PIEZO2 Ion Channel Critical Mediator of Urinary Tract Function
New research has uncovered the mechanisms by which bladder stretch is sensed and the urethral reflexes involved in urination are controlled. The findings pinpoint the gene PIEZO2 as a key mechanosensor for interoception, which is the sensory regulation and awareness of what’s happening inside our bodies.

Study Explores Relationship Between Pain and Cognitive Impairment
A recent study exploring the association between pain and cognitive impairment (CI) found that pain and CI each increase the severity of the other; that is, when pain progresses from acute pain to high impact chronic pain (HICP), the severity of CI increases, and as the severity of CI increases, the severity of pain increases. Further, the study found that people with comorbid chronic pain and CI are in a much higher state of self-reported disability than people with either alone. The study, published in a recent issue of The Clinical Journal of Pain, was supported by the National Center for Complementary and Integrative Health (NCCIH), a component of the National Institutes of Health (NIH).

Characterizing Post-Exertional Malaise in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome
New research suggests that post-exertional malaise (PEM) in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) varies greatly among individuals and leads to a diminished quality of life. Recently published in the journal Frontiers in Neurology, this is the first publication resulting from the NIH Intramural Study on ME/CFS, which is led by the National Institute of Neurological Disorders and Stroke in collaboration with dozens of investigators from at least eight institutes and centers of the National Institutes of Health, including the National Center for Complementary and Integrative Health.

New Study Links Signaling by Immune Cells in the Meninges to Anxiety-Like Behavior
A new study provides insights into how a population of immune cells in the meninges (the membranes that cover the brain and spinal cord) regulates anxiety-like behavior in mice through neuroimmune signaling.

Comparing the Neural Effects of Placebo Pain Relief in Fibromyalgia Patients and Healthy Individuals

Although fibromyalgia is associated with changes in brain function and neural pathways, researchers saw no differences in responses to placebo pain relief between fibromyalgia patients and healthy volunteers in a new study. This research, funded by the National Center for Complementary and Integrative Health (NCCIH), was recently published in the journal Pain.

Researchers Develop New Metrics for Measuring Mental States During Meditation
In a recent proof-of-principle study, researchers developed a new framework, based on functional magnetic resonance imaging (fMRI) data, to identify mental states during meditation, including the focus-on-breath state and mind wandering, and to estimate how much time meditators spend in each state.

Study Provides New Insights Into Changes in Brain Function in Fibromyalgia

Pain at the time of testing, rather than the presence of a chronic pain condition, is primarily responsible for changes in the functioning of the brain’s default mode network in patients with fibromyalgia, according to the results of a study recently published in the journal NeuroImage. The study, conducted at the National Institutes of Health and McGill University, was partly funded by the National Center for Complementary and Integrative Health’s intramural research program.

New Study Provides Insight Into the Causation of Inflammatory Bowel Diseases
The abnormal production of a gut enzyme, lysozyme, which breaks down bacterial cell walls, affecting gut bacterial growth, may contribute to the causation of inflammatory bowel diseases by changing the composition of the gut bacterial community and thereby modifying mucosal inflammation, according to a new study published in the journal Immunity.

Sympathetic Nervous System Influences Development and Tissue Maintenance, Mouse Research Suggests
New animal research funded in part by the National Center for Complementary and Integrative Health (NCCIH), a component of the National Institutes of Health (NIH), suggests that stress-induced hair graying in mice may be an accessible model to investigate how stress influences tissue regeneration.
