This month's theme: Eosinophil-mediated disease

About the cover

The cover image shows an eosinophilic microabscess located in the esophageal epithelium of a patient with eosinophilic esophagitis. Note the surrounding tissue damage. Several articles in this month's issue examine the important role of eosinophils. A good place to start would be the Editorial by Rothenberg (p 1321), which provides an overview of the latest concepts about eosinophils as summarized in this issue of the Journal.

In the Current Reviews article, Dagmar and Hans-Uwe Simon (p 1291) present a clinically relevant classification of eosinophilic disorders based on new understandings of the disease mechanism. The Molecular Mechanisms review by Rosenberg et al (p 1303) summarizes recent advances in understanding eosinophil development and accumulation in inflamed tissues. In a Current Perspectives review, Jacobsen et al (p 1313) propose that eosinophils are critical immunoregulatory cells with pleotropic capabilities that affect diverse immune responses. In an Update Review, Munitz and Levi-Schaffer (p 1382) review the biology and therapeutic significance of a new set of inhibitory receptors expressed by eosinophils. Finally, in the Images in Allergy and Immunology feature, Foley and colleagues (p 1563) review the role of eosinophils in diverse tissue remodeling responses. Overall, we are now in a very strong position to design ways to modulate the activity of eosinophils in a variety of immune responses, opening the door to new approaches for therapeutic intervention in allergic disease. Articles relevant to the theme of “Eosinophil-mediated disease” are noted in the Table of Contents by a red starburst next to their titles.

This month in Beyond Our Pages

Two reports deal with the beneficial effects of different pharmacotherapeutic agents in chronic obstructive pulmonary disease. • The effects of the blockade of TNF activity in asthma have been described. • A study has further defined the characteristics of memory TH2 lymphocytes. • Another study has explored the function of IL-31, a cytokine that is expressed by TH2 lymphocytes; its function has been unclear. • The role of IL-15 in breaking the homeostasis in the intestinal tract has been explored as a possible underlying mechanism in celiac disease. • Investigators have uncovered evidence that the etiology of idiopathic pulmonary fibrosis is related to abnormal chromosomal telomere formation.

Mechanisms of asthma and allergic inflammation 

Update review

Inhibitory receptors on eosinophils: A direct hit to a possible Achilles heel?1382

Ariel Munitz, PhD, and Francesca Levi-Schaffer, PhD, Jerusalem, Israel

Original articles

Mechanisms of tissue inhibitor of metalloproteinase 1 augmentation by IL-13 on TGF-β1–stimulated primary human fibroblasts1388

Xiuxia Zhou, PhD, Haizhen Hu, BS, Mai-Lan N. Huynh, MD, Chakradhar Kotaru, MD, Silvana Balzar, MD, John B. Trudeau, BA, and Sally E. Wenzel, MD, Pittsburgh, Pa, and Denver, Colo

IL-13 augments the profibrotic effect of TGF-β1 on tissue inhibitor of metalloproteinase 1 through complex interactions of extracellular regulated kinase and phosphoinositde-3 kinase–Akt pathways, which modulate Smad signaling. These interactions may help explain the profibrotic state associated with TH2 inflammation in asthma.

Connective tissue growth factor expression is regulated by histamine in lung fibroblasts: Potential role of histamine in airway remodeling1398

Steffen Kunzmann, MD, Carsten Schmidt-Weber, PhD, Jean-Marc Zingg, PhD, Angelo Azzi, PhD, Boris W. Kramer, MD, Kurt Blaser, PhD, Cezmi A. Akdis, PhD, and Christian P. Speer, MD, Würzburg, Germany, Davos and Bern, Switzerland, and Maastricht, The Netherlands

The mechanism of histamine-induced accumulation of connective tissue growth factor implies a new therapeutic option against airway remodeling in asthma by administration of histamine receptor 1 antagonist.

The IL-17F signaling pathway is involved in the induction of IFN-γ–inducible protein 10 in bronchial epithelial cells1408

Mio Kawaguchi, MD, Fumio Kokubu, MD, Shau-Ku Huang, PhD, Tetsuya Homma, MD, Miho Odaka, MD, Shin Watanabe, MD, Shintaro Suzuki, MD, Koushi Ieki, MD, Satoshi Matsukura, MD, Masatsugu Kurokawa, MD, and Mitsuru Adachi, MD, Tokyo and Yokohama, Japan, and Baltimore, Md

IL-17F induces IFN-γ–inducible protein 10 (IP-10) through activation of the Raf1–MEK1/2–ERK1/2–p90RSK–CREB pathway. The IL-17F–IP-10 axis might be especially important in the pathophysiologic events of airway inflammation.

Expression and regulation of intercellular adhesion molecule-1 on airway parasympathetic nerves1415

Zhenying Nie, PhD, Cole S. Nelson, PhD, David B. Jacoby, MD, and Allison D. Fryer, PhD, Portland, Ore

Expression of intercellular adhesion molecule-1 (ICAM-1) in parasympathetic nerves is induced by antigen challenge, TNF-α, and IFN-γ. Dexamethasone and nuclear factor κB inhibitors block ICAM-1 in nerves and might limit the neural inflammation caused by eosinophils that is characteristic of asthma.

Integrin β3 genotype influences asthma and allergy phenotypes in the first 6 years of life1423

Emma E. Thompson, PhD, Lin Pan, MS, Irina Ostrovnaya, PhD, Lauren A. Weiss, PhD, James E. Gern, MD, Robert F. Lemanske, Jr, MD, Dan L. Nicolae, PhD, and Carole Ober, PhD, Chicago, Ill, and Madison, Wis

This study replicates associations with integrin β3 single nucleotide polymorphisms and asthma and IgE, further implicating this gene early in pathogenesis. Integrin β3 appears to play an important role in asthma development and may represent a target for treatment.
