Tropomyosin-receptor-kinases signaling in the nervous system

The development and function of the nervous system is dependent on many growth factors and their signaling. Tropomyosin-receptor-kinase receptor family controls synaptic strength and plasticity in the mammalian nervous system. Dysregulation of Tropomyosin-receptor-kinase receptors signaling can lead to neural developmental disorders and has been reported in certain diseases of the nervous system. Apart from their role in the nervous system, these tyrosine kinase receptors are also involved in cancer biology. Tropomyosin-receptor-kinases and their ligands, neurotrophins, are also involved in neural precursor stem cells differentiation. This review focuses on Tropomyosin-receptor-kinases, the most abundant receptors in mammalian nervous system.
