Extracellular vesicles from seminal plasma interact with T cells in vitro and drive their differentiation into regulatory T-cells.

Seminal plasma induces immune tolerance towards paternal allogenic antigens within the female reproductive tract and during foetal development. Recent evidence suggests a role for extracellular vesicles in seminal plasma (spEVs). We isolated spEVs from seminal plasma that was donated by vasectomized men, thereby excluding any contributions from the testis or epididymis.

E3 ligases RNF43 and ZNRF3 display differential specificity for endocytosis of Frizzled receptors.

The transmembrane E3 ligases RNF43 and ZNRF3 perform key tumour suppressor roles by inducing endocytosis of members of the Frizzled (FZD) family, the primary receptors for WNT. Loss-of-function mutations in and mediate FZD stabilisation and a WNT-hypersensitive growth state in various cancer types. Strikingly, and mutations are differentially distributed across cancer types, raising questions about their functional redundancy.

Intracellular localisation and extracellular release of Y RNA and Y RNA binding proteins.

Cells can communicate via the release and uptake of extracellular vesicles (EVs), which are nano-sized membrane vesicles that can transfer protein and RNA cargo between cells. EVs contain microRNAs and various other types of non-coding RNA, of which Y RNA is among the most abundant types. Studies on how RNAs and their binding proteins are sorted into EVs have mainly focused on comparing intracellular (cytoplasmic) levels of these RNAs to the extracellular levels in EVs.
