Myeloid cell HIF-1α regulates asthma airway resistance and eosinophil function
Hypoxia-inducible factor (HIF)-1α is a master regulator of inflammatory activities of myeloid cells, including neutrophils and macrophages. These studies examine the role of myeloid cell HIF-1α in regulating a...

The tumor necrosis factor family member LIGHT is a target for asthmatic airway remodeling
Chronic inflammation of the airways is associated with remodeling and fibrosis, leading to a progressive decline in lung function in people with severe asthma. Michael Croft and his colleagues report that in m...

Open AccessChronic OVA allergen challenged Siglec-F deficient mice have increased mucus, remodeling, and epithelial Siglec-F ligands which are up-regulated by IL-4 and IL-13
In this study we examined the role of Siglec-F, a receptor highly expressed on eosinophils, in contributing to mucus expression, airway remodeling, and Siglec-F ligand expression utilizing Siglec-F deficient m...

Open AccessChronic allergen challenge induces bronchial mast cell accumulation in BALB/c but not C57BL/6 mice and is independent of IL-9
As genetically engineered mutant mice deficient in single genes are usually generated on a C57BL/6 background, to study mast cell trafficking in mutant mice, we initially investigated whether mast cells accumu...

Systemic Administration of Immunostimulatory DNA Sequences Mediates Reversible Inhibition of Th2 Responses in a Mouse Model of Asthma
This study investigated whether immunostimulatory DNA sequences (ISS) induce a transient or sustained inhibition of Th2 responses to inhaled antigen. We sensitized mice with subcutaneous injections to develop ...

Modulation of asthmatic response by immunostimulatory DNA sequences
A variety of DNA-based methods of modulating the immune and/or inflammatory response in animal models of asthma have shown significant promise. Antisense strategies seek to inhibit expression of specific host ...
