    Abstract: The present invention relates to tools and methods for the generation of antibodies which specifically bind chemokine receptors, such as CC or CXC chemokine receptors. Provided are isolated sulfated polypeptides and conjugates thereof, which can be used for example as antigens or for off target panning to facilitate the generation of anti-human, anti-cynomolgus, and/or anti-mouse chemokine receptor antibodies, e.g. for the generation of antibodies with fully human CDRs and/or other favorable properties for therapeutic use. The present invention furthermore relates to antibodies and conjugates thereof which can be obtained by applying the aforementioned tools and methods. Provided are antibodies specifically binding to human, cynomolgus and/or murine CCR8 with favorable properties for therapeutic use, such as cross-reactive antibodies, fully human antibodies, low internalizing (including non-internalizing) antibodies, and antibodies efficiently inducing ADCC and/or ADCP in Treg cells.

  • Patent number: 11371056
    Abstract: In the present invention, HPPD polypeptides and plants containing them showing a full tolerance against one or more HPPD inhibitor herbicides belonging to various chemical classes are described. A set of mutant HPPD polypeptides have been designed which have either no or only a significantly reduced affinity to HPPD inhibitor herbicides and, at the same time, the rate of dissociation of the HPPD inhibitors of the mutant HPPD polypeptide is increased to such an extent that the HPPD inhibitors no longer act as slow-binding or slow, tight-binding inhibitors but, instead of this, have become fully reversible inhibitors. In particular, isolated polynucleotides encoding mutant HPPD polypeptides conferring tolerance to HPPD inhibitor herbicides belonging to various chemical classes are provided. Additionally, amino acid sequences corresponding to the polynucleotides are encompassed.
