STS2 deficiency revives CD8+T cells from exhaustion and augments checkpoint blockade efficacy in cancer immunotherapy

Background
T-cell exhaustion is a major barrier to effective antitumor immunity and limits the efficacy of cancer immunotherapies. This study investigates the role of suppressor of T-cell signaling 2 (STS2, also known as UBASH3A) in regulating CD8+ T-…

Hyperglycemia induces an immunosuppressive microenvironment in colorectal cancer liver metastases by recruiting peripheral blood monocytes through the CCL3-CCR1 axis

Background
The treatment of colorectal cancer liver metastasis (CRLM), a leading cause of mortality in patients with colorectal cancer, is complicated by type 2 diabetes (T2D). This study aimed to investigate the CRLM immune microenvironment in the co…

Cancer immunotherapy clinical trials to support urgently needed access in low- and middle-income countries: a report from the SITC global access and impact committee

Cancer is rapidly on the rise as a cause of morbidity and mortality in low- and middle-income countries (LMICs). However, despite the increasing importance of immune checkpoint inhibitors (ICIs) as a pillar of cancer therapy, access in these settings …

Reciprocal immune-epithelial interaction during breast cancer induction

The notion of immune editing and its defined phases (elimination, equilibrium, and escape), once a transformed cell emerges, is now well established. What occurs prior to, and may in fact impact, transformation—inflammation, initiation, and ince…

Tumor glyco-immunology, glyco-immune checkpoints and immunotherapy

Immunotherapy, including immune checkpoint inhibition, has transformed the prognosis of many patients with cancer. However, most patients have primary or secondary resistant tumors to currently available cancer immunotherapies. Changes in glycosylatio…
