Light exposure can affect embryonic development through a direct toxic effect on the embryo via the generation of reactive oxygen species. In a previous study, we demonstrated the positive effect of improved light-protected embryo culture conditions implemented in our laboratory. This study aimed to investigate the changes in human embryo development under light protection during the conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Materials and Methods: We tested the potential beneficial effect of light filters to reduce the risk of toxic effects of light. IVF outcomes were compared between two experimental conditions, light protection with red light filters versus no light protection as a control. Results: Blastocyst development rate in IVF was significantly higher in the light-protected group than in the group treated under conventional conditions (46.6 vs. 26.7%). In the case of ICSI, we obtained a similar result (44.5 vs. 31.6%). The rate of cryopreservation with at least one embryo was higher in the light-protected phase (32.8%) than in the conventionally manipulated phase (26.8%). The abortion rate was also significantly lower during the light-protected period in IVF, resulting in a higher live birth rate. Conclusions: The implementation of light protection to reduce the embryotoxic wavelengths of light in IVF centers may improve the blastocyst development rate and embryo quality while maintaining embryo safety.}, keywords = {blastocyst; abortion; intracytoplasmic sperm injection; In vitro fertilization; Live birth rate; light protection}, year = {2024}, eissn = {1423-0151}, orcid-numbers = {Herczeg, Róbert/0000-0002-5903-0082; Kovács, L.

During pregnancy, the maternal immune system uses different tolerance mechanisms to deal with a semi-allogenic fetus. The expression of immune checkpoints and their related miRNAs in immune cells can ensure pregnancy at the feto-maternal interface by modulating immune responses. This study aims to evaluate the expression of the immune checkpoint molecules PD-1 and Tim-3 on circulating T cells by flow cytometry, that of mir-138 and mir-155 in PBMCs by Real-time PCR, and the concentrations of TGF-β and IP-10 in the sera of women suffering from RPL as well as of gestational age-matched healthy pregnant women by ELISA. The percentage of PD-1 or Tim-3 expressing CD8+ T cells was significantly lower in RPL patients compared to the controls, while there was no significant difference in Tim-3 expression of CD4+ T cells between the two groups. The mRNA of both the PD-1 and Tim-3 genes were downregulated in PBMCs of RPL patients compared to controls, however, the the difference was not statistically significant for Tim-3. The concentration of TGF-β was significantly lower and that of IP-10 was significantly higher in the sera of RPL patients than in those of the controls. The relative expression of mir-138 and miR-155 were significantly lower, in PBMCs of RPL patients than in those of healthy pregnant women. These data confirm that by affecting cytokine production, immune checkpoints, and microRNAs play a role in establishing the appropriate local immune environment for successful pregnancy. The wider analysis of immune checkpoints may also yield new biomarkers for the diagnosis and prevention of RPL.}, keywords = {PD-1; Recurrent pregnancy loss; TIM-3}, year = {2024}, eissn = {1879-0542} } @article{MTMT:34214976, title = {The effect of Calcitriol on the development and implantation capacity of embryos from hyper-stimulated mice}, url = {https://m2.mtmt.hu/api/publication/34214976}, author = {Bognar, Zoltan and Csabai-Tanics, Timea J. and Gorgey, Eva and Miko, Eva and Szekeres, Júlia}, doi = {10.1016/j.jri.2023.104060}, journal-iso = {J REPROD IMMUNOL}, journal = {JOURNAL OF REPRODUCTIVE IMMUNOLOGY}, volume = {159}, unique-id = {34214976}, issn = {0165-0378}, keywords = {immunology}, year = {2023}, eissn = {1872-7603}, pages = {27-27} } @article{MTMT:34212243, title = {The effect of Calcitriol on oocyte and embryo development mice}, url = {https://m2.mtmt.hu/api/publication/34212243}, author = {Bognar, Zoltan and Csabai-Tanics, Timea Judith and Gorgey, Eva and Szekeres, Júlia}, doi = {10.1016/j.jri.2022.103612}, journal-iso = {J REPROD IMMUNOL}, journal = {JOURNAL OF REPRODUCTIVE IMMUNOLOGY}, volume = {158}, unique-id = {34212243}, issn = {0165-0378}, keywords = {immunology}, year = {2023}, eissn = {1872-7603} } @article{MTMT:34212242, title = {[8h30-50] Foetal-maternal interactions in pregnancy}, url = {https://m2.mtmt.hu/api/publication/34212242}, author = {Szekeres, Júlia and Tanics, Timea Judith Csabai and Gorgey, Eva and Bognar, Zoltan and Mikó, Éva}, doi = {10.1016/j.jri.2022.103517}, journal-iso = {J REPROD IMMUNOL}, journal = {JOURNAL OF REPRODUCTIVE IMMUNOLOGY}, volume = {158}, unique-id = {34212242}, issn = {0165-0378}, keywords = {immunology}, year = {2023}, eissn = {1872-7603} } @article{MTMT:34212237, title = {[9h20-9h30] Immune checkpoint ligands expressed by embryo-derived extracellular vesicles}, url = {https://m2.mtmt.hu/api/publication/34212237}, author = {Gorgey, Eva and Tanics, Timea Judith Csabai and Bognar, Zoltan and Mikó, Éva and Szekeres, Júlia}, doi = {10.1016/j.jri.2022.103520}, journal-iso = {J REPROD IMMUNOL}, journal = {JOURNAL OF REPRODUCTIVE IMMUNOLOGY}, volume = {158}, unique-id = {34212237}, issn = {0165-0378}, keywords = {immunology}, year = {2023}, eissn = {1872-7603} } @article{MTMT:34124223, title = {Long-Term Effects of ART on the Health of the Offspring}, url = {https://m2.mtmt.hu/api/publication/34124223}, author = {Ahmadi, Hamid and Aghebati-Maleki, Leili and Rashidiani, Shima and Csabai-Tanics, Tímea Judith and Nnaemeka, Obodo B. and Szekeres, Júlia}, doi = {10.3390/ijms241713564}, journal-iso = {INT J MOL SCI}, journal = {INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, volume = {24}, unique-id = {34124223}, issn = {1661-6596}, abstract = {Assisted reproductive technologies (ART) significantly increase the chance of successful pregnancy and live birth in infertile couples.

