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...

Neurotrophins constitute a group of growth factor that exerts important functions in the nervous system vertebrates. They act through two classes transmembrane receptors: tyrosine-kinase receptors and p75 neurotrophin receptor (p75NTR). The activation p75NTR can favor cell survival or apoptosis depending on diverse factors. Several studies evidenced link between pathogenesis prion diseases. In ...

The p75 neurotrophin receptor (p75NTR) regulates neuronal survival, apoptosis, and growth. Recent studies have reported that disruption of Exon IV produces a null mouse lacking all p75NTR gene products (p75NTR ExonIV / ), whereas mice lacking p75NTR Exon III (p75NTR ExonIII / ) maintain expression of an alternatively spliced form of p75NTR (s-p75NTR). Here, we report that p75NTR ExonIV / mice e...

PURPOSE Apoptosis is the final common pathway for photoreceptors in several forms of retinitis pigmentosa. Recent study has shown that continuous light exposure upregulates low-affinity neurotrophin receptor p75 (p75NTR), which is involved in light-induced photoreceptor apoptosis in rat retina. However, the function of p75NTR in inherited forms of photoreceptor degeneration has not yet been exa...

The present study detected p75 neurotrophin receptor (p75NTR) expression in tongue squamous cell carcinoma (TSCC) cell lines, in order to define the biological properties of p75NTR+ cells and to confirm the use of p75NTR+ as a surface marker for TSCC stem cells. p75NTR+ cells were separated from Tca‑8113 and CAL‑27 TSCC cells by fluorescence‑activated cell sorting. Colony formation, MTT and scr...

UNLABELLED In this study, we investigated the clinicopathologic significance of the low-affinity p75 neurotrophin receptor (p75NTR; which is expressed in the stem/progenitor cell fraction of normal esophageal epithelial cells) in 187 resected esophageal squamous cell carcinoma (ESCC) specimens and found that approximately 50% of ESCC expressed p75NTR. Our investigation using ESCC cell lines sho...
