CLEC9A and hydrops fetalis: We have described that HF stimulation, through a still-unknown component, probably F-actin or another protein related to necrotic cells, described in proteomic analysis of HF (Zeghir-Bouteldja et al., 2017; Schulz et al., 2018; Canton et al., 2021; dos Santos et al., 2022), induces downregulation of CLEC9A and CD205 in the cell membrane of BMDCs and this effect was not reversed with the use of EDTA.
