PCNA at the crossroads of human neutrophil activation, metabolism, and survival
The proliferating cell nuclear antigen scaffold differentially binds hexokinase, procaspase-9, and p47phox to regulate neutrophil metabolism, viability and activation state.

G-CSF reshapes the cytosolic PCNA scaffold and modulates glycolysis in neutrophils
G-CSF changes the PCNA scaffold, affecting interactions with key glycolytic enzymes and thereby regulating glycolysis in neutrophils.
Reviews
Panton-Valentine leukocidin–induced neutrophil extracellular traps lack antimicrobial activity and are readily induced in patients with recurrent PVL + -Staphylococcus aureus infections
Panton-Valentine leukocidin induces nonlethal extracellular traps in neutrophils, which may serve as an evasion strategy of PVL-producing S. aureus.
Effector and cytolytic function of natural killer cells in anticancer immunity
The intratumoral function of natural killer cells is sensitive to the tumor microenvironment and controls its phenotype and cytolytic function. We discuss how molecular interactions drive the function of natural killer cells.

Phenotypic alteration by dengue virus serotype 2 delays neutrophil apoptosis and stimulates the release of prosurvival secretome with immunomodulatory functions
Neutrophil–DV-2 interaction modulates the phenotype and effector functions of neutrophils that may have both beneficial and detrimental effects.
Reprogramming of human γδ T cells by expression of an anti-CD19 TCR fusion construct (εTRuC) to enhance tumor killing
NKG2D receptor signaling shapes T cell thymic education
NKG2D impacts thymic T cell development at a fundamental level by reducing the TCR components and affecting the functional imprint of the thymic progeny.
Macrophage-expressed SRA ameliorates alcohol-induced liver injury by suppressing S-glutathionylation of Notch1 via recruiting thioredoxin
Our study revealed that SRA plays a critical role in macrophage inflammatory response by targeting Notch1 for its glutathionylation, and SRA-mediated negative regulation of Notch activation might serve as a novel therapeutic strategy for alcohol-induced liver injury.
NKG2A discriminates natural killer cells with a suppressed phenotype in pediatric acute leukemia
In this study, we have prospectively analyzed natural killer cell function and phenotype in matched blood and bone marrow samples from precursor B cell acute lymphoblastic leukemia patients at diagnosis and throughout treatment.
Coculturing liver cancer cells and monocytes in spheroids conditions monocytes to adopt tumor-associated macrophage phenotypes that favor tumor growth via cholesterol metabolism
In this study, 3-dimensional liver cancer spheroids incorporating human primary monocytes were used to investigate the crosstalk between tumor-associated macrophages. The results identified the cholesterol metabolism pathway as a major pathway that drives the macrophages to adopt protumor phenotypes. Inhibiting a key enzyme in this pathway in cancer spheroid-infiltrating macrophages reduces tumor growth and invasive phenotypes.
Bacteria- and fungus-derived PAMPs induce innate immune memory via similar functional, metabolic, and transcriptional adaptations
Structurally dissimilar ligands of diverse origin that induce distinct changes in transcription and metabolism in macrophages can converge toward common pathways to enhance antimicrobial responses.
The effect of leptin on trained innate immunity and on systemic inflammation in subjects with obesity
Leptin has an effect on systemic inflammation and innate immune cell function in the context of obesity in vitro and in vivo.
A novel opsonic eCIRP inhibitor for lethal sepsis
MFG-E8–derived oligopeptide 3 promotes the clearance of a new damage-associated molecular pattern, extracellular cold-inducible RNA-binding protein, by macrophages through αvβ3-integrin to attenuate acute lung injury and mortality in polymicrobial sepsis.
Brief Report
Single-cell transcriptomics reveal different maturation stages and sublineage commitment of human thymic invariant natural killer T cells
Human thymus contains different maturation stages of invariant natural killer T cells and facilitates sublineage commitment with invariant natural killer T2 properties in the most immature cells and an invariant natural killer T1 signature in the more differentiated clusters.
