Researchers at Salk Institute establish a novel framework for the relationship between nutrition and cell identity. They found that a nutritional switch from acetate to citrate plays a key role in determining T cell fates, shifting them from active effector cells to exhausted cells.
New research from the University of Pittsburgh found that opioids can suppress the immune system and reduce the effectiveness of immunotherapy for head and neck cancer. However, peripherally restricted OPRM1 antagonists (PAMORAs) may block opioid-induced immunosuppression and improve response rates to immune checkpoint inhibitor therapy.
A recent study found a correlation between higher anti-PD-1 autoantibody levels and lower survival rates in patients with advanced liver cancer, suggesting these autoantibodies as potential biomarkers for predicting treatment response. The discovery aims to improve treatment regimens for patients with liver cancer.
A study by IRB Barcelona researchers has identified five independent factors that determine patients' response and survival after receiving checkpoint inhibitors, a type of immunotherapy. These findings provide a framework for current and future biomarkers of immunotherapy response and could lead to more accurate patient classification.
