It has strong cytoprotective effects mediated mainly through specific PAC1 receptors. Experimental data show protective effects of PACAP in the retina and cornea in several pathological conditions. Although intravitreal injections are a common practice in some ocular diseases, delivery of therapeutic agents in the form of eye drops would be more convenient and would lead to fewer side effects. We have previously shown that PACAP, in the form of eye drops, is able to pass through the ocular barriers and can exert retinoprotective effects. As eye drops represent a promising form of administration of PACAP in ocular diseases, it is important to investigate the stability of PACAP in solutions used in eye drops. In this study, the stability of PACAP1-27 and PACAP1-38 in eye drops was measured in four common media and a commercially available artificial tear solution at both room temperature and +4 °C. Mass spectrometry results show that the highest stability was gained with PACAP1-38 in water and 0.9% saline solution at +4 °C, representing 80–90% drug persistence after 2 weeks. PACAP1-38 in the artificial tear showed very fast degradation at room temperature, but was stable at +4 °C. In summary, PACAP1-38 has higher stability than PACAP1-27, with highest stability at +4 °C in water solution, but both peptides in each medium can be stored for relatively longer periods without significant degradation. These data can provide reference for future therapeutic use of PACAP in eye drops.}, year = {2021}, eissn = {1559-1166}, pages = {1567-1574}, orcid-numbers = {Kovács, Anita Kármen/0000-0001-9805-1647; Atlasz, Tamás/0000-0002-8112-8633; Werling, Dóra/0000-0003-0796-7997; Szabó, Edina/0000-0002-0653-9547; Reglődi, Dóra/0000-0001-5481-5529; Tóth, Gábor/0000-0002-3604-4385} } @article{MTMT:31385279, title = {Imidazo[1,2-b]pyrazole-7-Carboxamide Derivative Induces Differentiation-Coupled Apoptosis of Immature Myeloid Cells Such as Acute Myeloid Leukemia and Myeloid-Derived Suppressor Cells}, url = {https://m2.mtmt.hu/api/publication/31385279}, author = {Kotogány, Edit and Balog, József Ágoston and Nagy, Lajos I. and Alföldi, Róbert and Bertagnolo, Valeria and Brugnoli, Federica and Demjén, András and Kovács, Anita Kármen and Batár, Péter and Mezei, Gabriella and Szabó, Renáta and Kanizsai, Iván and Varga, Csaba and Puskás, László and Szebeni, Gábor}, doi = {10.3390/ijms21145135}, journal-iso = {INT J MOL SCI}, journal = {INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, volume = {21}, unique-id = {31385279}, issn = {1661-6596}, year = {2020}, eissn = {1422-0067}, orcid-numbers = {Kovács, Anita Kármen/0000-0001-9805-1647; Varga, Csaba/0000-0002-2678-665X; Szebeni, Gábor/0000-0002-6998-5632} } @article{MTMT:31143380, title = {Single Cell Mass Cytometry Revealed the Immunomodulatory Effect of Cisplatin Via Downregulation of Splenic CD44+, IL-17A+ MDSCs and Promotion of Circulating IFN-γ+ Myeloid Cells in the 4T1 Metastatic Breast Cancer Model.}, url = {https://m2.mtmt.hu/api/publication/31143380}, author = {Balog, József Ágoston and Hackler, László and Kovács, Anita Kármen and Neuperger, Patricia and Alföldi, Róbert and Nagy, Lajos István and Puskás, László and Szebeni, Gábor}, doi = {10.3390/ijms21010170}, journal-iso = {INT J MOL SCI}, journal = {INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, volume = {21}, unique-id = {31143380}, issn = {1661-6596}, abstract = {The treatment of metastatic breast cancer remained a challenge despite the recent breakthrough in the immunotherapy regimens. Here, we addressed the multidimensional immunophenotyping of 4T1 metastatic breast cancer by the state-of-the-art single cell mass cytometry (CyTOF). We determined the dose and time dependent cytotoxicity of cisplatin on 4T1 cells by the xCelligence real-time electronic sensing assay. Cisplatin treatment reduced tumor growth, number of lung metastasis, and the splenomegaly of 4T1 tumor bearing mice. We showed that cisplatin inhibited the tumor stroma formation, the polarization of carcinoma-associated fibroblasts by the diminished proteolytic activity of fibroblast activating protein. The CyTOF analysis revealed the emergence of CD11b+/Gr-1+/CD44+ or CD11b+/Gr-1+/IL-17A+ myeloid-derived suppressor cells (MDSCs) and the absence of B220+ or CD62L+ B-cells, the CD62L+/CD4+ and CD62L+/CD8+ T-cells in the spleen of advanced cancer. We could show the immunomodulatory effect of cisplatin via the suppression of splenic MDSCs and via the promotion of peripheral IFN-γ+ myeloid cells.

This work describes the optimized synthesis of an N-peptide-6-amino-d-luciferin conjugate (Fmoc-Gly-Pro-6-amino-d-luciferin) with a simple fragment condensation method in adequate yields. Fmoc-Gly-Pro-6-amino-d-luciferin was produced from a previously synthesized Fmoc-Gly-Pro-OH and also previously synthesized 6-amino-2-cyanobenzothiazole with an optimized method, to which conjugate cysteine was added in an also improved way. The resulting conjugate was successfully used in a bioluminescent system, in vitro, demonstrating the applicability of the method.