In spite of its inarguable usefulness, concerns about the health consequences of ART-conceived babies have been raised. There are reports about the association of ART with birth defects and health complications, e.g., malignancies, high blood pressure, generalized vascular functional disorders, asthma and metabolic disorders in later life. It has been suggested that hormonal treatment of the mother, and the artificial environment during the manipulation of gametes and embryos may cause genomic and epigenetic alterations and subsequent complications in the health status of ART-conceived babies.

Mononuclear cells were separated from peripheral venous blood and the frequency of CD8⁺, CD4⁺, double positive (DP), and double negative (DN) NKT cell subpopulations was determined using multicolor flow cytometry. Following the characterization, the expression levels of different immune checkpoint receptors and ligands were also defined. Soluble CD226 levels were quantified by ELISA. Novel and significant differences were revealed among the ratios of the investigated NKT subsets and in the expression patterns of PD-1, LAG-3, TIGIT and CD226 receptors. Further differences were determined in the expression of CD112, PD-1, LAG-3 and CD226 MFI values between the early-onset preeclamptic and the healthy pregnant groups. Our results suggest that the investigated NKT subpopulations act differently in the altered immune condition characteristic of early-onset preeclampsia and indicate that the different subsets may contribute to the compensation or maintenance of Th1 predominance.}, year = {2023}, eissn = {1422-0067}, orcid-numbers = {Feik, Timoteus/0000-0002-7776-5226; Nagy, Dávid/0000-0001-7742-4459; Szereday, László/0000-0002-1208-2969} }
