- Evaluation of the Ca37 Monoclonal Antibody Targeting Alcohol Dehydrogenase Against () In Vitro and In Vivo. Rodriguez-Erenaga, Oier Areitio, Maialen Abio-Dorronsoro, Lucia Cazalis-Bereicua, Nahia Aparicio-Fernandez, Leire Martin-Souto, Leire Buldain, Idoia Zaldibar, Beñat Rementeria, Aitor Antoran, Aitziber Ramirez-Garcia, Andoni () is an emerging pathogenic yeast of global concern due to its persistence on abiotic and biotic surfaces and the difficulty of treating the severe infections it causes, which are frequently associated with high mortality rates because of its extensive antifungal resistance. Thus, new therapeutic strategies are urgently needed to complement or replace current antifungal drugs. In this study, we evaluated the efficacy of Ca37, a monoclonal antibody (mAb) targeting the alcohol dehydrogenase (Adh) protein of , against both in vitro and in vivo. Protein electrophoresis and Western Blot analyses demonstrated immunoreactivity of Ca37 mAb with total protein and cell wall-associated protein extracts, among which Adh was identified. In vitro, incubation with Ca37 mAb significantly reduced the growth of several strains and enhanced the phagocytic activity of RAW 264.7 murine macrophages. In vivo, Ca37 mAb treatment increased the survival of larvae. In a murine model of systemic infection, treated mice displayed improved clinical condition, along with a greater number and larger area of immune-associated foci in the kidneys, suggesting enhanced fungal recognition. These findings support the potential of Ca37 mAb as an antifungal immunotherapy, although further studies in murine models are necessary to establish optimal dosing, efficacy, and mechanisms of action.
