Neuregulin 4 Downregulation Alters Mitochondrial Morphology and Induces Oxidative Stress in 3T3-L1 Adipocytes.

Neuregulin 4 (Nrg4) is an adipokine that belongs to the epidermal growth factor family and binds to ErbB4 tyrosine kinase receptors. In 3T3-L1 adipocytes, the downregulation of expression enhances inflammation and autophagy, resulting in insulin resistance. Here, we searched for the causes of this phenotype.

Wolbachia-based emerging strategies for control of vector-transmitted disease.

Dengue fever is a mosquito-transmitted disease of great public health importance. Dengue lacks adequate vaccine protection and insecticide-based methods of mosquito control are proving increasingly ineffective. Here we review the emerging use of mosquitoes transinfected with the obligate intracellular bacterium Wolbachia pipientis for vector control.

Neoantigen-specific T cell help outperforms non-specific help in multi-antigen DNA vaccination against cancer.

CD4 T helper antigens are essential components of cancer vaccines, but the relevance of the source of these MHC class II-restricted antigens remains underexplored. To compare the effectiveness of tumor-specific versus tumor-unrelated helper antigens, we designed three DNA vaccines for the murine MC-38 colon carcinoma, encoding CD8 T cell neoantigens alone (noHELP) or in combination with either "universal" helper antigens (uniHELP) or helper neoantigens (neoHELP). Both types of helped vaccines increased the frequency of vaccine-induced CD8 T cells, and particularly uniHELP increased the fraction of KLRG1 and PD-1 effector cells.

Strain belonging to an emerging, virulent sublineage of ST131 isolated in fresh spinach, suggesting that ST131 may be transmissible through agricultural products.

Food contamination with pathogenic can cause severe disease. Here, we report the isolation of a multidrug resistant strain (A23EC) from fresh spinach. A23EC belongs to subclade C2 of ST131, a virulent clone of Extraintestinal Pathogenic (ExPEC).
