Molecular nature of ‘sleeping’ pain neurons becomes clearer

Scientists have discovered the molecular characteristics of human sleeping nociceptors, which are key culprits in neuropathic pain. The findings provide a new framework for understanding the emergence of neuropathic pain at the molecular level and offer potential targets for developing targeted therapies.

New research offers hope for diabetic neuropathy sufferers

Nageotte nodules, previously largely ignored in research, are abundant in sensory ganglia of individuals with diabetic neuropathy and composed mainly of satellite glia and non-myelinating Schwann cells. These clusters may represent a target for drugs that protect nerves or help manage diabetic neuropathy.

Ultrasound device for pain gets ‘nod’ from Shark Tank and NIH funding

Researchers at Florida Atlantic University's Schmidt College of Medicine have developed a handheld ultrasound device to treat neuropathic pain. The device uses low-intensity focused ultrasound to target specific areas of the nervous system, offering a non-invasive and non-opioid-based treatment option.

Celestron NexStar 8SE Computerized Telescope

Celestron NexStar 8SE Computerized Telescope combines portable Schmidt-Cassegrain optics with GoTo pointing for outreach nights and field campaigns.

Stem cells may help replace lost sensory neurons

Researchers discovered stem cells in mouse dorsal root ganglia (DRG) with the potential to regenerate lost sensory neurons and glia. These cells, known as satellite glia, can become activated and generate new glia and, to a lesser extent, neurons after injury.

Multi-tasking protein at the root of neuropathic pain

A study published in Journal of Neuroscience reveals that FLRT3 protein, involved in neuron development and cell adhesion, is also critical for pain sensitization. High levels of FLRT3 protein were found in the dorsal horn following nerve injury, leading to touch sensitivity and mechanical allodynia.

Rigol DP832 Triple-Output Bench Power Supply powers sensors, microcontrollers, and test circuits with programmable rails and stable outputs.

Molecular markers used for assessment of early sciatic nerve injury

A study published in Neural Regeneration Research found that substance P and calcitonin gene-related peptide expression increased significantly in dorsal root ganglia after sciatic nerve injury, peaking at 7 days post-injury. This increase suggests these neuropeptides may serve as an index for evaluating early peripheral nerve injury.

Up a little on the left ... now, over to the right ...

Researchers identified a family of proteins called Mrgprs that functions as itch receptors in a rare subset of nerve cells. The study found that MrgprA3 is the primary itch receptor for chloroquine, leading to potential new treatments for nonallergic itch.
