Recent work indicates that mitochondrial ROS act via several pathways to elicit proinflammatory cytokines in human and mouse cells.
Ehninger and Trumpp discuss the role of monocytes/macrophages and other niche cells in the regulation of HSC mobilization and retention.
Brief Definitive Report
Poor prognosis after ischemic stroke or intracerebral hemorrhage is linked to a particular polymorphism in the human gene encoding p53.
Antibody-mediated gp120 shedding and HIV neutralization exhibit similar kinetics and thermodynamic requirements.
Adult mouse LSK cells unable to undergo autophagy contain fewer HSCs, accumulate mitochondria, and fail to reconstitute lethally irradiated mice.
Intratumor T helper type 2 cell infiltrate correlates with cancer-associated fibroblast thymic stromal lymphopoietin production and reduced survival in pancreatic cancer
Expression of TSLP in pancreatic cancer correlates with Th2 deviation of antitumor immunity that is associated with decrease of patient survival.
TSLP released from human breast cancer cells promotes OX40L expression on DCs, and these OX40L-expressing DCs drive development of inflammatory Th2 cells which promote breast tumor development.
IL-17 production by γδ T cells is required for tumor cell infiltration by IFN-γ–producing CD8+ T cells and inhibition of tumor growth in response to anthracyclines.
The dermis contains a novel population of γδT cells that are distinct from epidermal γδT cells and produce IL-17 in response to mycobacterial infection.
Mitochondrial reactive oxygen species promote production of proinflammatory cytokines and are elevated in TNFR1-associated periodic syndrome (TRAPS)
ROS generated by mitochondrial respiration are needed for optimal proinflammatory cytokine production in healthy cells, and are elevated in cells from patients with an autoinflammatory disorder.
Reduced miR-204 expression facilitates the excessive proliferation and apoptosis resistance of pulmonary artery smooth muscle cells characteristic of human pulmonary arterial hypertension.
Stimulation of Eph-B4 prevents adaptive remodeling and preserves venous identity when veins are surgically placed into an arterial environment.
VISTA suppresses T cell proliferation and cytokine production and can influence autoimmunity and antitumor responses in mice.
Dectin-2 expression on GM-CSF–cultured bone marrow cells is required for the generation of cysteinyl leukotrienes and Th2 cytokines in response to the house dust mite Dermatophagoides farinae in vivo.
Herpesvirus telomeric repeats facilitate genomic integration into host telomeres and mobilization of viral DNA during reactivation
Herpesvirus telomeric repeats facilitate virus integration into host telomeres, a process which is required for the establishment of virus latency.
Liver-expressed Igκ superantigen induces tolerance of polyclonal B cells by clonal deletion not κ to λ receptor editing
Analysis of tolerance in a polyclonal wild-type B cell population demonstrates apoptosis of cells reactive to antigen expressed on liver membrane.
