چکیده

The unfolded protein response (UPR) has been established as a cell-intrinsic mechanism of survival for malignant cells facing microenvironmental stressors. Recent evidence indicates that the UPR also modulates antitumor immunity. Here, we discuss the bi-faced role of the UPR as it both promotes and antagonizes antitumor T-cell immunity.

Role of Oxidative Stress in Modulating Unfolded Protein Response Activity in Chronic Myeloid Leukemia Cell Line

Background: Recently, it has been revealed that tyrosine kinase inhibitors (TKIs) act through inducing both oxidative and endoplasmic reticulum (ER) stress in chronic myeloid leukemia cells. However, ER stress signaling triggers both apoptotic and survival processes within cells. Nevertheless, mechanisms by which TKIs avoid the pro-survival effects are not clear. The aim of this study was to ev...

The Effect of Resistance Training and Berberine Chloride on the Apoptosis-Related Unfolded Protein Response Signaling Pathway in the Hippocampus of Diazinon-Poisoned Rats

Introduction: Diazinon is one of the most widely-used organophosphate pesticides in the world. This toxin enters the body in various ways and induces oxidative stress in various tissues. It has been proved that activation of unfolded protein response (UPR) under oxidative stress is a steady mechanism for maintaining cell function and survival. Therefore, the present study aimed to review the ef...

Editorial: Endoplasmic Reticulum and Its Role in Tumor Immunity

Cancer cells express surface proteins and display antigens that differ from the “norm.” These differences can be exploited to promote a therapeutic antitumor immune response. Specifically, components within the endoplasmic reticulum (ER) play a critical role in deciding which antigenic peptides are presented on the cancer cell surface to immune cells. Furthermore, under stress conditions, certa...

Antitumor Effects of HPV DNA Vaccine Adjuvanted with Beclin-1 as an Autophagy Inducer in a Mice Model

Background: There is a growing interest in development of an effective adjuvant system for improving DNA vaccines. Recent findings have confirmed an important role for autophagy in both innate and adaptive immunity. The current study was undertaken to determine the efficacy of autophagy induction with Beclin-1, as a novel adjuvant system, in mice immunized with human papilloma virus (HPV) DNA v...
