Overview of Gene Research
EphB4, a member of the Eph receptor family of receptor tyrosine kinases, plays crucial roles in multiple biological processes. It is involved in cell adhesion and migration, and its signaling pathways, such as EphrinB2-EphB4, are critical for cardiovascular formation, neuronal guidance during embryogenesis [1,2,3,6,7]. This signaling also intersects with the RAS-MAPK pathway, which is important in various cellular functions [4,5].
In animal models, LV-specific inducible EphB4-deficient mice and EphB4 knockin mice (EphB4 2YP) were used to study its role in lymphatic vessel (LV) valve development. Loss of EphB4 in LV blocked LV valve specification, continued valve development, and valve maintenance. In these models, defects in LV valve development were reversed by inhibiting the Ras-MAPK signaling pathway, indicating that EphB4-RASA1 interaction is necessary to limit Ras-MAPK activation in lymphatic endothelial cells [5].
In conclusion, EphB4 is essential for cardiovascular and neuronal development, as well as LV valve development. Mouse models, such as the EphB4-deficient and EphB4 knockin mice, have provided valuable insights into its role in these processes and the associated signaling pathways, contributing to our understanding of related physiological and pathological conditions.
