1,25-Dihydroxyvitamin D3 Transcriptional Repression of Interleukin-17A Expression and Th17-Related Autoimmunity

1,25-Dihydroxyvitamin D3 Transcriptional Repression of Interleukin-17A Expression and Th17-Related Autoimmunity

In a new Molecular and Cellular Biology study, Sneha Joshi and colleagues from the University of Medicine and Dentistry of New Jersey, Newark demonstrate that the reversal of paralysis in EAE mice by 1,25-Dihydroxyvitamin D3 correlates with reduced IL-17A-secreting CD4+ T cells, and that the mechanism involved in 1,25-Dihydroxyvitamin D3-mediated suppression of IL-17A induction involves […]

Evolutionary Medicine, Energy Regulation and the Pathogenesis of Systemic Chronic Inflammatory Diseases

Evolutionary Medicine, Energy Regulation and the Pathogenesis of Systemic Chronic Inflammatory Diseases

Evolving Concepts The general meaning of the systemic response in inflammatory diseases is not well understood. Nor do we know whether the systemic response has any unfavorable role when inflammatory diseases become chronic. We call chronic inflammatory diseases (CIDs) “systemic in nature”, but the significance of these systemic signs and symptoms is not known. In […]

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 […]

PACAP as an Intrinsic Regulator of Treg Abundance

PACAP as an Intrinsic Regulator of Treg Abundance

A study published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS) provides perhaps the first evidence that endogenous pituitary adenylyl cyclase-activating polypeptide (PACAP) modulates the production or expansion of regulatory T cells (Treg) and T helper (Th)17 lymphocytes. PACAP is a 38-amino-acid neuropeptide identified in 1989 from […]
