Abstract

The airways and lungs of vertebrates are an entrance way for several microbial pathogens. Cetaceans present an upper and lower respiratory anatomy that allows the rapid flow of large air volumes, which may lead to high susceptibility to respiratory infections. Mortality and stranding rate of Cetaceans increased dramatically, so wide the knowledge about the immune system and specific antibodies identifying immune cells populations, is of fundamental importance to monitor and document cetacean health. The aim of this study was to identify the localization of dendritic cells marked by Langerin/CD207 in airways, lungs and associated lymph nodes, of the striped dolphin Stenella coeruleoalba. Samples of trachea, bronchi, lungs and lung-associated lymph nodes were obtained from a stranded adult male of Stenella coeruleoalba. Our results showed abundant lymphoid aggregates (LAs) in the lung of S. ceruleoalba. Langerhans-like dendritic cells were well distributed along the epithelium and interstitium of respiratory tract and in associated lymph nodes. The present study deepens the knowledge about the cetacean's immune system and report about the exploitability of a commercial antibody (Langerin/CD207) for cetacean species. © 2019 Elsevier GmbH
