Protein homeostasis (proteostasis) is maintained by an integrated network of physiological mechanisms and stress response pathways that regulate the content and quality of the proteome. Maintenance of cellular proteostasis is key to ensuring normal development, resistance to environmental stress, coping with infection, and promoting healthy aging and lifespan. Recent studies have revealed that several proteostasis mechanisms can function in a cell-type-specific manner within hematopoietic stem cells (HSCs). Here, we review recent studies demonstrating that the proteostasis network functions uniquely in HSCs to promote their maintenance and regenerative function.
