Editorials
Editorial: A PHD in macrophage survival
Discussion of how PHD3 regulates macrophage survival.
Editorial: The contribution of myeloid-derived suppression to inflammatory disease
Discussion on the role of Ly6Chigh myeloid cells in suppressing inflammation during colitis.
Spotlight on Leading Edge Research
Prolyl-4-hydroxylase domain 3 (PHD3) is a critical terminator for cell survival of macrophages under stress conditions
PHD3 influences apoptotic cell survival decisions in macrophages by altered production of Angiopoietin-like protein 2.
Immunosuppressive monocytes: possible homeostatic mechanism to restrain chronic intestinal inflammation
Inflammatory monocytes recruited into chronically inflamed intestines become immunosuppressive, inhibit T cell activation and polarization toward Th1 phenotype, but promote generation of regulatory T cells.
Reviews
Respiratory viral infection, epithelial cytokines, and innate lymphoid cells in asthma exacerbations
Review of how viral infection of airway epithelial cells leading to release of Th2-promoting cytokines may drive asthma exacerbations via activation of innate lymphoid cells.
Cell Development, Differentiation, & Trafficking
Inflammation programs self-reactive CD8+ T cells to acquire T-box-mediated effector function but does not prevent deletional tolerance
T-box transcription factor expression enables effector differentiation of self-reactive T cells upon antigen engagement, but fails to prevent their deletion.
Receptors, Signal Transduction, & Genes
The histamine H4 receptor is a potent inhibitor of adhesion-dependent degranulation in human neutrophils
The presence of a functional histamine H4 receptor in neutrophils with anti-inflammatory properties.
The Cebpa +37-kb enhancer directs transgene expression to myeloid progenitors and to long-term hematopoietic stem cells
The Cebpa +37-kb enhancer directs preferential expression to myeloid, as compared to megakaryocyte/erythroid or lymphoid progenitors, and to functional long-term hematopoietic stem cells.
The TLR signaling adaptor TRAM interacts with TRAF6 to mediate activation of the inflammatory response by TLR4
TRAM interaction with TRAF6 regulates the inflammatory response to TLR4 activation, and adds further intricacy to TLR signaling.
L-plastin is involved in NKG2D recruitment into lipid rafts and NKG2D-mediated NK cell migration
L-plastin participates in NKG2D clustering and NKG2D-mediated inhibition of NK cell chemotaxis.
Inflammation, Extracellular Mediators, & Effector Molecules
Drug analog inhibition of indoleamine 2,3-dioxygenase (IDO) activity modifies pattern recognition receptor expression and proinflammatory cytokine responses early during influenza virus infection
Inhibition of IDO activity with 1MT treatment following influenza infection enhances the production of IL-6, TNF-α, IL-1β, and IFN-β through modulation of macrophages.
N-Octanoyl dopamine transiently inhibits T cell proliferation via G1 cell-cycle arrest and inhibition of redox-dependent transcription factors
N-octanoyl dopamine displays transient T cell suppressive activity by preventing NFκB and AP-1 activation, and acts synergistically with calcineurin inhibitors on T cell proliferation.
An essential role of interleukin-17 receptor signaling in the development of autoimmune glomerulonephritis
Blocking IL-17R signaling may be a promising therapeutic strategy for the treatment of proliferative and crescentic glomerulonephritis.
Host Defense & Pathophysiology
Characterization of lung inflammation and its impact on macrophage function in aging
Age associated lung inflammation can modify pulmonary macrophage function, which can be reversed with an ibuprofen supplemented diet.
