The invention describes a method and compounds for the prevention of immune responses towards allofactors, towards viral vectors used for gene therapy and gene vaccination, towards proteins to which subjects are naturally exposed, towards genetically-modified organisms and towards undesirable effects related to vaccine administration for allergic or infectious diseases.

A peptide comprised of either a binary or a tertiary peptide, the peptide contains at least 4 amino acids and up to a maximum of 16 amino acids, comprised of 2 or 3 different regions, wherein the binary peptides have 2 different regions and the tertiary peptides have 3 different regions; wherein, the peptide can be cleaved by both an animal gut protease and an insect or nematode gut protease.

A molecule or molecule complex capable of binding to TLR9 and to CD32 comprising at least one epitope of at least one antigen, its production and its use a medicament, especially for the treatment of allergies.

The present invention relates to a fusion protein comprising a first peptide and a second peptide linked together with a linker, wherein the first peptide is an allergen and the second peptide is a targeting unit and the targeting unit is a FGL-2 C-terminal peptide according to SEQ ID no 1. Provided herein are also uses of said fusion protein as a vaccine for treating allergy, such as shrimp, peanut or mite allergy, as well as a vaccine composition and methods for producing such fusion proteins.

The invention describes a method and compounds for the prevention of immune responses towards allofactors, towards viral vectors used for gene therapy and gene vaccination, towards proteins to which subjects are naturally exposed, towards genetically-modified organisms and towards undesirable effects related to vaccine administration for allergic or infectious diseases.

An immobilized polypeptide including a polypeptide bound to a surface of a polypeptide array or a chip, wherein the polypeptide has the amino acid sequence of SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:1 lacking the N-terminal methionine, SEQ ID NO:3 lacking the N-terminal methionine, or a combination thereof.

The invention describes a method and compounds for the prevention and treatment of infections with intracellular organisms, the treatment of tumors, and the prevention of infectious and allergic diseases by vaccination.

Provided are an optimized Der f2 gene, a recombinant Der f2 protein encoded thereby, a vector comprising said gene, and a Pichia pastoris strain. Also provided are an expression method, a purification method, and an application of the recombinant Der f2 protein.

The present invention discloses processes for producing native, depigmented and polymerised allergen extracts. The invention further discloses extracts produced via the processes, and pharmaceutical and vaccine compositions comprising the extracts, for diagnosis and treatment of allergy.

A molecule or molecule complex capable of binding to TLR9 and to CD32 comprising at least one epitope of at least one antigen, and its use a medicament for the treatment of allergies.
