The axon initial segment-associated microglia regulate neuronal activity and visual perception
This groundbreaking research identifies a novel population of microglia specifically associated with neuronal axon initial segments (AISs). These AISa-microglia directly regulate neuronal activity and visual perception through a unique THIK-1 potassium channel-mediated mechanism. Their transient depolarization, triggered by visual stimulation via muscarinic receptors, leads to K+ release and subsequent modulation of neuronal firing and coordinated neural ensemble activity. Disrupting this interaction significantly impairs visual discrimination behavior in awake mice. This highlights a critical, previously unknown role for direct microglia-neuron functional interaction in higher-order brain functions.

Microglia are identified as direct regulators of neuronal activity, with a specific subpopulation (AISa-MGs) associating with axon initial segments (AISs). These cells exhibit distinct morphological and transcriptomic profiles. The study reveals that AISa-MGs undergo transient depolarizations in response to visual stimuli, mediated by muscarinic receptors and NALCN channels, and then release K+ via THIK-1 channels to modulate neuronal firing.
The research demonstrates that brief depolarization of AISa-MGs promotes action potential firing in associated neurons by releasing K+ through THIK-1 channels. This K+ release causes a sub-threshold depolarization at the neuronal AIS, enhancing excitability. Disruption of microglial THIK-1 activity or the AIS-microglia interaction impairs neuronal calcium responses and coordinated neural ensemble activity, providing a direct link between microglial state and neuronal firing.
The study shows that the AIS-microglia functional interaction is crucial for visual perception. In vivo visual stimulation triggers robust calcium responses in neurons associated with AISa-MGs, which are disrupted when microglial depolarizing activity or THIK-1 function is inhibited. This ultimately affects visual discrimination behavior in awake mice, suggesting that these microglia-neuron interactions are critical for higher-order brain functions, including sensory processing and cognitive tasks.
