IL - 2 Together with IL - 4 Adhesion Only if Induced to Express CCR 3 Eotaxin Activates T Cells

A novel human CC chemokine, eotaxin-3, which is expressed in IL-4-stimulated vascular endothelial cells, exhibits potent activity toward eosinophils.

IL-4 has been shown to be involved in the accumulation of leukocytes, especially eosinophils, at sites of inflammation by acting on vascular endothelial cells. To identify novel molecules involved in the IL-4-dependent eosinophil extravasation, cDNA prepared from HUVEC stimulated with IL-4 was subjected to differential display analysis, which revealed a novel CC chemokine designated as eotaxin-...

A549 cells can express interleukin-16 and stimulate eosinophil chemotaxis.

Alveolar epithelial cells produce many types of chemokines such as regulated on activation, normal T cells expressed and secreted (RANTES), eotaxin induced by interleukin (IL)-1 beta, or tumor necrosis factor (TNF)-alpha and may contribute to allergic disease by recruiting eosinophils. However, identification of the eosinophil chemotacic activity (ECA) release from A549 cells, an alveolar type ...

Multiplex determination of murine seminal fluid cytokine profiles.

Seminal fluid is known to be responsible for orchestrating mating-induced immunomodulation. Central to this process are numerous cytokines that modulate uterine leukocyte recruitment and trafficking. Despite this, a comprehensive analysis of the cytokine profile of murine seminal fluid is lacking. This study addressed this issue by using multiplex immunoassays to characterise the profile of int...

Selectively increased expression and functions of chemokine receptor CCR9 on CD4+ T cells from patients with T-cell lineage acute lymphocytic leukemia.

In a total of 38 typical T-cell lineage acute lymphocytic leukemia (T-ALL) and T-cell lineage chronic lymphocytic leukemia (T-CLL) cases investigated, we found that CC chemokine receptor CCR9 was selectively and frequently expressed on T-ALL CD4+ T cells, was moderately expressed on T-CLL CD4+ T cells, and was rarely expressed on normal CD4+ T cells. These findings were demonstrated at protein ...
