Previous studies suggested that the eosinophil recruitment into the site of cutaneous late-phase reaction (LPR) was dependent on IgE antibody and mast cells. In this study, we determined the role of CD4+ T cells and CD8+ T cells in causing antigen-induced eosinophil recruitment of LPR in mouse skin. Eosinophil infiltration into the subcutaneous tissue of(More)
In order to determine the role of CD4+ and CD8+ T-cells and of interleukin-5 (IL-5) in causing antigen-induced eosinophil infiltration into the site of airway late-phase reaction, we examined the effect of the in vivo depletion of CD4+ and CD8+ T-cells on the eosinophil infiltration of the trachea induced by antigen inhalation in mice. We also studied the(More)
In order to determine the role of CD4+ T cells and CD8+ T cells in causing antigen-induced eosinophil infiltration into the site of late-phase reaction (LPR), we examined the effect of the in vivo depletion of CD4+ T cells and CD8+ T cells on antigen-induced eosinophil infiltration into mouse skin.

Previous studies have shown that substance P induces granulocyte infiltration in mouse skin, which is mediated through mast cell degranulation. However, it is not yet known whether the direct effect of substance P on vascular endothelial cells is involved in the granulocyte infiltration in the skin. To solve this issue, we used the N-terminal peptide(More)
The growth and reproductive characteristics of dolphinfish Coryphaena hippurus collected in the waters off western Kyushu from May 2008 to April 2011 were determined based on scale and otolith readings and gonad histological examinations, respectively. Based on annual increments in scales and daily increments in sagittal otoliths, the von Bertalanffy growth(More)
It has recently been shown that substance P induces neutrophil infiltration in the skin, which is mediated through mast cell degranulation. Since substance P activates both skin mast cells and vascular endothelial cells, we compared the potencies of substance P and a mast cell-degranulating agent, compound 48/80, which is inactive for vascular endothelial(More)
Substance P causes granulocyte (neutrophil and eosinophil) infiltration in mouse skin by inducing mast cell degranulation. However, the mediator responsible for this granulocyte infiltration has not been determined. In this study, we examined the effect of a leukotriene B4 (LTB4) antagonist ONO-4057 on substance P-induced granulocyte infiltration in the(More)
To determine whether the N-terminal or C-terminal peptide of substance P (SP) induces granulocyte infiltration in mouse skin, we examined the potencies of SP, the N-terminal peptides SP1-4 and SP1-9, the C-terminal peptides SP4-11 and SP6-11, and a mast cell degranulating agent compound 48/80 in inducing granulocyte (neutrophil and eosinophil) infiltration(More)
In 1984, Gleich et al. originally reported a novel syndrome of episodic angioedema with eosinophilia. The syndrome is characterized by recurrent angioedema, urticaria, weight gain, elevated IgM levels, marked blood eosinophilia, and eosinophil infiltrates in the dermis. It has also been observed that activated CD4+ T cells are present in the dermis of(More)
