schwann cell apoptosis and p75ntr sirna
the p75 pan-neurotrophin receptor (p75ntr) plays a pivotal role in linking the immune system with the nervous system. p75ntr is required for the development of several characteristic features of allergic asthma. also p75ntr upregulated by reactive schwann cells after peripheral nerve injury. moreover p75ntr and rhoa play a critical role in the regulation of apoptosis. to determine whether the d...
متن کاملSchwann cell p75NTR prevents spontaneous sensory reinnervation of the adult spinal cord.
Schwann cells are attractive candidates for repair of the injured spinal cord. Transplanted Schwann cells are permissive to regeneration, but their ability to promote regeneration into distal spinal cord remains weak despite their production of growth-promoting neurotrophins. Schwann cell activation such as that which accompanies peripheral nerve injury results in massive upregulation of the p7...
متن کاملGlucose homeostasis and p75NTR
The p75 neurotrophin receptor (p75), a member of the tumor necrosis factor receptor (TNFR) superfamily, was originally identified as a receptor for neurotrophins and is expressed in the nervous system and in many non-neuronal tissues such as white adipose tissue (WAT), skeletal muscle and liver. Although the biological functions of p75 in the nervous system have been extensively studied, the mu...
متن کاملThe p75NTR intracellular domain generated by neurotrophin-induced receptor cleavage potentiates Trk signaling.
The p75 neurotrophin receptor (p75NTR) potentiates Trk signaling, but the underlying mechanisms remain uncertain. Here, we examine the relationship between p75NTR cleavage and Trk signaling. We found that, in PC12 cells, nerve growth factor (NGF) induces rapid and robust alpha-secretase- and gamma-secretase-dependent cleavage of p75NTR, releasing the resulting intracellular domain into the cyto...
متن کاملTherapeutic potential of cell therapy in the repair of hair cells and spiral ganglion neurons: review article
The mammalian cochlea is a highly complex structure which contains several cells, including sensory receptor or hair cells. The main function of the cochlear hair cells is to convert the mechanical vibrations of the sound into electrical signals, then these signals travel to the brain along the auditory nerve. Auditory hair cells in some amphibians, reptiles, fish, and birds can regenerate or r...
