| 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. [Nature] |

|
| The authors developed human cytokine-inducible SH2-containing protein-knockout (CISH−/−) NK cells using an induced pluripotent stem cell-derived NK cell (iPSC-NK cell) platform. CISH−/− iPSC-NK cells demonstrated increased IL-15-mediated JAK-STAT signaling activity. [Cell Stem Cell] |
|
|
|
| Researchers identified transcriptionally distinct malignant subpopulations and compared their drug-response and genomic profiles. Malignant subpopulations from the same patient responded strikingly differently to anti-cancer drugs ex vivo, which recapitulated subpopulation-specific drug sensitivity during in vivo treatment. [Nature Cell Biology] |

|
|
| Scientists showed that effector T cells could utilize inosine, as an alternative substrate, to support cell growth and function in the absence of glucose in vitro. T cells metabolized inosine into hypoxanthine and phosphorylated ribose by purine nucleoside phosphorylase. [Nature Metabolism] |
|
|
|
| Researchers characterized the impact of a variant on cytokine signaling in vitro using transfected cell lines as well as primary patient-derived cells and supported these findings using a mouse model with the corresponding genome-edited variant Il6st p.R279Q. [Bone Research] |
|
|
|
| Investigators demonstrated that recruitment of the NF-κB factor RELA to intragenic regions regulated alternative splicing upon NF-κB activation by the viral oncogene tax of HTLV-1. [Nature Communications] |
|
|
|
| Scientists investigated the phagocytosis of rod-shaped polymeric particles by human neutrophils relative to other leukocytes. In contrast to macrophages and other mononuclear phagocytes, neutrophils were found to exhibit increased internalization of rods in ex vivo and in vivo experimentation. [Science Advances] |
|
|
|
| The authors infused expanded, activated autologous natural killer cells to potentiate trastuzumab-mediated antibody-dependent cell cytotoxicity in patients with HER2-positive malignancies. [Gene Therapy] |
|
|
|
| Investigators demonstrated that deletion of CD56 on the NK92 cell line led to impaired cytotoxic function. CD56-knockout cells failed to polarize during immunological synapse formation and have severely impaired exocytosis of lytic granules. [eLife] |
|
|
|
| The authors created a chimeric antigen-receptor (CAR) that was capable of on-demand downregulation by fusing the CAR to a previously developed ligand-induced degradation domain. Addition of a small molecule ligand triggered exposure of a cryptic degron within the ligand-induced degradation domain (LID), resulting in proteasomal degradation of the CAR-LID fusion protein and loss of CAR on the surface of T cells.

|
|
| In order to deliver protection against viral pathogens and allow at the same time necessary steroid therapy, scientists generated glucocorticoid-resistant T cells by CRISPR/Cas9-mediated knockout of the glucocorticoid receptor in primary human virus-specific T-cell products. [Molecular Therapy] |
|
|
|
| Researchers showed that circulating tumor cells isolated from immunotherapy-resistant metastatic melanoma patients expressed higher levels of nuclear lysine specific demethylase 1 (LSD1) phosphorylated at serine 111 compared to responders, which is associated with co-expression of stem-like, mesenchymal genes.

|
| MYC+ cells accounted for 21% and 18% of CD68+ and CD163+ cells, respectively. Numbers of MYC− macrophages were significantly higher in EBV+ cases while no differences were observed for MYC+ macrophages between EBV+ and EBV− cases. [Scientific Reports] |

|
|
| Investigators summarize and question what is known and remains to be discovered about the TREM2 signaling pathway, track the consequences of its activation in physiological niches and pathological contexts, and highlight the promising potential of therapeutic manipulation of TREM2 signaling. [Cell] |
|
|
|
| The authors review the antitumor roles of the GMP-AMP synthase (cGAS-STING) pathway during tumorigenesis, cancer immune surveillance, and cancer therapies. They also highlight classic cancer therapies that elicit antitumor immune responses through cGAS activation. [Cell Research] |
|
|
|
| Scientists summarize the roles and mechanisms of exosomes in the interaction between tumor cells and macrophages and the potential methods by which exosomes are used to target the communication between tumor cells and macrophages to treat cancer. [Molecular Therapy] |

| The University of California (UC) system announced it has signed the biggest open-access deal in North America with one of the largest commercial scientific publishers. The agreement with Springer Nature includes a commitment by the publisher to explore making all articles that UC corresponding authors publish in the Nature family of journals immediately free to read on publication starting in 2022.

|
| City of Hope signed an exclusive, worldwide licensing agreement with Scopus BioPharma Inc. Scopus will further develop and plans to commercialize a City of Hope first-in-class, targeted immuno-oncology gene therapy. [City of Hope] |
