On Trk for Retrograde Signaling
Target-derived neurotrophins like nerve growth factor (NGF) mediate biological effects by binding to and activating Trk neurotrophin receptors at nerve terminals. The activated Trk receptors then stimulate local effects at nerve terminals, and retrograde effects at neuronal cell bodies that often reside at considerable distances from the terminals. However, the nature of the retrograde signal h...

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...

15 صفحه اولThe effect of P75 on Trk receptors in neuroblastomas.
Neuroblastomas (NBs) with favorable outcome usually express TrkA, whereas unfavorable NBs frequently express TrkB and its cognate ligand BDNF. P75 (p75(LNTR), NGFR, TNFRSF16) binds NGF-related neurotrophins with low affinity and usually is coexpressed with Trk receptors in NBs. Here, we investigated the importance of p75 coexpression with Trk receptors in NBs. We transfected p75 into two Trk-nu...
متن کاملStar Trk(B)
The generation and transmission of the information in the central nervous system (CNS) strongly rely on the structural and functional framework formed by neuronal cells. However, astrocytes, the major glial cell type, may profoundly impact on the performance of the framework, as they give metabolic and trophic support to neurons, and regulate synapse formation and function. Under pathological s...
