Plexin 抑制因子

Plexin signaling plays a fundamental role in various biological processes, including neuronal development, immune responses, and the regulation of cell migration. Plexins act as receptors for semaphorins, a class of secreted or membrane-bound proteins, which are involved in guiding neuronal axons and vascular patterning. Upon binding with semaphorins, Plexin receptors undergo a conformational change that triggers intracellular signaling cascades. These cascades often involve the regulation of the cytoskeleton, impacting cell shape and movement. Moreover, Plexin signaling is crucial in angiogenesis and immune cell regulation, influencing tissue development and repair processes.

Targeting Plexin pathways for disruption or inhibition is of significant interest. Inhibiting Plexin-semaphorin interactions can modulate the signaling pathways, altering pathological processes like tumor growth or abnormal neuronal development. Small molecule inhibitors, antibodies, or peptides that either mimic or block the action of semaphorins can be used to disrupt Plexin signaling.
