The emergence of immunological markers greatly accelerated the identification of the immune cells (hemocytes), while the creation of genetic reporter constructs allowed unique insight into the structural organization of hematopoietic tissues. However, investigation of the hemocyte compartments by the means of immunological markers requires dissection and fixation, which regularly disrupt the delicate structure and hamper the microanatomical characterization. Moreover, the investigation of transgenic reporters alone can be misleading as their expression often differs from the native expression pattern of their respective genes. We describe here a method that combines the reporter constructs and the immunological tools in live imaging, thereby allowing use of the array of available immunological markers while retaining the structural integrity of the hematopoietic compartments. The procedure allows the reversible immobilization of Drosophila larvae for high-resolution confocal imaging and the time-lapse video analysis of in vivo reporters. When combined with our antibody injection-based in situ immunostaining assay, the resulting double labeling of the hemocyte compartments can provide new information on the microanatomy and functional properties of the hematopoietic tissues in an intact state. Although this method was developed to study the immune system of Drosophila melanogaster, we anticipate that such a combination of genetic and immunological markers could become a versatile technique for in vivo studies in other biological systems too.}, year = {2014}, eissn = {1932-6203}, orcid-numbers = {Csordás, Gábor/0000-0001-6871-6839; Varga, Gergely István/0000-0001-9073-5788; Andó, István/0000-0002-4648-9396} } @article{MTMT:1921048, title = {Cell lineage tracing reveals the plasticity of the hemocyte lineages and of the hematopoietic compartments in drosophila melanogaster}, url = {https://m2.mtmt.hu/api/publication/1921048}, author = {Honti, Viktor and Csordás, Gábor and Márkus, Róbert and Kurucz, Judit Éva and Jankovics, Ferenc and Andó, István}, doi = {10.1016/j.molimm.2010.04.017}, journal-iso = {MOL IMMUNOL}, journal = {MOLECULAR IMMUNOLOGY}, volume = {47}, unique-id = {1921048}, issn = {0161-5890}, keywords = {Animals; Immunity, Innate; Immunity, Cellular; Receptors, Scavenger/genetics; Hemocytes/cytology/*physiology; *Hematopoiesis; Drosophila melanogaster/embryology/*immunology; Drosophila Proteins/genetics; *Cell Lineage}, year = {2010}, eissn = {1872-9142}, pages = {1997-2004}, orcid-numbers = {Csordás, Gábor/0000-0001-6871-6839; Andó, István/0000-0002-4648-9396} } @article{MTMT:1920757, title = {Sessile hemocytes as a hematopoietic compartment in drosophila melanogaster}, url = {https://m2.mtmt.hu/api/publication/1920757}, author = {Márkus, Róbert and Laurinyecz, Barbara and Kurucz, Judit Éva and Honti, Viktor and Bajusz, Izabella and Sipos, Botond and Somogyi, Kálmán and Kronhamn, J and Hultmark, D and Andó, István}, doi = {10.1073/pnas.0801766106}, journal-iso = {P NATL ACAD SCI USA}, journal = {PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA}, volume = {106}, unique-id = {1920757}, issn = {0027-8424}, year = {2009}, eissn = {1091-6490}, pages = {4805-4809}, orcid-numbers = {Laurinyecz, Barbara/0000-0003-0620-2239; Andó, István/0000-0002-4648-9396} } @article{MTMT:1915261, title = {Definition of Drosophila hemocyte subsets by cell-type specific antigens}, url = {https://m2.mtmt.hu/api/publication/1915261}, author = {Kurucz, Judit Éva and Váczi, Balázs and Márkus, Róbert and Laurinyecz, Barbara and Vilmos, Péter and Zsámboki, János and Csorba, Kinga and Gateff, E and Hultmark, D and Andó, István}, doi = {10.1556/ABiol.58.2007.Suppl.8}, journal-iso = {ACTA BIOL HUNG}, journal = {ACTA BIOLOGICA HUNGARICA (1983-2018)}, volume = {58}, unique-id = {1915261}, issn = {0236-5383}, abstract = {We analyzed the heterogeneity of Drosophila hemocytes on the basis of the expression of cell-type specific antigens.

Oil the basis of the expression or the lack of expression of blood cell antigens the following hemocyte populations have been defined: crystal cells, plasmalocytes, lamellocytes and precursor cells. The expression of the antigens and thus the different cell types are developmentally regulated. The hemocytes are arranged ill four main compartments: the circulating blood cells, the sessile tissue, the lymph glands and the posterior hematopoietic tissue. Each hemocyte compartment has a specific and characteristic composition of the various cell types.
