Three distinct developmental pathways for adaptive and two IFN-γ-producing γδ T subsets in adult thymus

Mouse γδ T cells have diverse functional subsets, but how these subsets are programmed during their development is still unclear. Here the authors show that three surface markers, CD117, CD200 and CD371, refine the development of γδ T cells in the thymus into three pathways programming distinct γδ T cell subsets

Near-normalization of glycaemic control with glucagon-like peptide-1 receptor agonist treatment combined with exercise in patients with type 2 diabetes

AIMS: To investigate the effects of exercise in combination with a glucagon‐like peptide‐1 receptor agonist (GLP‐1RA), liraglutide, or placebo for the treatment of type 2 diabetes. METHODS: Thirty‐three overweight, dysregulated and sedentary patients with type 2 diabetes were randomly allocated to 16 weeks of either exercise and liraglutide or exercise and placebo. Both groups had three supervised 60‐minute training sessions per week including spinning and resistance training. RESULTS: Glycated haemoglobin (HbA1c) levels dropped by a mean ± standard deviation of 2.0% ± 1.2% (from 8.2% ± 1.4%) in the exercise plus liraglutide group vs 0.3% ± 0.9% (from 8.0% ± 1.2%) in the exercise plus placebo group ( P < .001), and body weight was reduced more with liraglutide (−3.4 ± 2.9 kg vs −1.6 ± 2.3 kg; P < .001). Compared with baseline, similar reductions were seen in body fat (exercise plus liraglutide: −2.5% ± 1.4% [ P < .001]; exercise plus placebo: −2.2% ± 1.9% [ P < .001]) and similar increases were observed in maximum oxygen uptake (exercise plus liraglutide: 0.5 ± 0.5 L O(2)/min [ P < .001]; exercise plus placebo: 0.4 ± 0.4 L O(2)/min [ P = .002]). Greater reductions in fasting plasma glucose (−3.4 ± 2.3 mM vs −0.3 ± 2.6 mM, P < .001) and systolic blood pressure (−5.4 ± 7.4 mm Hg vs −0.6 ± 11.1 mm Hg, P < .01) were seen with exercise plus liraglutide vs exercise plus placebo. The two groups experienced similar increases in quality of life during the intervention. CONCLUSIONS: In obese patients with type 2 diabetes, exercise combined with GLP‐1RA treatment near‐normalized HbA1c levels and caused a robust weight loss when compared with placebo. These results suggest that a combination of exercise and GLP‐1RA treatment is effective in type 2 diabetes
