Human Dermal CD14+ Cells Are a Transient Population of Monocyte-Derived Macrophages
Researchers demonstrate that human dermal CD14+ cells are a tissue-resident population of monocyte-derived macrophages with a short half-life of <6 days. The decline and reconstitution kinetics of human blood CD14+ monocytes and dermal CD14+ cells in vivo supported their precursor-progeny relationship. [Immunity]

PUBLICATIONS (Ranked by impact factor of the journal)
Moderate Hypoxia Potentiates Interleukin-1β Production in Activated Human Macrophages
Researchers demonstrate that hypoxia enhances pro-interleukin-1β protein, but not mRNA, expression in LPS-stimulated human macrophages. [Circ Res] Abstract

Stat3 Promotes IL-10 Expression in Lupus T Cells through trans-Activation and Chromatin Remodeling
Scientists aimed to determine molecular events governing T cell-derived IL-10 expression in health and disease. They linked reduced DNA methylation of the IL10 gene with increased recruitment of Stat family transcription factors. [Proc Natl Acad Sci USA] Abstract

Prognostic Significance of FOXP3+ Tumor Infiltrating Lymphocytes in Breast Cancer Depends on Estrogen Receptor and Human Epidermal Growth Factor Receptor-2 Expression Status and Concurrent Cytotoxic T-Cell Infiltration
FOXP3+ tumor infiltrating lymphocytes were assessed by immunohistochemistry on tissue microarrays constructed from a well-defined cohort of 3,992 breast cancer patients linked to detailed demographic, biomarker, treatment and outcome data. [Breast Cancer Res] Abstract | Full Article

Endothelial Microparticles Interact with and Support the Proliferation of T Cells
Given the recently described role for human brain microvascular endothelial cells (HBEC) in modulating immune responses, researchers investigated how HBEC-derived microparticles (MP) could interact with and support the proliferation of T cells. Like their mother cells, endothelial MP expressed molecules important for Ag presentation and T cell costimulation, that is, β2-microglobulin, MHC II, CD40, and ICOSL. [J Immunol] Abstract

TLR9 Transcriptional Regulation in Response to Double-Stranded DNA Viruses
Researchers examined the relationship between activation and the transcriptional regulation of TLR9. They demonstrate that infection of primary human epithelial cells, B cells, and plasmacytoid dendritic cells with dsDNA viruses induces a regulatory temporary negative-feedback loop that blocks TLR9 transcription and function. [J Immunol] Abstract

Cigarette Smoke Induced DAMP Release from Necrotic Neutrophils Triggers Pro-Inflammatory Mediator Release
In human peripheral blood neutrophils, mitochondrial membrane potential, apoptosis/necrosis markers, caspase activity and DAMP release were studied after cigarette smoke exposure. [Am J Respir Cell Mol Biol] Abstract

Flavonoid Apigenin Inhibits Lipopolysaccharide-Induced Inflammatory Response through Multiple Mechanisms in Macrophages
Researchers examined the effect of apigenin on LPS-induced inflammatory response and further elucidated the potential underlying mechanisms in human THP-1-induced macrophages and mouse J774A.1 macrophages. [PLoS One] Full Article

Severely Depressed Interleukin-17 Production by Human Neonatal Mononuclear Cells
Scientists examined neonatal production of IL-17 in mixed mononuclear cells isolated from umbilical cord blood for comparison with adult peripheral blood mononuclear cell controls. IL-17 production was profoundly diminished in mixed mononuclear cells isolated from cord blood when compared with mixed mononuclear cells from adult blood. [Pediatr Res] Abstract

Novel Immunotherapy Vaccine Decreases Recurrence in HER2 Positive Breast Cancer Patients
A new breast cancer vaccine candidate provides further evidence of the potential of immunotherapy in preventing disease recurrence. This is especially the case for high-risk patients when it is combined with a powerful immunotherapy drug.
