There is evidence that the treatment of bacterial meningitis with antibiotics liberates harmful bacterial products in the subarachnoid space (SAS). This enhances meningeal inflammation and in particular the recruitment of leukocytes into the cerebrospinal fluid (CSF), which has been shown to be more
It is presumed that adjuvant therapy rather than new antibiotics will improve the prognosis of pneumococcal meningitis. We investigated the effect of fucoidin, a polysaccharide inhibiting leukocyte rolling, on inflammatory changes in experimental meningitis in rats. After induction of meningitis by
The polysaccharide fucoidin, a homopolymer of sulfated L-fucose, is known, by interfering with the function of L-selectin, to inhibit leukocyte rolling, which is an early and essential step in the process of leukocyte extravasation into inflamed sites. We tested the inhibitory effect of fucoidin on
BACKGROUND AND PURPOSE; Chronic joint inflammation and pain are the hallmarks of disease in patients with inflammatory arthritis, notably rheumatoid arthritis. The aim of the present study was to investigate the relative contribution of tumour necrosis factor (TNF)-α, interleukin (IL)-1β and
Inflammatory recruitment of leukocytes into the cerebrospinal fluid (CSF) during bacterial meningitis has been shown to contribute significantly to the neurological damage commonly associated with this serious disease. In this study we tested whether or not inhibition of leukocyte rolling, a
OBJECTIVE
IL-33 signals through ST2 receptors and induces adaptive and innate inflammation. IL-33/ST2 is involved in adaptive inflammation-induced pain. Here, we have investigated the contribution of IL-33/ST2-triggered mechanisms to carrageenin-induced innate inflammation.
METHODS
Carrageenin- and
The inflammatory response in bacterial meningitis is mediated by cytokines, such as tumor necrosis factor alpha (TNF-alpha) and interleukin-1 (IL-1), which are produced in the subarachnoid space by different cells, e.g., leukocytes, astrocytes, and microglia. The recruitment of leukocytes into the
In our previous study, we reported that lipopolysaccharide (LPS) activated microglia and accelerated cerebral ischemic injury in the rat brain through the overexpression of cytokines in microglia. In the present study, we investigated the effect of the intraperitoneal administration of fucoidin, a
1. Control of inflammatory pain can result from activation of opioid receptors on peripheral sensory nerves by opioid peptides secreted from leukocytes in response to stress (e.g. experimental swim stress or surgery). The extravasation of immunocytes to injured tissues involves rolling, adhesion and
Recent reports suggest increased incidence and severity of Clostridium difficile-associated diseases. These facts have raised the need for additional clarification of pathogenesis and for a search for new therapeutic strategies. This study evaluated the effects of the polysaccharide fucoidin, an
BACKGROUND
During the last decades, the use of light-emitting diode therapy (LEDT) has increased significantly for the treatment of wound healing, analgesia and inflammatory processes. Nevertheless, scientific data on the mechanisms responsible for the therapeutic effect of LEDT are still
OBJECTIVE
Oxidized ATP (oATP) is a selective inhibitor of the P2Z/P2X7 ATP receptor for extracellular ATP, which contributes to the antinociceptive effect. This study sought to determine the mechanism by which local administration of oATP is able to relieve inflammatory pain in arthritic rat
1. In order to accumulate at sites of inflammation, leukocytes initially roll on endothelial cells of postcapillary venules before becoming firmly attached. This process of rolling is mediated by selectins which bind to carbohydrate counter-ligands present on the surface of both leukocytes and
Neutrophil migration is responsible for tissue damage observed in inflammatory diseases. Neutrophils are also implicated in inflammatory nociception, but mechanisms of their participation have not been elucidated. In the present study, we addressed these mechanisms in the carrageenan-induced
Patients with inflammatory bowel disease are susceptible to microvascular thrombosis and thromboembolism. The increased incidence of thrombosis is accompanied by enhanced coagulation and abnormalities in platelet function. Clinical studies have revealed thrombocytosis, alterations in platelet
