  • New Research Seeks to Advance Understanding, Improve Treatments of Substance Abuse

    A press release last week from the National Institutes of Health announced the awarding of some $11 million over 3 years to support research exploring the use of social media to advance the scientific understanding, prevention, and treatment of substance use and addiction. The awards are funded through the Collaborative Research on Addiction at NIH (CRAN), an NIH consortium involving the National Institute on Alcohol Abuse and Alcoholism (NIAAA), the National Institute on Drug Abuse (NIDA), and the National Cancer Institute (NCI).

    The announcement notes the potential of interactive platforms such as Facebook and Twitter as tools to help scientists identify prevailing attitudes and myths and to gain insights into patterns of use, risk factors, and behaviors associated with substance use and misuse. By providing a platform for communicating science-based, health-related messages, social media may also enhance screening, prevention, and treatment of substance use and addiction.

  • Molecular Discovery May Advance Disease Prevention and Treatment
    New research published this week in the journal Immunity advances our understanding of the mechanisms underlying the onset of chronic inflammation. The discovery of 2 microRNA molecules that appear to control inflammation may also enable the development of more effective treatments for the subsequent ailments, such as cancer or autoimmune disorder that often occur, especially with aging. Previous studies have shown that chronic inflammation is linked to the development of certain conditions including diabetes, lupus, arthritis, obesity, cancer, neurodegeneration, and cardiovascular disease along with a shortened life span. Certain types of immune cells, called T follicular helper cells, are known to promote the production of antibodies that attack our own tissues and contribute to chronic inflammation. This study found that the microRNAs at issue are produced by and act to control these important cell types. Read more about the research here.

  • Findings May Illuminate New Targets for Therapeutic Intervention of Neuropathic Pain
    New research published online in the journal Neuron may offer leads to improved understanding of neuropathic pain. The authors identified a novel protein expressed specifically in nociceptors that acts as a key player in analgesic signaling through GABAB receptors. The protein, Gα inhibitory interacting protein (GINIP), could offer a new line of attack to boost GABA transmission by targeting peripheral neurons selectively, possibly avoiding side effects of system-wide GABAB activation. With neuropathic pain, the spinal cord suffers a loss of signaling by GABA, the nervous system’s main inhibitory transmitter. GABA receptors have thus seemed a likely target to dampen neuropathic hyperexcitability, but considerable efforts toward that aim have largely failed, mainly because GABA receptors are found throughout the nervous system. Because GINIP is restricted to nociceptors—the neurons relevant to neuropathic pain—targeting the GABAB-GINIP interaction may facilitate the development of a new therapeutic agent that specifically interferes with GABAB signaling related to pain.

  • World Congress on Pain Previews New Systemic Review of the Evidence
    A news article in Pain Research Forum covering proceedings at the 15th World Congress on Pain examines the clinical management of neuropathic pain, including a presentation on proposed new guidelines for the treatment of neuropathic pain. The paper additionally previewed a future where neuropathic pain patients will no longer be lumped together by etiology and treated for generic pain, but rather will be sorted by transetiological symptoms or signs and treated with rational therapies based on the underlying mechanisms of pain. Over the years, several clinical guidelines have been produced based on systematic reviews and meta-analyses of existing clinical trials for the various medications used in the treatment of neuropathic pain. These primarily include antidepressants, antiepileptics, some opioids, and topical preparations. The author contends that an update is now in order, as the most recent guidelines are 4 or more years old. Since then, there have been several large trials, new treatments, and advances in techniques for evaluating evidence. Read the complete article, with links to source materials, here.
