The integrated stress response (ISR) maintains proteostasis by modulating protein synthesis and is important in synaptic plasticity, learning and memory. We developed a reporter (SPOTlight) for brain-wide imaging of ISR state with cellular resolution. Unexpectedly, we found a class of neurons in mouse brains, striatal cholinergic interneurons (CINs), in which the ISR was activated at steady-state. Genetic and pharmacological manipulations revealed that ISR signaling was necessary in CINs for normal type 2 dopamine receptor (D2R) modulation. Inhibiting the ISR inverted the sign of D2R modulation of CIN firing and evoked dopamine release and altered skill learning. Thus, a non-canonical, steady-state mode of ISR activation is found in CINs and the ISR plays a neuromodulatory role in learning. Striatal cholinergic interneurons have high steady-state ISR activation that regulates dopamine modulation and skill learning.
