Publication number: 20230049655Abstract: The present disclosure generally relates to therapies involving immune effector cells such as T cells engineered to express antigen receptors such as T cell receptors (TCRs) or chimeric antigen receptors (CARs). It is demonstrated herein that such antigen receptor-engineered immune effector cells may be generated in vitro/ex vivo as well as in vitro by delivering nucleic acid encoding an antigen receptor for genetic modification to cells using particles comprising the nucleic acid and a targeting molecule for targeting the immune effector cells, wherein the targeting molecule is a designed ankyrin repeat protein (DARPin). In particular, DARPins are described herein which are high-affinity binders for CDS binding to the CDS receptor on human and non-human primate (NHP) cells. Nanoparticles functionalized with CD8? targeting DARPins (CDS-DARPin) can deliver genes exclusively and specifically to human CD8+ T cells in vitro and in vivo.Type: ApplicationFiled: December 22, 2020Publication date: February 16, 2023Inventors: Annika FRANK, Jessica HARTMANN, Christian BUCHHOLZ, Benjamin RENGSTL, Arne Marten BILLMEIER, Ugur SAHIN, Hans-Ulrich SCHMOLDT, Philipp HELLER, Bonny Gaby LUI, Anne SCHLEGEL

Publication number: 20220064674Abstract: The present invention provides a composition comprising i) a pseudotyped retroviral vector particle comprising a) one envelope protein with antigen-binding activity, wherein said envelope protein is a recombinant protein that does not interact with at least one of its original receptors and is fused at its ectodomain to a polypeptide comprising an antigen binding domain specific for CD62L, and wherein said envelope protein is protein G, HN or H derived from the Paramyxoviridae family, b) one envelope protein with fusion activity derived from the Paramyxoviridae family, and T cells expressing CD62L. Alternatively, when said polypeptide comprising an antigen binding domain is specific for a tag of a tagged polypeptide instead of the antigen binding domain specific for CD62L, wherein said tagged polypeptide binds specifically to CD62L, then the composition comprises further said tagged polypeptide.Type: ApplicationFiled: September 2, 2021Publication date: March 3, 2022Inventors: Thomas SCHASER, Andrew KAISER, Laura KAPITZA, Jessica HARTMANN, Frederic THALHEIMER, Christian BUCHHOLZ

Patent number: 10415057Abstract: The invention relates to the pseudotyping of retroviral vectors with heterologous envelope proteins derived from the Paramyxoviridae family, genus Morbillivirus, and various uses of the resulting vector particles. The present invention is based on the unexpected and surprising finding that the incorporation of morbillivirus F and H proteins having truncated cytoplasmic tails into lentiviral vector particles, and the complex interaction of these two proteins during cellular fusion, allows for a superior and more effective transduction of cells. Moreover, these pseudotyped vector particles allow the targeted gene transfer into a given cell type of interest by modifying a mutated and truncated H protein with a single-chain antibody or ligand directed against a cell surface marker of the target cell.Type: GrantFiled: December 22, 2017Date of Patent: September 17, 2019Assignee: BUNDERSREPUBLIK DEUTSCHLAND, LETZVERTRETEN DURCH DEN PRÄSIDENTEN DES PAUL-EHRLICH-INSTITUTSInventors: Christian Buchholz, Sabrina Kneissl, Klaus Cichutek, Roberto Cattaneo

Patent number: 9901179Abstract: A piece of seating furniture having at least one base body, at least one adjustable functional part, at least one pivot fitting for adjusting the functional part relative to the base body and a separate, lift setting mechanism for locking the functional part in relation to the base body. The lift setting mechanism has a guide and a slender bar which can be moved in relation to the guide. The lift setting mechanism can be moved from a set position, blocking the adjustment of the functional part, to a reset position, unblocking the adjustment of the functional part. The pivoted lever is pivotably connected to the base body separately via two adjusting levers, the two adjusting levers are jointly connected to the base body via a control lever and one adjusting lever is pivotably connected to the base body via a guide lever.Type: GrantFiled: December 7, 2015Date of Patent: February 27, 2018Assignee: Ferdinand Lusch GmbH & Co.
