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
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
The polysaccharide fucoidin is a selectin blocker that inhibits leukocyte recruitment into the cerebrospinal fluid (CSF) during experimental pneumococcal meningitis. In the present study, the effect of fucoidin treatment on the release of the proinflammatory cytokines tumor necrosis factor alpha
BACKGROUND
Tumour necrosis factor alpha (TNF-alpha) is involved in non-steroidal anti-inflammatory drug induced gastropathy. Nitric oxide (NO) is a mediator of gastrointestinal mucosal defence but, paradoxically, it also contributes to mucosal damage.
OBJECTIVE
We optimised the C57BL/6 mouse model
Increased leukocyte ratio induced by intraperitoneal injection of TNF-alpha was analyzed in undisturbed rat mesentery venules, a long-term experimental model. TNF-alpha induced a biphasic increase in PMNL ratio in the mesentery venules; in particular, there was a large increase in PMNL ratio 3 h
Leukocyte rolling and adhesion are generally observed in venules but rarely observed in arterioles. With the use of intravital microscopy, we found that a 4-h treatment with interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha) dose dependently induced leukocyte rolling and
GMP-140 is a 140-kDa granule membrane glycoprotein localized to the alpha-granules of platelets and the Weibel-Palade bodies of endothelial cells. Expression of GMP-140 on the activated cell surface has been shown to mediate the adhesion of thrombin-activated platelets to neutrophils and monocytes
In a previous study, we showed that anti-CD11b or anti-CD18 antibody markedly attenuated platelet-activating factor (PAF)-induced shock and intestinal necrosis in rats, whereas anti-P-selectin anti-body was ineffective. Here we used genetically altered mice to study the mechanism of PAF in mice. We
Leukocyte adhesion and diapedesis, critical steps in the inflammatory process, depend on the expression of integrin CD11b/CD18. In this study, we examined the preventive effect of monoclonal antibodies (MAb) against CD11b (1B6), CD11a, or CD18 (CL26) on platelet-activating factor (PAF)-induced bowel
1 This study examines the involvement of kinins in neutrophil migration into rat subcutaneous air pouches triggered by lipopolysaccharide (LPS), as well as the putative roles played by kinin B(1) and B(2) receptors, tumour necrosis factor alpha (TNF-alpha), interleukin-1 beta (IL-1beta) and
Monocytes and macrophages can distinguish between tumour cells and non-malignant cells of the same cell type. The surface structures mediating tumour cell recognition and tumour cell-induced cytokine production by monocytes or macrophages are still poorly characterized. The authors previously
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
