An Interferon Regulated MicroRNA Provides Broad Cell-Intrinsic Antiviral Immunity through Multihit Host-Directed Targeting of the Sterol Pathway

In invertebrates, small interfering RNAs are at the vanguard of cell-autonomous antiviral immunity. In contrast, antiviral mechanisms initiated by interferon (IFN) signaling predominate in mammals. Whilst mammalian IFN-induced miRNA are known to inhibit sp ...

Role of microRNAs in tumor-associated macrophages

Tumor-associated macrophages (TAMs) infiltrate both mouse and human tumors, typically in high numbers, and display complex interactions with cancer cells, endothelial cells (ECs) and other immune cells. TAMs comprise molecularly distinct subsets. Two such ...

A Cationic Micelle Complex Improves CD8+T Cell Responses in Vaccination Against Unmodified Protein Antigen

Davide Demurtas, Jeffrey Alan Hubbell, Melody Swartz, Carrie Ellen Brubaker, Daniel Kenneth Bonner, Vasiliki Panagiotou

Nanoscale carrier platforms promote immune responses to vaccination by facilitating delivery of vaccine components to immunologically relevant sites. The technique is particularly valuable for subunit vaccination, in which coadministration of immunostimula ...

Mycobacterium tuberculosis Phosphate Uptake System Component PstA2 Is Not Required for Gene Regulation or Virulence

John McKinney, Anna De Graff Tischler

The Mycobacterium tuberculosis genome encodes two complete high-affinity Pst phosphate-specific transporters. We previously demonstrated that a membrane-spanning component of one Pst system, PstA1, was essential both for M. tuberculosis virulence and for r ...

Host genetic predictors of the kynurenine pathway of tryptophan catabolism among treated HIV-infected Ugandans

Yunfei Huang

Objective: Plasma kynurenine/tryptophan ratio, a biomarker of indoleamine 2,3-dioxygenase-1 (IDO) activity, is a strong independent predictor of mortality in HIV-infected Ugandans initiating antiretroviral therapy (ART) and may play a key role in HIV patho ...

Engineering Lymphangiogenesis

Manuel Andreas Fankhauser

Melanoma causes the vast majority of skin cancer deaths, and there is currently no conventional treatment available that is able to cure metastatic melanoma patients. However, a novel treatment modality has recently emerged: cancer immunotherapy. Cancer im ...

Type I Interferon Signaling Prevents IL-1 beta-Driven Lethal Systemic Hyperinflammation during Invasive Bacterial Infection of Soft Tissue

Alessandra Piersigilli

Type I interferons (IFN-Is) are fundamental for antiviral immunity, but their role in bacterial infections is contradictory and incompletely described. Streptococcus pyogenes activates IFN-I production in innate immune cells, and IFN-I receptor 1 (Ifnar1)- ...

Waddlia chondrophila induces systemic infection, organ pathology, and elicits Th1-associated humoral immunity in a murine model of genital infection

Alessandra Piersigilli, Joël Gyger, David Baud

Waddlia chondrophila is a known bovine abortigenic Ch/amydia-related bacterium that has been associated with adverse pregnancy outcomes in human. However, there is a lack of knowledge regarding how W chondrophila infection spreads, its ability to elicit an ...

Treatment with KLEPTOSE (R) CRYSMEB reduces mouse atherogenesis by impacting on lipid profile and Th1 lymphocyte response

Anne-Laure Gassner

The ability of pharmacological agents to target both "classical" risk factors and inflammation may be key for successful outcomes in the prevention and treatment of atherogenesis. Among the promising drugs interfering with cholesterol metabolism, we invest ...

TRIM33 switches off Ifnb1 gene transcription during the late phase of macrophage activation

Michele De Palma, Mario Leonardo Squadrito

Despite its importance during viral or bacterial infections, transcriptional regulation of the interferon-beta gene (Ifnb1) in activated macrophages is only partially understood. Here we report that TRIM33 deficiency results in high, sustained expression o ...
