ABSTRACT Dendritic cells (DCs) function within tissues that experience wide fluctuations in oxygen availability, and these hypoxic environments exert a strong influence on innate immune activity. In this context, we identify the Hippo pathway effector YAP1 as a central regulator of human monocyte-derived … Read more

J Leukoc Biol. 2026 Feb 9;118(2):qiaf174. doi: 10.1093/jleuko/qiaf174. ABSTRACT Neutrophils are the first responders of our innate immune system, crucial for defense against various infections. The intricate regulation of neutrophil migration is essential for neutrophil function. However, a complete mechanistic understanding is missing. We previously performed a miRNA overexpression screen and identified miR-190 as a … Read more

J Leukoc Biol. 2026 Feb 9;118(2):qiag008. doi: 10.1093/jleuko/qiag008. ABSTRACT Neutrophils are key first responders to both infectious and noninfectious stress, playing a pivotal role in maintaining homeostasis through tightly regulated activation states and the release of inflammatory mediators. The Nod-like receptor family pyrin domain containing 3 (NLRP3) inflammasome is a key regulator of inflammation and … Read more

J Leukoc Biol. 2026 Feb 4:qiag019. doi: 10.1093/jleuko/qiag019. Online ahead of print. ABSTRACT Natural killer (NK) cell antibody-dependent cellular cytotoxicity (ADCC) contributes to effective antiviral immunity, yet the relative contribution of NK cell-intrinsic factors and antibodies in mediating these responses remain poorly understood. Here, we combined functional ADCC assays with single-cell transcriptomics of peripheral NK … Read more

J Leukoc Biol. 2026 Feb 3:qiag020. doi: 10.1093/jleuko/qiag020. Online ahead of print. ABSTRACT Despite advances in engineered adaptive immune cell therapies, current options for innate immune cell therapies are sparse. In this work, we demonstrate the utility of a neutrophil progenitor-based cell therapy. Murine conditionally-immortalized neutrophil progenitors (NPs) overcome some of the hurdles of alternative … Read more

J Leukoc Biol. 2026 Jan 31:qiag016. doi: 10.1093/jleuko/qiag016. Online ahead of print. ABSTRACT Acute myeloid leukemia (AML) is characterized by profound immune dysregulation, yet the mechanisms underlying impaired cytotoxicity remain unclear. By analyzing samples from 20 AML patients and 20 healthy donors, we integrated scRNA-seq (GSE223844), bulk transcriptomes (GSE37642, GSE71014), and TCGA-AML. Single-cell profiling, BayesPrism … Read more

J Leukoc Biol. 2026 Jan 29:qiag012. doi: 10.1093/jleuko/qiag012. Online ahead of print. ABSTRACT Novel leukolectin-proteins (LL-proteins) are present in multiple lower vertebrates. LL-proteins (∼255 AAs) possess five TECPR-domains spanning 4/5 of conserved AA-sequences, and are detected in dermal lectocytes, (primitive and tissue resident) macrophages and some leukocytes. Hatched fish embryos employ secreted LL-proteins for innate … Read more

J Leukoc Biol. 2026 Jan 28:qiag014. doi: 10.1093/jleuko/qiag014. Online ahead of print. ABSTRACT Mucosal associated invariant T (MAIT) cells are part of a T cell subset that is activated upon presentation of B2 vitamin (riboflavin) metabolites by the major histocompatibility complex, class I related (MR1) protein. Though there is a clear relationship between microbial production … Read more

J Leukoc Biol. 2026 Jan 28:qiag015. doi: 10.1093/jleuko/qiag015. Online ahead of print. ABSTRACT γδ T cells are enriched at barrier sites such as skin, gut and lung, where they protect against cancer and infections, and promote healing. They detect diverse ligands in T cell receptor-dependent or independent manners, producing large quantities of pro-inflammatory cytokines. γδ … Read more
