In an attempt to characterize genes participating in the allergic late phase reaction, we have isolated a novel intercrine/chemokine (called MARC) from a cDNA library of the stimulated mouse mast cell line, CPII. As measured by Northern blotting, it is strongly upregulated at the mRNA level after the physiological challenge of the cells with immunoglobulin (Ig)E plus antigen. Unstimulated cells completely lack significant, stable expression, as do a number of other, different cell lines (uninduced and induced) and mouse tissues. In contrast to the Northern blot analysis, a polymerase chain reaction (PCR) analysis, performed on CPII cells and on Percoll gradient purified mouse peritoneal mast cells, revealed a basal level of transcription in the uninduced stage. After 2 h of IgE plus antigen challenge, a quantitative reverse transcriptase-PCR, using a spiked in MIMIC, showed a level of transcripts more than 100-fold higher in the CPII cells and 5-20-fold higher in purified mouse peritoneal cavity mast cells. This rapid induction after the Fc epsilon RI challenge, the identification of the gene as a member of the chemokine family, and its upregulated expression in peritoneal mast cells, all suggest an involvement in certain acute and chronic pathological mast cell-driven diseases.

DEFINITION Asthma is a syndrome characterized by increased responsiveness of the trachea and bronchi to various stimuli and is manifested by widespread reversible narrowing of the airways that changes in severity either spontaneously or as a result of therapy.1 The hyperresponsiveness ("twitchiness") of airways is a fundamental abnormality and is dynamic in nature. Asthma is a disease of persistent or recurrent airway inflammation characterized by the presence of inflammatory cells (eosinophils and polymorphonuclear cells), edema of the wall, and changes in epithelial cells. Airway response to allergens and certain irritants may be acute (occurring within minutes to one hour following exposure), delayed or late (occurring within four to eight hours following exposure), or dual (combination of acute and late phase). Some reactions are only delayed. The late phase reaction is largely attributed to ongoing inflammation. Because of the variability of its presentation (complete v partial reversibility of airways obstruction, hyperreactivity accompanying other respiratory disease, chronic cough, or recurrent pneumonia with or without wheeze), children have often been denied appropriate antiasthmatic medications and their symptoms have been attributed instead to "wheezy bronchitis," "recurrent bronchiolitis," "spastic bronchitis," or "wheezy baby syndrome." For years pediatricians have been schooled to approach the wheezing child skeptically ("all that wheezes is not asthma").
