the regulatory mechanisms provides a foundation for developing therapies that promote neuronal repair or restrain pathological proliferation.
• Controls the timing and extent of neuron production during embryonic brain development.
• Maintains adult neural stem cell pools in the hippocampal dentate gyrus and hypothalamus.
• Integrates metabolic and mitochondrial signals with stem cell fate decisions.
• Involves microRNA networks that fine-tune neural stem cell self-renewal and differentiation.
• Dysregulation is linked to depression-like behaviors and neurodevelopmental disorders.
• Provides targets for regenerative strategies in neurodegenerative disease.
• Is modulated by gut microbiota and immune signaling in preclinical models.
• Requires precise temporal control of neural stem cell competency and commitment.
• Can be studied with CRISPR-based knockout, knock-in, and overexpression models.
• Serves as a paradigm for understanding how extrinsic and intrinsic cues shape tissue generation.
What Happens During regulation of neurogenesis?
Neural stem cell competency and commitment
In simple terms: This step decides whether a stem cell stays a stem cell or becomes a committed neuron-producing cell.
Regulation of neurogenesis begins with neural stem cell competency, the state that permits a cell to respond to differentiation signals, and commitment, the transition toward a neuronal fate. During indirect neurogenesis, intermediate progenitors amplify neuron output, and their competency is controlled by transcriptional and signaling inputs. Temporal properties of neural stem cells, including the transition timing between neurogenesis and gliogenesis, are also regulated to ensure appropriate cell type production.
Mitochondrial and metabolic control
In simple terms: Mitochondria act as power plants and signaling hubs that influence whether new neurons are made.
Mitochondrial function and autophagy regulate adult hippocampal neurogenesis, linking cellular energy status to stem cell activation and neuronal differentiation. Mitochondrial regulation of adult neurogenesis has been implicated in neurological function and in neurodevelopmental disorders, suggesting that metabolic checkpoints are integral to this GO term. Autophagic regulation further modulates the survival and differentiation of newborn neurons in the healthy and diseased brain.
MicroRNA and post-transcriptional regulation
In simple terms: Small RNA molecules can dial down specific genes to control how many neurons are made.
MicroRNAs regulate neural stem cells and neurogenesis by repressing target mRNAs that control self-renewal, differentiation, and survival. This post-transcriptional layer provides rapid and reversible control of neurogenesis, allowing stem cells to respond to developmental and environmental cues.
Hypothalamic and cortical regulation
In simple terms: Different brain regions have their own rules for controlling new neuron production.
In the adult mammalian hypothalamus, neurogenesis is regulated by local signals that influence energy balance and physiological homeostasis. In the developing cortex, regulation of neurogenesis and cell proliferation in the ventral subventricular zone involves cortical signals that pattern progenitor behavior. These region-specific mechanisms illustrate the diversity of processes covered by GO:0050767.
Environmental and systemic modulation
In simple terms: Signals from the body, such as gut microbes and inflammation, can change how many new neurons are made.
Systemic factors can modulate neurogenesis; for example, rifaximin-mediated gut microbiota regulation alters microglial function and protects against chronic unpredictable mild stress-induced depression-like behaviors in adolescent rats, a process linked to neurogenesis. Such findings indicate that regulation of neurogenesis integrates peripheral physiology with central nervous system function.

How Is regulation of neurogenesis Regulated?
Regulation of neurogenesis is itself controlled by multiple intersecting pathways. Mitochondrial and autophagic regulation of adult neurogenesis in the healthy and diseased brain involves PGC-1alpha, BNIP3, and mTOR signaling, which couple energy status to stem cell fate. MicroRNAs such as miR-124 and miR-9 provide post-transcriptional control of neural stem cell self-renewal and differentiation. Temporal regulation of neural stem cell properties ensures the correct transition from neurogenesis to gliogenesis during neocortical development. Systemic signals, including gut microbiota and microglial activity, can also modulate neurogenesis in preclinical models.
regulation of neurogenesis and Human Disease
| Gene | Disease / Biology | Potential Experimental Model |
|---|---|---|
| Pgc-1alpha | Mitochondrial dysfunction in neurodevelopmental disorders | Knockout and overexpression in hippocampal neural stem cells |
| Mtor | Altered neurogenesis in depression and neurodegeneration | Conditional knockout and point-mutation models |
| Bdnf | Depression-like behaviors and impaired neuronal survival | Knock-in and overexpression in rodent brain |
| Notch1 | Cortical malformations and neurodevelopmental disorders | Knockout and point-mutation in neural progenitors |
| miR-124 | Neuronal differentiation defects | Overexpression and sponge knockdown in neural stem cells |
Neurodevelopmental disorders
Disruption of mitochondrial regulation of adult hippocampal neurogenesis has been linked to neurological dysfunction and neurodevelopmental disorders, suggesting that metabolic control of neurogenesis is relevant to disease pathogenesis. Altered temporal properties of neural stem cells can also affect cortical development and contribute to malformations.
Depression and psychiatric disorders
Rifaximin-mediated gut microbiota regulation modulates microglial function and protects against chronic unpredictable mild stress-induced depression-like behaviors in adolescent rats, a process associated with neurogenesis. This supports the hypothesis that impaired regulation of neurogenesis contributes to depression-like phenotypes.
Neurodegeneration and aging
Mitochondrial and autophagic regulation of adult neurogenesis is altered in the diseased brain, and declining neurogenesis is associated with neurodegenerative conditions. Hypothalamic neurogenesis has been proposed to influence physiological aging and metabolic homeostasis.
