The past 15 years of allergic disease research have produced extraordinary
improvements in our understanding of the pathogenesis of airway allergic diseases
such as asthma. Whereas it was previously viewed as largely an immunoglobulin
E-mediated process, the gradual recognition that T cells, especially Type 2 T
helper (Th2) cells and Th17 cells, play a major role in asthma and related
afflictions has inspired clinical trials targeting cytokine-based inflammatory
pathways that show great promise. What has yet to be clarified about the
pathogenesis of allergic inflammatory disorders, however, are the fundamental
initiating factors, both exogenous and endogenous, that drive and sustain B- and
T-cell responses that underlie the expression of chronic disease. Here we review
how proteinases derived from diverse sources drive allergic responses. A central
discovery supporting the proteinase hypothesis of allergic disease
pathophysiology is the role played by airway fibrinogen, which in part appears to
serve as a sensor of unregulated proteinase activity and which, when cleaved,
both participates in a novel allergic signaling pathway through Toll-like
receptor 4 and forms fibrin clots that contribute to airway obstruction.
Unresolved at present is the ultimate source of airway allergenic proteinases.
From among many potential candidates, perhaps the most intriguing is the
possibility such enzymes derive from airway fungi. Together, these new findings
expand both our knowledge of allergic disease pathophysiology and options for
therapeutic intervention.
