Abstract: Method for producing Yarrowia lipolytica acid-resistant recombinant lipase utilizing a culture medium without any products of animal origin or non-characterized mixtures such as tryptone, peptone or lactoserum, in addition to its uses. Recombinant strain of Yarrow lipolytica producing an excessive amount of lipase Lip2 referred to as YL-LIP2-6C and filed with the Collection Nationale de Cultures de Microorganismes (C.N.C.M.) under number I 3542, on Dec. 15, 2005 and its uses.

Abstract: The present invention deals with a modified polypeptide comprising three contiguous segments N, L and C represented by the formula N-L-C and comprising: a N-helix region of gp41 (N), a C-helix region of gp41 (C), and a connecting loop comprising a synthetic linker (L) between the N and C-helices, the linker replacing amino acids 593-617 of gp41, the numbering scheme being based upon the prototypic isolate HIV-1 HxB2 Clade B strain, said polypeptide comprising the calveolin-1 neutralizing and 98.6 D epitopes, but not 2F5 and 4E10 epitopes, not the fusion peptide, the polypeptide having a minimal immunogenic cross-reactivity with human interleukin 2 (IL2).

Abstract: The disclosure relates to immunological compositions for vaccinating human beings against infection by the Human Immunodeficiency Virus (HIV).

Abstract: The present invention concerns a new method for the purification of Heparin Binding Hemagglutinin (HBHA) robust and reproducible at an industrial scale. The purification is made from HBHA-producing microorganisms extracted in presence of a detergent, a solvent or a chaotropic agent, followed by a first elution on ion exchange resins. In a preferred embodiment, the elution on ion exchange resins is followed by a second chromatography on mixed mode sorbents.

Abstract: The present invention deals with a modified polypeptide comprising three contiguous segments N, L and C represented by the formula N?L?C and comprising: a N-helix region of gp41 (N), a C-helix region of gp41 (C), and a connecting loop comprising a synthetic linker (L) between the N and C-helices, the linker replacing amino acids 593-617 of gp41, the numbering scheme being based upon the prototypic isolate HIV-1 HxB2 Clade B strain, said polypeptide comprising the calveolin-1 neutral izing and 98.6 D epitopes, but not 2F5 and 4E10 epitopes, not the fusion peptide, the polypeptide having a minimal immunogenic cross-reactivity with human interleukin 2 (IL2).

Abstract: The present invention concerns a modified polypeptide containing at least an immunodominant region and the connecting loop between N- and C-helices of gp41 ectodomain of HIV-1, wherein the connecting loop includes at least a linker fragment having: —a size convenient for keeping the native conformation of the interaction between N- and C-helices, and —an hydrophily sufficient to provide a soluble and stable trimeric form to said modified polypeptide.

Abstract: Modified recombinant protein derived from Streptococcus pneumoniae PBP2x, referred to as mini-PBP2x, consisting of a concatenation of the fragments corresponding, respectively, to the amino acids located between positions 74 to 90, 186 to 199, 218 to 228 and 257-750, with reference to the sequence of the PBP2x protein of the strain R6 (SWISSPROT P14677 or GENBANK 18266817), each one of said fragments being preceded by a peptide fragment of 1 to 7 amino acids, and uses of said mini-PBP2x protein for selecting and identifying antibiotics which are active on ?-lactam-resistant strains of S. pneumoniae.
