A MicroRNA Upregulated in Asthma Airway T Cells Promotes TH2 Cytokine Production
Researchers identified microRNAs (miRNAs) and miRNA-regulated pathways that control the type 2 helper T cell (TH2) responses that drive pathogenic inflammation in asthma. [Nat Immunol] Abstract
Free Poster: Quick Reference for Mouse Immune Cell Frequencies and Percentages
PUBLICATIONS (Ranked by impact factor of the journal)
Age-Associated Loss of Lamin-B Leads to Systemic Inflammation and Gut Hyperplasia
The authors report that the Drosophila fat body, a major immune organ, undergoes immunosenescence and mounts strong systemic inflammation that leads to deregulation of immune deficiency signaling in the midgut of old animals. [Cell] Abstract | Graphical Abstract | Press Release

Adiposity Induces Lethal Cytokine Storm after Systemic Administration of Stimulatory Immunotherapy Regimens in Aged Mice
Researchers determined the effects of adiposity on systemic immunotherapy tolerance in aged compared with young obese mice. Young obese mice exhibited greater ratios of M1/M2 macrophages within the peritoneal and visceral adipose tissues and higher percentages of TNF+ macrophages in response to αCD40/IL-2 as compared with young lean mice. [J Exp Med] Abstract | Press Release

Interleukin 10 Modulation of Pathogenic Th17 Cells during Fatal Alphavirus Encephalomyelitis
To determine the reason for accelerated disease in the absence of IL-10, immune responses in the CNS of IL-10−/− and wild-type (WT) mice were compared. There were no differences in the amounts of brain inflammation or peak virus replication; however, IL-10−/− animals had accelerated and increased infiltration of CD4+IL-17A+ and CD4+IL-17A+IFNγ+ cells compared with WT animals. [Proc Natl Acad Sci USA] Abstract

Signaling Pathways Activated by a Protease Allergen in Basophils
Researchers characterized the cellular response activated by papain in basophils. They found that papain-induced IL-4 production requires calcium flux and activation of PI3K and nuclear factor of activated T cells. [Proc Natl Acad Sci USA] Abstract

Granzyme A Produces Bioactive IL-1β through a Nonapoptotic Inflammasome-Independent Pathway
Investigators show that the bacterial Pasteurella multocida toxin (PMT) triggers Il1b gene transcription in macrophages independently of Toll-like receptor signaling through RhoA/Rho-kinase-mediated NF-κΒ activation. Furthermore, PMT mediates signal transducer and activator of transcription protein-controlled granzyme A expression in macrophages. [Cell Rep] Full Article | Graphical Abstract

Structure and Cancer Immunotherapy of the B7 Family Member B7x
Scientists developed an in vivo system to screen therapeutic monoclonal antibodies against B7x and found that the clone 1H3 significantly inhibited growth of B7x-expressing tumors in vivo via multiple mechanisms. Furthermore, the surviving mice given 1H3 treatment were resistant to tumor rechallenge. [Cell Rep]

Non-Viral Immune Electrogene Therapy Induces Potent Antitumor Responses and Has a Curative Effect in Murine Colon Adenocarcinoma and Melanoma Cancer Models
Antitumor efficacy of electroporated proof-of-concept enhanced expression vector, coding for granulocyte-macrophage colony-stimulating factor and the B7-1 costimulatory immune molecule in growing solid tumors, was investigated and compared with a standard plasmid. [Gene Ther] Full Article

EBAG9 Modulates Host Immune Defense against Tumor Formation and Metastasis by Regulating Cytotoxic Activity of T Lymphocytes
Scientists investigated the role of estrogen receptor-binding fragment-associated antigen 9 (EBAG9) in host defense against implanted tumors in Ebag9-knockout (Ebag9KO) mice. The infiltration of CD8+, CD3+ and CD4+ T cells into the generated tumors was enhanced in Ebag9KO mice compared with controls. [Oncogenesis] Full Article
