Maternal smoking induces significant changes in the morphological, rheological, and functional parameters of both maternal and foetal RBCs, mainly due to the continuous generation of the free radicals. The major aim of this study was to follow the consequences of a secondary stressor, like fungal infection, on the already compromised RBC populations. The impact of Candida infection, a growing health concern, was investigated on four blood sample groups: mothers and their neonates originating from non-smoking versus smoking populations. Here, we searched for phenotypical and molecular markers that precisely reflected the effect of Candida infection on the RBC membrane; this included the level of hemolysis, appearance of morphological variants, formation of the lipid peroxidation marker 4-hydroxyl-nonenal, arrangement of the Band 3 molecules and activation of the Caspase 3. In most of the examined cases, the fungal infection increased the adverse symptoms induced by smoking, indicating a general stress response, likely due to an altered redox state of the cells. However, we were able to identify an atypical phenotype (clustered populations with shrinkage and membrane blebbing) in both the non-smoking and smoking populations, which might be a unique marker for Candida spp. infection.<\/jats:p>","DOI":"10.3390\/ijms26010333","type":"journal-article","created":{"date-parts":[[2025,1,2]],"date-time":"2025-01-02T07:44:53Z","timestamp":1735803893000},"page":"333","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The Effect of a Secondary Stressor on the Morphology and Membrane Structure of an Already Challenged Maternal and Foetal Red Blood Cell Population"],"prefix":"10.3390","volume":"26","author":[{"given":"\u00c1gnes","family":"Ferencz","sequence":"first","affiliation":[{"name":"Department of Biochemistry and Molecular Biology, Faculty of Science and Informatics, University of Szeged, H-6701 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5471-2888","authenticated-orcid":false,"given":"Payal","family":"Chakraborty","sequence":"additional","affiliation":[{"name":"Department of Biochemistry and Molecular Biology, Faculty of Science and Informatics, University of Szeged, H-6701 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4450-0667","authenticated-orcid":false,"given":"Csaba","family":"Papp","sequence":"additional","affiliation":[{"name":"HCEMM-USZ Fungal Pathogens Research Group, Department of Biotechnology and Microbiology, Faculty of Science and Informatics, University of Szeged, H-6701 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andr\u00e1s","family":"Teleki","sequence":"additional","affiliation":[{"name":"Department of Biochemistry and Molecular Biology, Faculty of Science and Informatics, University of Szeged, H-6701 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Krisztina","family":"Dugmonits","sequence":"additional","affiliation":[{"name":"Department of Biochemistry and Molecular Biology, Faculty of Science and Informatics, University of Szeged, H-6701 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hajnalka","family":"Orvos","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynaecology, Albert Szent-Gyorgyi Medical School, University of Szeged, H-6701 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2939-9580","authenticated-orcid":false,"given":"Attila","family":"G\u00e1cser","sequence":"additional","affiliation":[{"name":"HCEMM-USZ Fungal Pathogens Research Group, Department of Biotechnology and Microbiology, Faculty of Science and Informatics, University of Szeged, H-6701 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0543-6693","authenticated-orcid":false,"given":"Edit","family":"Hermesz","sequence":"additional","affiliation":[{"name":"Department of Biochemistry and Molecular Biology, Faculty of Science and Informatics, University of Szeged, H-6701 Szeged, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Feltes, B.C., de Faria Poloni, J., Notari, D.L., and Bonatto, D.
