Moderate-to-high levels of EphA4, EphA5, or EphA7 have been associated with longer survival in NSCLC patients.

Among the B class of Eph/ephrins, EphB3, EphB4, ephrin-B1, and ephrin-B3 have been investigated in lung carcinoma.

To better understand the functional role of EphA5 in the adult human central nervous system (CNS), we performed an immunohistochemical mapping study.

The abundance of stained neurons appeared to increase from.

The formation of complex neuronal circuitry requires precise spatial, temporal and cell-type-specific regulation of the responses of neurons to extracellular guidance and synaptogenic cues.

However, Robo receptors are essential for RGC axon guidance (Plump et al., 2002; Thompson et al., 2009), and since we do not find defects in RGC innervation of the SC in Kir2.1-expressing RGC axons until they navigate to the correct TZ, it is unlikely that this is the case. An alternative explanation for this apparent neural type-specific.

Eph receptors constitute the largest family of receptor tyrosine kinases, which are activated by ephrin ligands that either are anchored to the membrane or contain a transmembrane domain. These molecules play important roles in the development of multicellular organisms, and the physiological functions of these receptor-ligand pairs have been extensively documented in axon guidance, neuronal.

Furthermore, many studies analyzed the involvement of Eph. to increased frequency of axon guidance errors in this model [25]. to be overexpressed in squamous cell carcinoma of oral tongue and, therefore, implicated in malignancy [96]. Hence, among other investigated molecules, EphA5 receptor.

Neural progenitor cell proliferation, neuroblast migration, neuron survival, and neuronal plasticity also depend on Eph-ephrin interactions. The activation of EphB1, EphB2, EphB3, and EphA4 by ephrin ligands leads to migration of neuroblasts in the subventricular zone of the lateral ventricles in the adult mammalian brain [120].Ephrin-A5 is required for the survival of newborn neurons in adult.

Axon guidance by gradients plays an important role in wiring up the developing nervous system. Growth cones seem to sense a concentration difference across their spatial extent, and convert this into a signal to move up or down a gradient. In this article, a simple mathematical framework is developed to understand when and where gradient detection can occur as a function of gradient shape.
