Evidence for Small Fiber Neuropathy in the Cornea of Fibromyalgia Patients

Evidence for Small Fiber Neuropathy in the Cornea of Fibromyalgia Patients

A new study published in Seminars in Arthritis & Rheumatism indicates that in patients with fibromyalgia the density of small nerve fibers in the cornea is reduced, supporting an evolving concept that fibromyalgia is a small fiber neuropathy. Fibromyalgia is also considered a stress-related syndrome that affects predominantly women. Recent research suggests that fibromyalgia is […]

Cytokines Driving Sympathetic Nervous System Activation in the Subfornical Organ: Implications for Heart Failure and Hypertension

Cytokines Driving Sympathetic Nervous System Activation in the Subfornical Organ: Implications for Heart Failure and Hypertension

A recent study published in Hypertension demonstrates that cytokines such as interleukin (IL)-1β and tumor necrosis factor (TNF)-α acting at the level of the subfornical organ induce the expression of inflammatory and excitatory mediators that subsequently drive sympathetic nervous system activation. The subfornical organ (SFO), a highly vascularized structure is a circumventricular organ that lacks […]

Vitamin D Deficiency May Contribute to the Reduction of Sympathetic and Sensory Innervation in Arthritis

Vitamin D Deficiency May Contribute to the Reduction of Sympathetic and Sensory Innervation in Arthritis

A new study published in Neuroscience demonstrates that vitamin D deficiency in experimental animals is related to sensory and sympathetic denervation and reduced neurotrophin levels in the synovium. Several studies have associated vitamin D levels with rheumatoid arthritis (RA) development in humans. Thus, low vitamin D levels are documented in patients with active RA. Also […]

High Blood Interferon-γ Levels Linked to the Early Phase of Chronic Fatigue Syndrome

High Blood Interferon-γ Levels Linked to the Early Phase of Chronic Fatigue Syndrome

A study published in the February issue of the new journal Science Advances is perhaps the first to identify distinct stages of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Importantly, it demonstrates some immune signatures early in the course of ME/CFS that are not present in subjects with longer duration of illness. Although efforts were made to […]

Glucocorticoid Resistance of Th17 Cells in Takayasu Arteritis

Glucocorticoid Resistance of Th17 Cells in Takayasu Arteritis

A study published in the Arthritis & Rheumatology journal is perhaps the first to demonstrate that T helper (Th)1 and Th17 cells and cytokine pathways may play central role in driving systemic inflammation in Takayasu arteritis. Takayasu arteritis (TA) is a rare type of vasculitis that affects mostly middle-aged women, with greater frequency in Asia, […]

Therapeutic Potential of α7 Nicotinic Acetylcholine Receptor Agonists in a Murine Model of Rheumatoid Arthritis

Therapeutic Potential of α7 Nicotinic Acetylcholine Receptor Agonists in a Murine Model of Rheumatoid Arthritis

According to van Maanen et al., and their recent publication in PLoS One, two new experimental compounds affecting the acetylcholine-receptor system are able to delay collagen-induced arthritis (CIA) in mice, showing the therapeutic potential of chemicals targeting the α7 subunit of nicotinic acetylcholine receptors (α7nAChR). Previous research revealed that the efferent vagus nerve may decrease […]

Anxiety, Depression and Obesity May Jointly Contribute To Asthma Development

Anxiety, Depression and Obesity May Jointly Contribute To Asthma Development

A recent study by M. Brumpton et al., published in the International Journal of Epidemiology has shed light on the complex interactions and joint effects of anxiety, depression and obesity on the onset and development of asthma. Approximately 300 million people suffer from asthma, amounting to nearly 1% of the total global disease burden, worldwide. […]

Evidence that Napping May Correct Interleukin-6 Changes and the Stress Induction Caused By Sleep Deprivation

Evidence that Napping May Correct Interleukin-6 Changes and the Stress Induction Caused By Sleep Deprivation

A study published in the March issue of The Journal of Clinical Endocrinology & Metabolism (JCEM) indicates that short-term napping is able to restore, to a great extent, the neurohormonal and immune changes induced by sleep deprivation. Insufficient sleep is well-known to be associated with poor attention and performance deficits. However, an increasing body of […]

Blood Levels of the New Anti-Inflammatory Cytokine IL-37 Are Increased In Rheumatoid Arthritis Patients

Blood Levels of the New Anti-Inflammatory Cytokine IL-37 Are Increased In Rheumatoid Arthritis Patients

A recent study published in PLoS One suggests that interleukin (IL)-17 is involved in a control circuit that tries to regulate inflammation in rheumatoid arthritis. Rheumatoid arthritis (RA) is associated with increased levels of pro-inflammatory cytokines such as IL-6, IL-17A and tumor necrosis factor (TNF)-α. Early intervention and treatment of RA is based on disease-modifying […]

TRPV1 Sensory Nerves May Be Key to the Genesis of Airway Hyperreactivity in Experimental Asthma

TRPV1 Sensory Nerves May Be Key to the Genesis of Airway Hyperreactivity in Experimental Asthma

A new study in the Proceedings of the National Academy of Sciences (PNAS) of the USA implicates the transient receptor potential vanilloid 1 (TRPV1)-expressing sensory nerves in the pathogenesis of asthma and/or asthma attacks. The TRPV1 receptor, initially identified as the receptor for capsaicin, the hot component of chilli peppers, is typically expressed in sensory […]
