The cover shows a fluorescent microscopic image of a precision cut lung section with CD103⁺ dendritic cells (red), SIRP-1a⁺ dendritic cells and alveolar macrophages (magenta), and E-cadherin⁺ epithelial cells (green). Thomas et al., found that MyD88 gene expression in lung dendritic cells is controlled by cellintrinsic and -extrinsic MyD88 signaling, and that these different signals orchestrate immune responses to inhaled allergens. Image was provided by Seddon Y. Thomas, Miranda R. Lyons-Cohen, and Donald N. Cook, Immunity, Inflammation, and Disease Laboratory, NIEHS, NIH.
