TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Dermatophagoides pteronyssinus is a trigger of atopic dermatitis. Many D pteronyssinus allergens are proteases that can elicit airway inflammation by stimulating the release of cytokines and chemokines by bronchial epithelial cells.', 'We sought to investigate whether D pteronyssinus allergens can exert a similar activity on skin keratinocytes.', 'Primary cultures of keratinocytes from healthy subjects or patients with atopic dermatitis and normal human bronchial epithelial cells were compared for cytokine production in response to D pteronyssinus extract.', 'Keratinocytes, but not bronchial epithelial cells, displayed a modest dose-dependent release of IL-1alpha and IL-1 receptor antagonist but no induction of their mRNA after exposure to D pteronyssinus. However, D pteronyssinus also degraded these cytokines. On the other hand, D pteronyssinus extract induced bronchial epithelial cells, but not keratinocytes, to increased expression of IL-8/CXCL8 and GM-CSF mRNA and protein. These effects were efficiently abrogated by a mixture of cysteine and serine protease inhibitors. Both IL-8 and GM-CSF were fully resistant to D pteronyssinus proteolytic attack. No induction of monocyte chemoattractant protein 1/CCL2, RANTES/CCL5, or IFN-gamma-induced protein of 10 kd/CXCL10 was detected in either cell type. Only bronchial epithelial cells expressed protease-activated receptor (PAR) 4 mRNA, whereas PAR-1, PAR-2, and PAR-3 mRNA was found in both cell types. D pteronyssinus did not affect PAR mRNA signals.'] Does house dust mite allergen exert no direct proinflammatory effects on human keratinocytes?
