Siegel Lab Identifies TL1A As a Novel Cytokine that Contributes to IL-9-mediated Allergic Disease

New research from the Autoimmunity Branch reveals that TL1A-DR3 interactions contribute to the production of IL-9-secreting T cells and development of allergic lung inflammation. This study identifies the therapeutic potential of targeting TL1A for the treatment of IL-9-mediated allergic diseases. The image shows mucus in the airway (top right) and TL1A around the blood vessels (bottom right) of inflamed lung compared to healthy lung (left).

SIRT1 Links Metabolism to Gene Expression in Skeletal Muscle Stem Cells

Sirtuin 1 (SIRT1) is an enzyme that regulates gene expression by removing acetyl groups from DNA-associated proteins. New research from the Sartorelli lab reveals that metabolic changes affect SIRT1 activity, thus leading to altered gene expression in the stem cells of skeletal muscle.
