In particular, the invention relates to an in vitro diagnostic method of assessing the susceptibility of a subject to develop progressive COPD involving the appearance of irreversible lung damage, wherein the expression of the marker gene DMBT1 and optionally one or more further marker genes selected from KIAA1199, TMSB15A, DPP6, SLC51B, NUDT11, ELF5, AZGP1, PRRX1, AQP3, SFN, GPR110, GDF15, RASGRF2, RND1, PLA1A, FGG, CEACAM5, HYAL2, AHRR, CXCL3, CYP1A1, CYP1B1, CYP1A2, CST6, NTRK2, COMP, ITGA10, CTHRC1, TAL1, FIBIN, BEX5, BEX1, ESM1 and GHRL is determined. The invention also relates to an in vitro method of diagnosing stable COPD or assessing the susceptibility of a subject to develop stable COPD, wherein the expression of DMBT1 and optionally one or more further marker genes selected from KIAA1199, TMSB15A, DPP6, SLC51B, NUDT11, ELF5, AZGP1, PRRX1, AQP3, SFN, GPR110, GDF15, RASGRF2, RND1, PLA1A, FGG, CEACAM5, HYAL2, AHRR, CXCL3, CYP1A1, CYP1B1, CYP1A2, CST6, NTRK2, COMP, ITGA10, CTHRC1, TAL1, FIBIN, BEX5, BEX1, ESM1 and GHRL is determined. Furthermore, the invention relates to the use of primers for transcripts of the aforementioned marker genes, the use of nucleic acid probes to transcripts of these marker genes, the use of microarrays comprising nucleic acid probes to transcripts of these marker genes, and the use of antibodies against the proteins expressed from these marker genes in corresponding in vitro methods. In vitro methods of monitoring the progression of COPD are also provided, in which the expression of marker genes according to the invention is determined.

COLLAGEN TYPE VII ALPHA 1 ASSAY

A method of immunoassay for detecting in a biological sample a fragment of collagen type VII alpha 1 comprising an N- or C-terminal neo-epitope, the method comprising contacting the biological sample comprising the fragment of collagen type VII alpha 1 comprising the N- or C-terminal neo-epitope with an antibody of the invention, and determining the amount of binding of the antibody

METHODS AND COMPOSITIONS FOR TREATING ASTHMA AND ALLERGIC DISEASES

The present invention relates to allergy field. Several independent groups have recently investigated the implication of PCSK9 on inflammation and sepsis but none of them have determine its impact on allergies and/or asthma which is a global health burden. Inventors have obtained preliminary data on wild-type (PCSK9+/+) or PCSK9-deficient mice (PCSK9 −/−) and shown that, under basal condition and in the absence of a particular stimulus, PCSK9 deficiency significantly increases the percentage of regulatory T cells in the spleen, the mesenteric lymph nodes and Peyer's patches. Moreover, inventors have shown the effect of allergic challenge Non primary human bronchial epithelial cells on PCSK9 expression and secretion. Very interestingly, their first results obtained by Q-PCR showed that HDM and LPS increase PCSK9 mRNA levels. Accordingly, the present invention relates to inhibitors of PCSK9 for use in the treatment of asthma and/or allergic disease, such as food allergy.

METHOD FOR DETECTING BIOMARKERS
