BACKGROUND Although the coexistence of bacterial meningitis and arthritis has been noted in several studies, it remains unclear how often both conditions occur simultaneously. METHODS We evaluated the presence of arthritis in a prospective nationwide cohort of 696 episodes of community-acquired bacterial meningitis, confirmed by culture of cerebrospinal fluid, which occurred in patients aged ...
Dark Agouti (DA) and Lewis rat strains were tested for susceptibility to collagen-induced arthritis (CIA) and for development of cellular and humoral immune responses to type II collagen (CII). All of the DA rats developed arthritis following a single intradermal injection of more than 20 microg of CII (130-150 microg/kg rat weight) and showed a swelling rate of more than 100% in the hind paws....
Destruction of bone and articular cartilage during pathogenesis of rheumatoid arthritis (RA) is caused by increased activity of a huge panel of proteases, which are secreted by several cell types of arthritic joint. Besides matrix metalloproteases (MMPs), the papain-like cysteine proteases (clan CA, family C1) have been identified as proteases potentially involved in car‐ tilage and bone destru...
Research describing fatty acids as modulators of inflammation and immune responses abounds. Many of these studies have focused on one particular group of fatty acids, omega-3. The data from animal studies have shown that these fatty acids can have powerful anti-inflammatory and immunomodulatory activities in a wide array of diseases (e.g., autoimmunity, arthritis, and infection). However, the e...
The Study Group for Risk Factors for Rheumatoid Arthritis was established by the EULAR Standing Committee on Investigative Rheumatology to facilitate research into the preclinical and earliest clinically apparent phases of rheumatoid arthritis (RA). This report describes the recommendation for terminology to be used to define specific subgroups during different phases of disease, and defines th...
Introduction: Immune system is involved in the etiology and pathophysiology of inflammation and vitamins are important sources of substances inducing nonspecific immunomodulatory effects. Given the proinflammatory role of cytokines in the inflammation and pain induction, this study aimed to assess the effects of long-term administration of vitamin B1 on the proinflammatory cytokines, edema, and...
T-cell responses to antigens are classified on the basis of the cytokines they produce as either Th1 (IFN-gamma, IL-2) or Th2 (IL-4, IL-10), with these Th types being indicative of either cell-mediated or antibody-mediated responses, respectively. Using this classification, T-cell responses in MHC-class-II-restricted autoimmune diseases appear to be predominantly of the Th1 type, based on the p...
Fc gamma receptors (Fc gammaRs) bind the constant Fc region of IgG molecules. IgG/antigen-containing immune complexes elicit a variety of effector functions in cells that express activating Fc gammaRs. Because activating Fc gammaRs are present on cells from the innate immune system, such as dendritic cells, monocytes/macrophages and granulocytes, these IgG receptors form a crucial link between ...
To maintain organismal homeostasis, phagocytes engulf dead cells, which are recognized as dead by virtue of a characteristic "eat me" signal exposed on their surface. The dead cells are then transferred to lysosomes, where their cellular components are degraded for reuse. Inefficient engulfment of dead cells activates the immune system, causing disease such as systemic lupus erythematosus, and ...
Prolactin (PRL) is a hormone synthesized and secreted by lactotroph cells in the anterior pituitary gland. There is also extrapituitary hormone secretion by many cells, including cells of the immune system. In physiological conditions PRL is responsible for lactogenesis and other processes associated with it. PRL plays a significant role during the immune response as a cytokine, affecting proli...
