Erythropoietin-producing hepatoma (Eph) receptors, comprising the largest family of receptor tyrosine kinases (RTKs), exert profound influence on diverse biological processes and pathological conditions such as cancer. Interacting with their corresponding ligands, erythropoietin-producing hepatoma receptor interacting proteins (Ephrins), Eph receptors regulate crucial events like embryonic development, tissue boundary formation, and tumor cell survival. In addition to their well-established roles in embryonic development and cancers, emerging evidence highlights the pivotal contribution of the Ephrin/Eph family to cardiovascular physiology and pathology. Studies have elucidated their involvement in cardiovascular development, atherosclerosis, postnatal angiogenesis, and, more recently, cardiac fibrosis and calcification, suggesting a promising avenue for therapeutic interventions in cardiovascular diseases. There remains a need for a comprehensive synthesis of their collective impact in the cardiovascular context. By exploring the intricate interactions between Eph receptors, ephrins, and cardiovascular system, this review aims to provide a holistic understanding of their roles and therapeutic potential in cardiovascular health and diseases.

Upon injury, fibroblasts in the surrounding tissue become activated, migrating into the wound in a controlled manner. Once they arrive, they contract the wound and remodel the stroma. While certain cell surface receptors promote fibroblast migration, others cause repulsion between fibroblasts upon contact, seemingly opposing their clustering within the wound bed.

EFNA4, a member of the Ephrin-A ligand family, may influence hepatocellular carcinoma cells through two distinct mechanisms: one reliant on specific Eph receptor binding and the other independent of receptor involvement. However, EFNA4's influence on HCC via non-Eph receptor pathways remains unclear. In this study, we aimed to investigate the role of EFNA4 in a receptor-independent environment.

The activity of the receptor tyrosine kinase EphA4 has been implicated in several pathologies including oncology (gastric and pancreatic cancers) and neurodegenerative diseases (amyotrophic lateral sclerosis and Alzheimer's disease). However, advances in validating EphA4 as a possible drug target have been limited by the lack of suitable pharmacological inhibitors. Recently, we reported on the design of potent EphA4 agonistic agents targeting its ligand binding domain (LBD).

Receptor tyrosine kinases (RTKs) regulate many cellular functions and are important targets in pharmaceutical development, particularly in cancer treatment. EGFR and EphA2 are two key RTKs that are associated with oncogenic phenotypes. Several studies have reported functional interplay between these receptors, but the mechanism of interaction is still unresolved.
