Editorials
Editorial: RSV: a new box of delights for an old enemy
Discussion on potential new therapies for respiratory syncytial virus.
Editorial: Activation, functions, and generation of immunological memory in γδ T lymphocytes: lessons from nonhuman primates
Discussion of how HMBPP-deficient Listeria mutant in macaques elicits lower pulmonary trafficking of Vγ9Vδ2 T cells, as compared to the HMBPP-producing strain.
Spotlight on Leading Edge Research
Agents that increase AAM differentiation blunt RSV-mediated lung pathology
Therapeutic manipulation of macrophage differentiation to enhance the AAM phenotype may be a viable approach for ameliorating RSV-induced disease.
HMBPP-deficient Listeria mutant immunization alters pulmonary/systemic responses, effector functions, and memory polarization of Vγ2Vδ2 T cells
Role for microbial production of phosphoantigen in infection-driven responses of primate γδ T cells in vivo.
Reviews
Functional significance of mononuclear phagocyte populations generated through adult hematopoiesis
Review of key features of differentiation and function of mononuclear phagocytes, which comprise the non-resident monocyte/macrophage populations in the body.
Tissue-specific NK cell populations and their origin
Review on the phenotype and function of tissue-specific NK cells suggesting some subpopulations differentiate in situ from tissue-resident hematopoietic stem cells.
The multifaceted nature of NLRP12
Review of how pattern-recognition receptor NLRP12 are modulators of the inflammatory network during infection, cancer, and autoinflammatory disorders.
Cell Development, Differentiation, & Trafficking
Batf3-independent langerin− CX3CR1− CD8α+ splenic DCs represent a precursor for classical cross-presenting CD8α+ DCs
The absence of langerin/CD207 and CX3CR1 on splenic CD8α-positive DC identifies a functionally immature CD8α+ DC precursor, independent of Batf3 expression.
PI3K/Akt regulates survival during differentiation of human macrophages by maintaining NF-κB-dependent expression of antiapoptotic Bcl-xL
Survival of macrophages is distinctly regulated during and after differentiation.
miR-199a-5p inhibits monocyte/macrophage differentiation by targeting the activin A type 1B receptor gene and finally reducing C/EBPα expression
miR-199a-5p inhibits monocyte/macrophage differentiation via down-regulating ACVR1B, further reducing phosphorylation of Smad2/3, resulting in decreased expression of C/EBPα.
Receptors, Signal Transduction, & Genes
Human plasmacytoid dendritic cells regulate IFN-α production through activation-induced splicing of IL-18Rα
A novel IL-18Rα isoform and activation-induced splicing of IL-18Rα down-modulates IFNα production in human pDCs upon viral exposure.
Inflammation, Extracellular Mediators, & Effector Molecules
Granulocyte functions are independent of arginine availability
Granulocyte viability, phagocytosis, IL-8 secretion, chemotaxis, and antifungal activity are completely preserved in the absence of extracellular arginine.
High IP-10 levels decrease T cell function in HIV-1-infected individuals on ART
IP-10 can inhibit T cell responses in HIV-1 infected subjects on ART.
Pdcd4 modulates markers of macrophage alternative activation and airway remodeling in antigen-induced pulmonary inflammation
A role for Pdcd4 in macrophage alternative activation and airway remodeling.
Amelioration of experimental autoimmune uveoretinitis by inhibition of glyceraldehyde-derived advanced glycation end-product formation
Formation of glyceraldehyde-derived advanced glycation endoproducts contributes to the pathogenesis of endogenous uvetitis in human and animals.
Isoliquiritigenin is a potent inhibitor of NLRP3 inflammasome activation and diet-induced adipose tissue inflammation
Isoliquiritigenin, a component of Glycyrrhiza uralensis, is a potent inhibitor of the NLRP3 inflammasome, and suppresses diet-induced obesity, adipose tissue inflammation, and metabolic disorders.
The mucosal expression pattern of interferon-ɛ in rhesus macaques
The expression of INF-ɛ in multiple mucosal tissues of rhesus macaques.
Cross-talk among myeloid-derived suppressor cells, macrophages, and tumor cells impacts the inflammatory milieu of solid tumors
Interactions between MDSC, macrophages, and tumor cells alter the cytokine milieu, impacting inflammation in the tumor microenvironment.
Host Defense & Pathophysiology
NK cells kill mycobacteria directly by releasing perforin and granulysin
NK cells directly kill mycobacteria through a contactdependent mechanism leading to the release of perforin and granulysin.
Assessment of the neutrophilic antibody-dependent respiratory burst (ADRB) response to Plasmodium falciparum
Assessment of different ADRB assays to determine their suitability for the evaluation of neutrophil stimulation by antimalarial antibodies.
Divergent antiviral roles of amphibian (Xenopus laevis) macrophages elicited by colony-stimulating factor-1 and interleukin-34
Xenopus laevis CSF1 renders tadpoles and tadpole macrophages susceptible to the FV3 ranavirus, whereas IL34 increases tadpole and tadpole macrophage resistance.
Translational & Clinical Immunology
Th22 cells are expanded in multiple sclerosis and are resistant to IFN-β
Expansion of Th22 cells in multiple sclerosis could critically influence the resistance to IFN-β therapy.
Technical Advance
Technical Advance: Ascorbic acid induces development of double-positive T cells from human hematopoietic stem cells in the absence of stromal cells
In vitro human T cell development from hematopoietic stem cells in the presence and absence of feeder cells is promoted by ascorbic acid.
