PURPOSE Respiratory papillomas, caused by human papillomaviruses types 6 and 11 (HPV6/11), are premalignant lesions with potential for malignant conversion. The cytokine and chemokine micromilieu of papillomas is T(H)2-like with a marked absence of IFN-γ expression. To illuminate why patients with recurrent respiratory papillomatosis (RRP) fail to effectively control their disease, we further i...
Cutaneous T-cell lymphoma (CTCL) is a heterogeneous group of neoplastic disorders characterized by clonally derived and skin-homing malignant T cells that express high level of chemokine receptor CCR4, which is associated with their skin-homing capacity. CCR4 is also highly expressed on T-regulatory cells (Tregs) that can migrate to several different types of chemotactic ligand CCL17- and CCL22...
Immunohistochemical analysis of FOXP3 in primary breast tumors showed that a high number of tumor-infiltrating regulatory T cells (Ti-Treg) within lymphoid infiltrates surrounding the tumor was predictive of relapse and death, in contrast to those present within the tumor bed. Ex vivo analysis showed that these tumor-infiltrating FOXP3(+) T cells are typical Treg based on their CD4(+)CD25(high)...
BACKGROUND Increased proinflammatory cytokines and chemokines might contribute to infiltration of inflammatory cells and remodeling in airways of asthma. Although these molecules may be associated with asthma, there is lack of systemic evidence showing which and how important these events are in the disease. We aimed to analyze the concentrations of these molecules in the airways and relationsh...
The activated T cell-attracting CC chemokine CCL22 is expressed by stimulated B cells and mature dendritic cells (DC). We have cloned and sequenced the complete mouse gene, including 4 kb of the 5'-flanking promoter region, and detected two distinct sites for initiation of transcription by 5'-RACE. Reporter gene assays indicate that the promoter reflects the specificity of the endogenous gene. ...
STCP-1 stimulated T cell chemoattractant protein-1 (STCP-1) (macrophage-derived chemokine; MDC), a recently described CC chemokine for chronically activated T lymphocytes, was found to act specifically on a subset of memory CD4 lymphocytes that displayed a Th2 cytokine profile. Also, STCP-1, thymus and activation regulated chemokine (TARC), eotaxin, and eotaxin-2 acted specifically on in vitro ...
