Mobilizing Journalism Education

This paper evaluates several examples of integrating mobile social media within new pedagogical frameworks applied to journalism education, representing the reified activity of a journalism lecturer community of practice. We propose a mobile social media framework as a catalyst for new pedagogies that support student participation within a professional community. The framework leverages Skype and Twitter for facilitating authentic collaborative student-directed projects, establishing student eportfolios using a collage of social media, curating and critiquing mobile social media source material around news events using Storify, and the use of new and emerging collaborative mobile video applications such as Vyclone and Vine

Nitric oxide sustains IL-1β expression in human dendritic cells enhancing their capacity to induce IL-17-producing T-cells

The role played by lung dendritic cells (DCs) which are influenced by external antigens and by their redox state in controlling inflammation is unclear. We studied the role played by nitric oxide (NO) in DC maturation and function. Human DCs were stimulated with a long-acting NO donor, DPTA NONOate, prior to exposure to lipopolysaccharide (LPS). Dose-and time-dependent experiments were performed with DCs with the aim of measuring the release and gene expression of inflammatory cytokines capable of modifying T-cell differentiation, towardsTh1, Th2 and Th17 cells. NO changed the pattern of cytokine release by LPS-matured DCs, dependent on the concentration of NO, as well as on the timing of its addition to the cells during maturation. Addition of NO before LPS-induced maturation strongly inhibited the release of IL-12, while increasing the expression and release of IL-23, IL-1β and IL-6, which are all involved in Th17 polarization. Indeed, DCs treated with NO efficiently induced the release of IL-17 by T-cells through IL-1β. Our work highlights the important role that NO may play in sustaining inflammation during an infection through the preferential differentiation of the Th17 lineage
