WebThe endoplasmic-reticulum (ER) stress response constitutes a cellular process that is triggered by a variety of conditions that disturb folding of proteins in the ER. Eukaryotic cells have developed an evolutionarily conserved adaptive mechanism, the unfolded protein response (UPR), which aims to clear unfolded proteins and restore ER homeostasis. WebThis results in a low pH in the tumor microenvironment that can suppress the anti-tumor immune response by inhibiting the activities of T cells and NK cells, and favoring regulatory T cell differentiation, myeloid-derived …
