Microglia,the brain's resident macrophages,help to regulate brain function by removing dying neurons,pruning non-functional synapses,and producing ligands that support neuronal *** we show that microglia are also critical modulators of neuronal activity and associated behavioural responses in *** respond to neuronal activation by suppressing neuronal activity,and ablation of microglia amplifies and synchronizes the activity of neurons,leading to *** of neuronal activation by microglia occurs in a highly region-specific fashion and depends on the ability of microglia to sense and catabolize extracellular ATP,which is released upon neuronal activation by neurons and *** triggers the recruitment of microglial protrusions and is converted by the microglial ATP/ADP hydrolysing ectoenzyme CD39 into AMP;AMP is then converted into adenosine by CD73,which is expressed on microglia as well as other brain *** sensing of ATP,the ensuing microglia-dependent production of adenosine,and the adenosine-mediated suppression of neuronal responses via the adenosine receptor A1R are essential for the regulation of neuronal activity and animal *** findings suggest that this microglia-driven negative feedback mechanism operates similarly to inhibitory neurons and is essential for protecting the brain from excessive activation in health and disease.
