Abstract: The invention relates to an immunogenic composition for sublingual, perlingual or oral administration, comprising at least an antigen and at least an adjuvant that is a bacterium selected from a Bifidobacterium and a lactic acid bacterium, and/or a combination of a corticosteroid with vitamin D3 or any metabolite or analog of the latter, in a pharmaceutically acceptable carrier that is suitable for sublingual, perlingual, or oral administration. Such compositions allow to elicit antigen-specific immune tolerance.

Abstract: The present invention relates to the use of at least one peptide comprising or consisting of a sequence selected from the group consisting of SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4 and SEQ ID NO: 5, for determining the presence of extracts from at least one grass species in a composition.

Abstract: A pollen harvesting machine having a motorized chassis on which there are mounted heads for harvesting pollen by suction, which heads are connected by a suction circuit to a separation cyclone, which is connected to a suction fan. The separation cyclone is associated with a pollen recovery hopper. Each head comprises an assembly of a suction hood which has a generally frustroconical portion, which widens between an upper opening which is connected to the remainder of the suction circuits of the machine, and a polygonal base.

Abstract: A pollen harvesting machine having a motorized chassis on which there are mounted heads for harvesting pollen by suction and which heads are connected by a suction circuit to a separation cyclone which is in turn connected to a suction fan. The cyclone is associated with a pollen recovery hopper which is constructed to be cooled to freeze the harvested pollen.

Abstract: The present invention relates to a method for preparing raw pollen which is suitable for being used for the preparation of allergen extracts. The method involves instantaneously freezing the pollen immediately after harvesting, optionally followed by drying the frozen pollen by sublimation.

Abstract: In the method for combining with liposomes heterogeneous substances contained in a mixture, in particular, allergenic substances such as allergens and/or allergenic extracts, contained in an allergenic preparation, by adsorption on the surface of, and/or incorporation in, liposomes which comprise cholesterol, a phospholipid and/or at least one ionic lipid which gives the liposome a positive or negative charge, the liposome or its constituents are combined with the mixture of heterogeneous substances, the pH of the entire combination being higher or lower than the isoelectric point ip of the substances contained in the mixture, depending on whether the ionic lipid is charged positively or negatively respectively.
