Objective
Vertical sleeve gastrectomy (VSG) results in weight loss and increased bile acids (BA) and fibroblast growth factor 19 (FGF19) levels. FGF21 shares essential cofactors with FGF19, but its physiology early post‐VSG has not been assessed.
Methods
Ten adolescents (17.4 ± 0.5 years and BMI 51.5 ± 2.5 kg/m2) were enrolled. Fasting and postmeal (100 mL Ensure™) samples (0‐120 min) were collected...
T cell activation by dendritic cells (DCs) is critical to the initiation of adaptive immune responses and protection against pathogens. Here, we demonstrate that a specialized DC subset in Peyer's patches (PPs) mediates the rapid activation of pathogen specific T cells. This DC subset is characterized by the expression of the chemokine receptor CCR6 and is found only in PPs. CCR6 + DCs were...
Bacterial flagellins are important components of the motility apparatus used by many microbial pathogens. These proteins are also targets of the innate and adaptive immune response of the host during infection and autoimmune disease. Flagellin interacts with TLR-5 and leads to the generation of a pro-inflammatory response and activation of host dendritic cells in vivo. Furthermore, flagellin is recognized...
