Neuroendocrine Immune Implications in Rheumatoid Arthritis and Polymyalgia Rheumatica: Past and Present Unresolved Issues and Optimising Glucocorticoid Treatment

Neuroendocrine Immune Implications in Rheumatoid Arthritis and Polymyalgia Rheumatica: Past and Present Unresolved Issues and Optimising Glucocorticoid Treatment

Editorial Introduction and background The dramatic effects of cortisone and pituitary adrenocortical hormone therapy on rheumatoid arthritis (RA) were discovered almost seven decades ago (1) and even longer for the significant disease amelioration during pregnancy as reported by Hench in 1938 (2). However, major questions persist about the underlying adrenocortical and hypothalamic pituitary axis (HPA) […]

Adiponectin Enhances Th17 Actions and RANKL Expression Promoting Arthritis Inflammation and Bone Erosion

Adiponectin Enhances Th17 Actions and RANKL Expression Promoting Arthritis Inflammation and Bone Erosion

A study published in the online Scientific Reports journal reveals a new maladaptive and pro-inflammatory effect of adiponectin – its ability to increase T helper (Th)17 immune responses and the expression of receptor activator of nuclear factor-κB ligand (RANKL) in an animal model of arthritis. Adiponectin, a protein secreted mostly by adipocytes (fat cells),  is […]

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 […]

Vagus Nerve Stimulation Ameliorates Disease Activity in a Rodent Model of Rheumatoid Arthritis

Vagus Nerve Stimulation Ameliorates Disease Activity in a Rodent Model of Rheumatoid Arthritis

A study published in PLoS ONE is perhaps the first to demonstrate that electrical neurostimulation of the vagus nerve reduces signs of inflammation and disease severity in the collagen-induced arthritis (CIA), a disease model of rheumatoid arthritis in rodents. Previous research indicates that cholinergic signaling along the vagus nerve is able to affect the production […]

Neuroendocrine Immunology of Rheumatic Diseases: A 10-Year Update

Neuroendocrine Immunology of Rheumatic Diseases: A 10-Year Update

In 2001, Drs. Rainer Straub and Maurizio Cutolo, established experts in the field of neuroendocrine immunology of autoimmune and rheumatic diseases, published a large overview on the role of diverse neural and hormonal factors in rheumatoid arthritis. In the last decade, Maurizio Cutolo, president of the European League against Rheumatism (EULAR) has also organized the […]

Stress and Rheumatic Diseases

Stress and Rheumatic Diseases

SHORT FEATURES and FACES ARTICLE In an editorial published in Arthritis Research & Therapy, Afton Hassett and Daniel Clauw, of University of Michigan Medical School, discuss some aspects of the complex interactions between psychological stress and the onset, expression and progression of rheumatic diseases. The authors mention that some studies in this research area are […]

Overview of the ”New Generation” Cytokines

Overview of the ”New Generation” Cytokines

In this review, published in Arthritis Research & Therapy Cem Gabay and Iain McInnes present the biology and relevant pathophysiology of several novel cytokines, with focus on their involvement in rheumatic diseases. This list includes the interleukin (IL)-1 superfamily (IL-18 and IL-33), the IL-12 superfamily (IL-27 and IL-35), the IL-2 superfamily (IL-15 and IL-21), and […]
