Epha4 ephrin
WebEphA4 is enriched on dendritic spines of pyramidal neurons in the adult mouse hippocampus, and ephrin-A3 is localized on astrocytic processes that envelop spines. Activation of EphA4 by ephrin-A3 was found to induce spine retraction, whereas inhibiting ephrin/EphA4 interactions distorted spine shape and organization in hippocampal slices. WebJul 14, 2005 · In the present study, we report the postnatal expression of ephrin-B3 in myelinating oligodendrocytes in the mouse spinal cord. We further demonstrate that postnatal EphA4-positive cortical neurons retain their sensitivity to the ephrin-B3 in myelin and that this ligand accounts for a fraction of the inhibitory activity in CNS myelin …

WebFeb 19, 2024 · To confirm EphA4 is important for KSHV fusion and infection, we generated EphA2 and EphA4 single- and double-knockout cells. We found that both EphA2 and EphA4 play a role in KSHV fusion and infection, since EphA2-EphA4 double-knockout cells had the greatest decrease in fusion activity and infection compared to single-knockout cells.
