Little is known about how nerve growth factor (NGF) signaling controls the regulated assembly of microtubules that underlies axon growth. Here we demonstrate that a tightly regulated and localized activation of phosphatidylinositol 3-kinase (PI3K) at the growth cone is essential for rapid axon growth induced by NGF. This spatially activated PI3K signaling is conveyed downstream through a locali...

Abstract Electrospun fibrous scaffolds capable of providing dual growth factor delivery in a controlled manner have distinctive advantages for tissue engineering. In this study, we investigated the formation, structure, and characteristics/properties bicomponent glial cell line-derived neurotrophic (GDNF) nerve (NGF) peripheral regeneration. GDNF NGF were incorporated into core-shell structured...

After nerve injury, adult sensory neurons can regenerate peripheral axons and reconnect with their target tissue. Initiation of outgrowth, as well as elongation of neurites over long distances, depends on the signaling of receptors for neurotrophic growth factors. Here, we investigated the importance of gp130, the signaling subunit of neuropoietic cytokine receptors in peripheral nerve regenera...

For many patients, pain is the first sign of cancer and, while pain can be present at any time, the frequency and intensity of pain tend to increase with advancing stages of the disease. Thus, between 75 and 90% of patients with metastatic or advanced-stage cancer will experience significant cancer-induced pain. One major unanswered question is why cancer pain increases and frequently becomes m...

Blockade of nerve growth factor (NGF) with antibodies is a promising strategy for treatment of chronic pain associated with osteoarthritis (OA). This narrative review describes the current status of NGF-blockade for the treatment of OA pain. We summarise briefly current evidence for the efficacy and risks of anti-NGF blockade. Two anti-NGF antibodies, tanuzemab and fasinumab, are in active deve...

Rat superior cervical ganglion neurons require the presence of nerve growth factor (NGF) to develop and survive in culture. If NGF is removed from the culture medium, then the neurons die of programmed cell death. We investigated the potential role of Ca2+ and reactive oxygen species in this process. We found that overexpression of human wild-type copper/zinc-superoxide dismutase in cultured su...

Background: Pivotal roles of Nerve growth factor (NGF) in the development and survival of both neuronal and non-neuronal cells indicate its potential for the treatment of neurodegenerative diseases. However, investigation of NGF deficits in different diseases requires the availability of properly folded human b-NGF. In previous studies bacterial expression of hNGF demonstrated the feasibility o...

BACKGROUND Safflower extract and aceglutamide (SA) has been used clinically for the treatment of cerebrovascular diseases such as cerebral embolism, hemorrhage, and mental deterioration. This study aimed to investigate the effect and mechanism of SA injection in the recovery of peripheral innervations of diabetic mice. METHODS The C57BL/6 male mice were divided into four groups: normal contro...
