The protease allergen Der p 1 cleaves cell surface DC-SIGN and DC-SIGNR: Experimental analysis of in silico substrate identification and implications in allergic responses (2007)
Journal Article

Background: The cysteine protease Der p 1 from the house dust mite Dermatophagoides pteronyssinus is one of the most potent allergens known. An attractive mechanism for a component of Der p 1 allergenicity lies in its ability to cleave key regulatory...

Superior T cell activation by ESAT-6 as compared with the ESAT-6-CFP-10 complex (2005)
Journal Article

Using intracellular cytokine staining we show herein that T cells will respond to short-term (6 h) activation with phorbol ester plus ionomycin by production of tumor necrosis factor (TNF), IFN-γ or both. Here CD4 T cells preferentially produce TNF a... Read More about Superior T cell activation by ESAT-6 as compared with the ESAT-6-CFP-10 complex.

Activity profile of dust mite allergen extract using substrate libraries and functional proteomic microarrays (2004)
Journal Article

Enzymatic activity in the fecal droppings from the house dust mite has been postulated to contribute to the elicited allergic response. Screening dust mite extracts through 137,180 tetrapeptide fluorogenic substrates allowed for the characterization...

The proteolytic activity of the major dust mite allergen Der p 1 conditions dendritic cells to produce less interleukin-12: Allergen-induced Th2 bias determined at the dendritic cell level (2002)
Journal Article

Background: The proteolytic activity of the house dust mite allergen Der p 1 has recently been shown to bias Th cell subset development in favour of Th2. Apart from its direct effect on T cells, it is conceivable that the proteolytic activity of Der...

Human T cells that have been conditioned by the proteolytic activity of the major dust mite allergen Der p 1 trigger enhanced immunoglobulin E synthesis by B cells (2002)
Journal Article

Background: We have previously demonstrated that the proteolytic activity of Der p 1 selectively cleaves human CD25, the 55 kDa α subunit of the IL-2 receptor. As a result of cleavage of surface CD25, peripheral blood T cells produce less IFN-γ and m...

Human T cell subset commitment determined by the intrinsic property of antigen: The proteolytic activity of the major mite allergen Der p 1 conditions T cells to produce more IL-4 and less IFN-γ (2001)
Journal Article

The house dust mite Dermatophagoides pteronyssinus allergen Der p 1 elicits IgE antibody responses in a significant proportion of patients suffering from dust mite allergy. We have recently shown that Der p 1 proteolytically cleaves a cell surface mo...
