pCLE of the extrahepatic bile duct after fluorescein injection demonstrated a reticular pattern within fluorescein-filled sinuses that had no known anatomical correlate. Freezing biopsy tissue before fixation preserved the anatomy of this structure, demonstrating that it is part of the submucosa and a ...
Tertiary lymphoid tissues also form in chronic autoimmune lesions86,87 and in the lungs after infection with influenza virus88. In the latter case, however, the formation of inducible bronchus-associated lymphoid tissues is independent of ROR-γt, so it pre- sumably does not require LTi-like ...
High-altitude hypoxia acclimatization requires whole-body physiological regulation in highland immigrants, but the underlying genetic mechanism has not been clarified. Here we use sheep as an animal model for low-to-high altitude translocation. We genera
Many believe that preservation of the native ECM structure during decellularization is highly desirable. However, because effective techniques to assess the structural damage in ECM are lacking, the disruptive effects of a decellularization method and the impact of the associated structural damage upon...
During the development of an animal, eukaryotic cells differentiate so they can perform specific functions. Groups of cells with similar specializations, and which perform a common function, are referred to as tissues. Organs (examples of which include lungs, kidneys, hearts, and spleens) are grou...
Cells in the bodies of humans and other animals are organized into types of tissues. The cells within tissues work together to perform a common function. Several tissue types work together to form an organ such as the heart, lungs, or liver. ...
[120]. Specialized tissue-resident macrophages, such as Kupffer cells in the liver, alveolar macrophages in the lungs, and histiocytes in intestinal tissue, rapidly react to perturbations in their environment and recruit other immune cells to sites of infection [120]. Although macrophages suppress ...
Human immune cells are under constant evolutionary pressure, primarily through their role as first line of defence against pathogens. Most studies on immune adaptation are, however, based on protein-coding genes without considering their cellular context
