Shh production and Gli signaling is activated in vivo in lung, enhancing the Th2 response during a murine model of allergic asthma

The pathophysiology of allergic asthma is driven by T-helper 2 (Th2) immune responses following aeroallergen inhalation. The mechanisms that initiate, potentiate and regulate airways allergy are incompletely characterized. We have previously shown that Hedgehog (Hh) signaling to T-cells, via downstream Gli transcription factors, enhances T-cell conversion to a Th2 phenotype. Here, we show for the first time that Gli-dependent transcription is activated in T-cells in vivo during murine allergic airways disease (AAD) a model for the immunopathology of asthma; and that genetic repression of Gli signaling in Tcells decreases the differentiation and/or recruitment of Th2 cells to the lung. We report that T-cells are not the only cells capable of expressing activated Gli during AAD. A substantial proportion of eosinophils and lung epithelial cells, both central mediators of the immunopathology of asthma, are also able to undergo Hh/Gli signaling. Finally, we show that Shh increases Il4 expression in eosinophils. We therefore propose that Hh signaling during AAD is complex, involving multiple cell types, signaling in an auto- or paracrine fashion. Improved understanding of the role of this major morphogenetic pathway in asthma may give rise to new drug targets for this chronic condition

Exploring the feasibility of a cluster pilot randomised control trial to improve children’s 24-hour movement behaviours and dietary intake:happy homework

We aimed to explore the feasibility, acceptability, and potential efficacy of Happy Homework (HH); an 8-week home-focussed intervention, with the purpose of encouraging children’s positive dietary behaviours and engagement in positive physical activity (PA) and sleep behaviours. We randomised four Scottish schools (n = 71 participants; 5 classrooms) to either the HH intervention (n = 2) or usual curriculum control group (n = 2). HH consisted of movement and dietary-focused parent and child tasks. Primary outcome measures were intervention feasibility, acceptability, and potential efficacy. Secondary outcomes were objectively measured PA via ActiGraph GT3X+, sedentary behaviours (SBs) and sleep duration via activPAL4™ accelerometers and dietary behaviours, fruit and vegetable consumption and screen-time via questionnaires. After controlling for pre-test levels, post intervention stepping time and sleep duration were significantly greater for the HH group in comparison to the control group. The HH group reported eating more fruit and vegetables at post-test than the control group. Participants also reported the intervention to be enjoyable and motivating. These findings provide promising evidence that given a greater sample size, better retention and the prioritisation of health and wellbeing homework, HH could enhance children’s health and wellbeing
