Neutrophil-activating peptide-1/interleukin 8, a novel cytokine that activates neutrophils.
TLDR
It has been shown that CSa, formylmethionyl peptides, PAF, and LTB4 act via unrelated receptors, suggesting that neutrophil recruitment can result from the concerted action of multiple stimuli.
Impaired monocyte migration and reduced type 1 (Th1) cytokine responses in C-C chemokine receptor 2 knockout mice.
TLDR
It is concluded that CCR2-/- mice have significant defects in both delayed-type hypersensitivity responses and production of Th1-type cytokines, suggesting an important and unexpected role for C CR2 activation in modulating the immune response, as well as in recruiting monocytes/macrophages to sites of inflammation.
The Functional Role of the ELR Motif in CXC Chemokine-mediated Angiogenesis (*)
TLDR
A functional role of the ELR motif is suggested in determining the angiogenic or angiostatic potential of CXC chemokines, supporting the hypothesis that the net biological balance between angiogenicity and angiOSTatic CXCs may play an important role in regulating overall angiogenesis.
Abnormalities in Monocyte Recruitment and Cytokine Expression in Monocyte Chemoattractant Protein 1–deficient Mice
TLDR
It is indicated that MCP-1 is uniquely essential for monocyte recruitment in several inflammatory models in vivo and influences expression of cytokines related to T helper responses.
Tumor necrosis factor alpha and interleukin 1 stimulate the human immunodeficiency virus enhancer by activation of the nuclear factor kappa B.
TLDR
It is demonstrated that two different peptide hormones, or cytokines, stimulate the human immunodeficiency virus enhancer, and this effect is mediated by nuclear factor (NF) kappa B (nuclear factor that binds the kappa immunoglobulin light chain gene enhancer); this link between binding at the surface membrane and stimulation of a specific transcription factor should help define intermediates for these cytokine activation pathways.
Interleukin-8 as a macrophage-derived mediator of angiogenesis.
TLDR
A function for macrophage-derived IL-8 in angiogenesis-dependent disorders such as rheumatoid arthritis, tumor growth, and wound repair is suggested.
Inflammatory cytokines in patients with persistence of the acute respiratory distress syndrome.
TLDR
IL-8 and ENA-78 were the cytokines most strongly and consistently correlated with PMN concentrations in the lung fluids of patients with ARDS, and the correlations were independent of the other cytokines or coexisting lung infection.
TLR3 is an endogenous sensor of tissue necrosis during acute inflammatory events
TLDR
Data show that TLR3 is a regulator of the amplification of immune response and serves an endogenous sensor of necrosis, independent of viral activation, and anti-TLR3 antibody attenuated the tissue injury associated with gut ischemia and significantly decreased sepsis-induced mortality.
An important role for the chemokine macrophage inflammatory protein-1 alpha in the pathogenesis of the T cell-mediated autoimmune disease, experimental autoimmune encephalomyelitis.
TLDR
It is demonstrated that MIP-1 alpha plays an important role in directing the chemoattraction of mononuclear inflammatory cells in the T cell-mediated autoimmune disease, EAE.
Cultured lung fibroblasts isolated from patients with idiopathic pulmonary fibrosis have a diminished capacity to synthesize prostaglandin E2 and to express cyclooxygenase-2.
TLDR
F-IPF have a striking defect in their capacity to synthesize the antiinflammatory and antifibrogenic molecule PGE2, apparently because of a diminished induction of COX-2 protein, which may contribute to the inflammatory and fibrogenic response in IPF.
