The UPR is driven by three sensor proteins, namely: Inositol-Requiring Enzyme 1, Protein Kinase RNA-like ER kinase and Activating Transcription Factor 6 to restore ER homeostasis. Pathogenic infection can initiate UPR activation; some pathogens can subvert the UPR to promote their survival and replication. Many intracellular pathogens, including Leishmania, can interact and hijack ER for their survival and replication, triggering ER stress and subsequently ER stress response. This review aims to provide a comprehensive overview of the ER stress response in infections with the Leishmania species.enLeishmania speciesactivating transcription factor 6endoplasmic reticuluminositol requiring enzyme 1leishmaniasisprotein kinase RNA-like ER kinaseunfolded protein responseUnfolded protein response pathway in leishmaniasis: A reviewArticle
