Background

Neurotrophin 4 (NT-4) is a neurotrophic factor which supports the survival and outgrowth of sensory neurons from embryonic chicken dorsal root ganglia, but has no significant effect on embryonic day 8 sympathetic ganglia1. It has a strong survival/proliferative action on NIH 3T3 cells expressing trkB but little activity on 3T3 cells expressing trkA. NT-4 was originally identified in Xenopus and viper, and was subsequently identified in rat and humans. Neurotrophin 4 is the least studied member of the neurotrophin family. Genetic knockout of NT4 does not result in loss of any DRG sensory neurons, although this factor does influence survival of spinal motor neurons. NT4 is expressed in muscle, and its expression is regulated by activity of innervating motor neurons, which increase its production, thereby providing trophic support to those innervating neurons. This provides an excellent example of bidirectional communication between the target and the afferent neurons, in which the activity of the innervating neurons and the release of trophic factor from the target influence each other to fine-tune the synaptic connections.

Beautiful shoe
Size: 7, Color: Smoke Grey
This shoe is fairly narrow, which works fine for my narrow feet. Comfortable. Light. Nice color will match with lots of colors. Fairly comfortable but the skinny part by the toe I see how this would give anyone with a medium side foot blisters. It’s fine on me.

Runs small
Size: 8.5, Color: Sandstorm
This shoe is super cute and comfy. I usually wear an 8 or an 8½. I ordered the 8½, but it was too small, so I had to send it back. I reordered a 9, and it fit perfectly.

Love love these
Size: 7, Color: Black
Totally love these. I found them to run a bit short. I ordered a 6 1/2 (my normal size) - had to return them for a 7. But I love them.
