There is still an unresolved paradox with respect to the immunomodulating role of estrogens. On one side, we recognize inhibition of bone resorption and suppression of inflammation in several animal models of chronic inflammatory diseases. On the other hand, we realize the immunosupportive role of estrogens in trauma/sepsis and the proinflammatory effects(More)
Energy regulation (EnR) is most important for homoeostatic regulation of physiological processes. Neuroendocrine pathways are involved in EnR. We can separate factors that provide energy-rich fuels to stores [parasympathetic nervous system (PSNS), insulin, insulin-like growth factor-1, oestrogens, androgens and osteocalcin] and those that provide(More)
The skin and its major appendages are prominent target organs and potent sources of key players along the classical hypothalamic-pituitary axis, such as corticotropin releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and alpha melanocyte stimulating hormone (alpha-MSH), and even express key steroidogenic enzymes. Therefore, it may have(More)
We investigated chronic psycho-social stress effects on stress-related parameters and on pathohistological changes in the murine colon. Moreover, we aimed to reveal the involvement of adrenal glucocorticoids in chronic stress effects. Chronic subordinate colony housing (CSC, 19 d) resulted in reduced body weight gain, thymus atrophy, adrenal hypertrophy,(More)
OBJECTIVE In this study we describe clinical and immunogenetic findings in 62 unselected patients with relapsing polychondritis. METHODS In a multicenter study, clinical data of 26 (41.9%) female and 36 (58.1%) male patients were collected. HLA-DR specificities were identified in 60, and the frequencies were compared with those in healthy controls. (More)
Our objective was to investigate sympathetic and sensory nerve fibers in synovial tissue in rheumatoid arthritis (RA) and osteoarthritis (OA) in relation to histological inflammation and synovial cytokine and norepinephrine (NE) secretion. Immunohistochemistry was used to detect nerve fibers and inflammatory parameters. A superfusion technique of synovial(More)
Both cellular and humoral functions of the immune system are modulated by the sympathetic nervous system (SNS). This interaction is mainly mediated by the release of catecholamines (CA) and their receptor-specific action on immune cells. However, neuropeptide Y (NPY), also present in sympathetic nerve terminals, is released upon SNS-stimulation. NPY(More)
During the last 10 years, a series of exciting observations has led to a new theory of pathophysiology using insights from evolutionary biology and neuroendocrine immunology to understand the sequelae of chronic inflammatory disease. According to this theory, disease sequelae can be explained based on redirection of energy-rich fuels from storage organs to(More)
There has been a consistent gap in understanding how TNF-α neutralization affects the disease state of arthritis patients so rapidly, considering that joint inflammation in rheumatoid arthritis is a chronic condition with structural changes. We thus hypothesized that neutralization of TNF-α acts through the CNS before directly affecting joint inflammation.(More)
