Characterization of the distribution and dynamics of the antigen-presenting cells using MHC II-EGFP knock-in mouse model
 Pačes, Jan ; Černý, Jan (advisor) ; Tlaskalová - Hogenová, Helena (referee)
Results of recent studies indicate that dendritic cells are capable of transporting commensal intestinal bacteria into the mammary glands, which ultimately leads to their occurrence in breast milk. We have therefore decided to evaluate the phenotype of immunologically relevant antigen presenting cells (APCs) present in the mammary glands and the small intestine, respectively and perform a comparison study. We also studied plasticity of these populations during lactation. In situ immunodetection and flow cytometry methods were used to determine phenotype. We succeeded in optimising the methods for preparation of samples for flow cytometry and microscopy. We thoroughly tested protocols for 3D visualisation of APC populations and quantitative image analysis for correlation with flow cytometry, further optimization is nevertheless needed. We found out that during lactation large numbers of MHC II+ cells cluster around the alveoli and milk ducts. These cells are of a distinctly dendritic shape and their phenotype does not correspond to the APCs in the surrounding tissue. A pronounced increase of APC cells in the mammary glands between the fourth and sixth days of lactation was observed, with the majority of these cells expressing the CD103 antigen typical for cell populations of immune cells of the...
