TLDR
This review discusses the key regulatory pathways that govern translational control in response to synaptic activity and the mRNA populations that are specifically targeted by these pathways and considers the therapeutic potential of targeting dysregulated translatory control to treat cognitive disorders of synaptic dysfunction.
Abstract
Activity-dependent changes in the strength of synaptic connections are fundamental to the formation and maintenance of memory. The mechanisms underlying persistent changes in synaptic strength in the hippocampus, specifically long-term potentiation and depression, depend on new protein synthesis. Such changes are thought to be orchestrated by engaging the signaling pathways that regulate mRNA translation in neurons. In this review, we discuss the key regulatory pathways that govern translational control in response to synaptic activity and the mRNA populations that are specifically targeted by these pathways. The critical contribution of regulatory control over new protein synthesis to proper cognitive function is underscored by human disorders associated with either silencing or mutation of genes encoding proteins that directly regulate translation. In light of these clinical implications, we also consider the therapeutic potential of targeting dysregulated translational control to treat cognitive disorders of synaptic dysfunction.

The integrated stress response: From mechanism to disease

TL;DR: The integrated stress response (ISR), a central signaling network that responds to proteostasis defects by tuning protein synthesis by tuning down general mRNA translation and up-regulating the synthesis of a few proteins that drive a new transcriptional program, aims to maintain or reestablish physiological homeostasis.
