Abstract:
A variant of a parent polypeptide including an Fc region, which variant exhibits increased binding to FcRn as compared to the parent polypeptide and includes at least one amino acid modification in the Fc region.
Abstract:
This invention relates to an expression cassette for expressing polypeptides in eukaryotic cells using alternative splicing. The expression cassette comprises in 5′ to 3′ downstream direction: a promoter; a sequence transcribed in a 5′ untranslated region (5′UTR); a donor splice site; an intron; a first acceptor splice site; a first cistron encoding a first polypeptide; a second acceptor splice site; a second cistron encoding a second polypeptide; an internal ribosome entry site (IRES) operably linked to a selection marker; and a sequence transcribed in a 3″ untranslated region (3′UTR) including a polyadenylation signal, wherein the polyadenylation signal is unique.
Abstract:
The present invention provides an in vitro method for obtaining a library of polynucleotides encoding antibodies, derivatives thereof or fragments thereof, comprising the step of performing random mutagenesis of a polynucleotide encoding the variable region of a heavy chain and/or the variable region of a light chain of a light chain, wherein random mutagenesis is performed on a library of polynucleotides comprising a sequence encoding the variable region of a heavy chain and/or the variable region of a light chain; and wherein the random mutagenesis process creates randomly distributed mutations along at least 70% of the sequence encoding the variable region.
Abstract:
A method for producing a variant of a parent polypeptide including a Fc region, which variant exhibits reduced binding to the protein C1q and to at least one receptor Fcgγ R as compared to the parent polypeptide.
Abstract:
A variant of a parent polypeptide including an Fc region, which variant exhibits increased binding to FcRn as compared to the parent polypeptide and includes at least one amino acid modification in the Fc region.
Abstract:
The present invention concerns a peptide of following formula I: R being a side chain having at least one heteroatom selected from sulfur, nitrogen and oxygen in a carbonyl form (C═O); R1 being either H or a lipophilic chain; R2 being either OH or a lipophilic chain. More particularly the present invention concerns a cosmetic composition comprising a peptide as recited above and a physiologically acceptable medium. Results on the activity of the compounds are obtained and on the general state of the skin and its appendages, in particular via the stimulation of extracellular matrix components.
Abstract:
According to the present invention the extract of plant origin of the Globularia genus is used for a non-therapeutic cosmetic treatment of the skin and/or appendages. Preferably the species is Globularia cordifolia and the extract is obtained by in vitro plant culture. The extract can be used in particular for preventing and/or treating skin ageing by stimulating the 10 reactions of detoxification and cellular regeneration through a hormetic type response, for improving the transparency and radiance of complexion, for preventing or treating sensitive and reactive skins, for preventing or treating rednesses, for preventing protein glycation, for increasing and/or maintaining the number of dermal stem cells, for increasing and/or maintaining the dermal macromolecules, in particular collagen and elastin, for increasing the volume of the dermis, for 15 preventing and/or treating fines lines and wrinkles, for firming skin, for preventing hair loss and/or stimulating hair regrowth. The invention also proposes an original method of obtaining the extract by in vitro plant culture of undifferenciated cells of Globularia and an extract of plant origin that can be obtained by such method.
Abstract:
The subject matter of the present invention is a cosmetic or dermopharmaceutic composition comprising a combination of homarine and erythritol as well as a non-therapeutic treatment method of the skin to improve cutaneous hydration, to prevent and/or treat cutaneous dryness signs, to restore and/or protect the cutaneous barrier function, to protect cells of the skin and/or of the scalp from osmotic shocks, for example from UV induced osmotic shocks.
