MYELOID NEOPLASIA High-affinity neurotrophin receptors and ligands promote leukemogenesis
Neurotrophins (NTs) and their receptors play a key role in neurogenesis and survival. The TRK (tropomyosin-related kinase) receptor protein tyrosine kinases (TRKA, TRKB, TRKC) are high-affinity NT receptors that are expressed in a variety of human tissues. Their role in normal and malignant hematopoiesis is poorly understood. In a prospective study involving 94 adult patients we demonstrate for...

متن کاملSpecific high-affinity receptors for neurotrophin-3 on sympathetic neurons.
When used at concentrations allowing interactions only with its high-affinity receptors, neurotrophin-3 (NT-3) promotes the survival of sensory neurons isolated from embryonic day 8 (E8) chicks, but not the survival of E11 sympathetic neurons. These sympathetic neurons (which can be rescued by the addition of NGF) display high-affinity receptors for NT-3 (Kd of 1.6 x 10(-11) M) that cannot be d...
متن کاملThe neurotrophin receptor p75 binds neurotrophin-3 on sympathetic neurons with high affinity and specificity.
High-affinity neurotrophin-3 (NT3) receptors have been identified on nerve growth factor (NGF)-dependent sympathetic neurons, but their occupancy by NT3 does not lead to neuronal survival. The molecular nature of these NT3 binding sites was investigated in this study. With freshly dissociated embryonic day 11 (E11) chick sympathetic neurons, cross-linking experiments revealed that the main rece...
متن کاملDiscovering high-affinity ligands for proteins.
Drug discovery is a difficult and time-consuming process that involves the identification of potent therapeutic | TECH VI EW I agents with good bioavailability, metabolic stability, and low toxicity. An important first step in this process is the identification of molecules that bind with high affinity and selectivity to the biological target. High-affinity ligands might be discovered by screen...
