In the March 2023 issue of Science Immunology, researchers working at the City of Hope National Medical Center reported on the discovery the mechanisms by which the spliced X-box–binding protein 1 (XBP1s) served essential functions in the IL-15-dependent survival of natural killer (NK) cells. Since XBP1s is known to play critical roles in MHCII expression, the unfolded protein stress response, and ultimately tumorigenesis, the study provided deep insights into the understanding of NK cell biology with translational potential.
The traps that neutrophils develop against microorganisms also hold T cells and prevent the success of immunotherapy in pancreatic cancer. To free the immune system from itself, scientists at the Istituto Oncologico Veneto in Italy made a key that unlocked this sticky dungeon from an antibody against arginase-1 (ARG1), an enzyme also present in the trap.
Eureka Therapeutics Inc. has entered into a license agreement with the National Cancer Institute (NCI) to develop and commercialize a novel antibody targeting mesothelin (MSLN) in combination with Eureka's proprietary Artemis T-cell receptor platform.
Limited data exist on checkpoint inhibition that targets the early activation phase of adaptive immunity. B-and T-lymphocyte attenuator (BTLA) blockade is known to enhance and broaden CD8+ T-cell responses to a target antigen.
Researchers from Memorial Sloan Kettering Cancer Center and affiliated organizations presented data from a study that aimed to investigate the immunomodulatory functions of lysine-specific demethylase 1 (LSD1) in regulating MHC-I antigen presentation pathway (APP) and resistance to immunotherapy in patients with small-cell lung cancer (SCLC).
