  • Patent number: 12351622
    Abstract: The present invention is directed to a variant of a parent polypeptide containing an Fc region of a dog or cat IgG, that shows a higher binding activity to a dog or cat neonatal Fc receptor (FcRn) than a binding activity of the parent polypeptide to a dog or cat FcRn, wherein the Fc region contains at least one amino acid modification. The variant shows an enhanced FcRn binding activity under acidic conditions. Using the variant, therefore, an antibody (IgG) and Fc fusion protein having longer retention in plasma can be provided.

  • Patent number: 12253528
    Abstract: The present invention relates to the allergy field. Several independent groups have recently investigated the implication of PCSK9 on inflammation and sepsis but none of them have determined 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 on 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.
