Fibrinogen Protects Neutrophils from the Cytotoxic Effects of Histones and Delays Neutrophil Extracellular Trap Formation Induced by Ionomycin

Histones were rapidly lethal to neutrophils after binding to cells, but formation of fibrinogen/fibrin-histone aggregates prevented cell death.

CFTR Is a Negative Regulator of γδ T Cell IFN-γ Production and Antitumor Immunity

Investigators observed that CFTR was functionally expressed on the cell surface of γδ T cells. Genetic deletion and pharmacological inhibition of CFTR both increased IFN-γ release by peripheral γδ T cells and potentiated the cytolytic activity of these cells against tumor cells both in vitro and in vivo.

Macrophage Metabolic Reprogramming Presents a Therapeutic Target in Lupus Nephritis

Investigators found that human and mouse macrophages underwent a switch to glycolysis in response to IgG immune complex stimulation, mirroring macrophage metabolic changes in inflamed tissue in vivo. This metabolic reprogramming was required to generate a number of proinflammatory mediators, including IL-1β, and was dependent on mTOR and hypoxia-inducible factor-1α.

Nanoparticle Delivery of Immunostimulatory Oligonucleotides Enhances Response to Checkpoint Inhibitor Therapeutics

Researchers found that their engineered nanoparticles carrying a CpG DNA ligand of TLR9 could suppress tumor growth in several animal models of various cancers, resulting in an abscopal effect on distant tumors, and improving responsiveness to anti-CTLA4 treatment with combinatorial effects after intratumoral administration.

DNA of Neutrophil Extracellular Traps Promotes Cancer Metastasis via CCDC25

Investigators showed that neutrophil extracellular traps (NETs) were abundant in the liver metastases of patients with breast and colon cancers, and that serum NETs could predict the occurrence of liver metastases in patients with early-stage breast cancer.

convertibleCARs: A Chimeric Antigen Receptor System for Flexible Control of Activity and Antigen Targeting

An inert form of the human NKG2D extracellular domain (iNKG2D) was engineered as the ectodomain of the chimeric antigen receptor (CAR) to generate convertibleCARTM-T cells. These cells were specifically directed to kill antigen-expressing target cells only in the presence of an activating bispecific adapter comprised of an iNKG2D-exclusive ULBP2-based ligand fused to an antigen-targeting antibody
