Galectin-1, the prototype of a family of beta-galactoside-binding proteins, has been implicated in a wide variety of biological processes. Data presented herein show that galectin-1 stimulates monocyte migration in a dose-dependent manner but is not chemotactic for macrophages. Galectin-1-induced monocyte chemotaxis is blocked by lactose and inhibited by an anti-galectin-1 antibody but not by n...
Neutrophil (polymorphonuclear leukocyte [PMN]) sequestration is one of the histologic hallmarks of an acute inflammatory response. During the natural evolution of an inflammatory response, PMNs are often replaced by mononuclear cells. This shift in the elicitation of specific leukocyte populations usually occurs as the inflammatory lesion enters either the repair/resolution stage or progresses ...
Leukemia inhibitory factor (LIF) is a cytokine released at the site of injuries where there is a recruitment of monocytes and polymorphonuclear cells. We analyzed the effect of LIF on human monocytes, which are a major source of chemotactic factors. We showed that supernatants of monocytes treated with LIF (50 ng/mL) for 18 hours had chemotactic activity for neutrophils and monocytes that was n...

The chemotactic responsiveness of the neutrophils of 10 patients with the hyperimmunoglobulin E-recurrent infection syndrome (HIE) were compared with neutrophils from normal volunteers over a 10-mo period. HIE neutrophils as a group displayed significantly less chemotactic motility than control neutrophils. The data from individual patients were variable, being normal or abnormal on different d...
Neurological transmitters including ACh, substance P (SP), and calcitonin gene-related peptide (CGRP) play an important role in regulating airway tone, and increased bronchial reactivity to cholinergic stimulation is a well-recognized phenomenon in patients with bronchial asthma. We postulated that ACh, SP, and CGRP might stimulate alveolar macrophages (AMs) to release neutrophil, monocyte, and...
OBJECTIVES Ureteral obstruction results in an injury response that can progress to irreversible renal fibrosis and tubular atrophy by apoptosis. The molecular events leading to apoptosis from obstruction are not well understood. We investigated the effect of bioflavonoids and angiotensin II inhibition on apoptotic and inflammatory gene expression in a model of unilateral ureteral obstruction (U...
The attraction, binding, and entry of monocytes into the vessel wall play an important role in atherogenesis. We have previously shown that minimally oxidized/modified LDL (MM-LDL), a pathogenically relevant lipoprotein, can activate human aortic endothelial cells (HAECs) to produce monocyte chemotactic activators. In the present study, we demonstrate that MM-LDL and oxidation products of 1-pal...
Mice lacking macrophage elastase (matrix metalloproteinase-12, or MMP-12) were previously shown to be protected from the development of cigarette smoke-induced emphysema and from the accumulation of lung macrophages normally induced by chronic exposure to cigarette smoke. To determine the basis for macrophage accumulation in experimental emphysema, we now show that bronchoalveolar lavage fluid ...
Leukotriene B4 (LTB4) is a potent chemotactic agent that activates monocytes through the LTB4 receptor (BLTR). We tested the hypothesis that LTB4 receptor blockade would slow atherosclerotic progression by inhibiting monocyte recruitment. Homozygous low-density receptor knockout (LDLr(-/-)) mice and apolipoprotein E deficient (apoE(-/-)) mice were treated with a specific LTB4 receptor antagonis...
