Immuno-targeting the multifunctional CD38 using nanobody

CD38, as a cell surface antigen is highly expressed in several hematologic malignancies including multiple myeloma (MM) and has been proven to be a good target for immunotherapy of the disease. CD38 is also a signaling enzyme responsible for the metabolism of two novel calcium messenger molecules. To be able to target this multifunctional protein, we generated a series of nanobodies against CD3...

Cell-specific targeting by engineered M13 bacteriophage expressing VEGFR2 nanobody

Objective(s): Filamentous bacteriophage M13 was genetically engineered to specifically target mammalian cells for gene delivery purpose. Materials and Methods: A vascular endothelial growth factor receptor 2 (VEGFR2)-specific nanobody was genetically fused to the capsid gene III of M13 bacteriophage (pHEN4/3VGR19). A mammalian expression construct containing Cop-green fluorescent protein (Cop-G...

Targeting CD38 alleviates tumor-induced immunosuppression

Targeting CD38, a common blood cell membrane receptor highly expressed on many Band T-cell cancers, has achieved significant clinical activity with an acceptable safety profile in multiple myeloma (MM). Specifically, daratumumab (dara) was the first naked CD38 monoclonal antibody (mAb) approved for the treatment of relapsed and refractory MM (RRMM) in 2015. Importantly, it induces high response...

Immuno-targeting of pancreatic cancer stem cells

Pancreatic cancer is a highly aggressive and deadly disease harboring a distinct population of cancer stem cells (CSC) that is not affected by conventional therapies. A new therapeutic approach using the EpCAM/CD3-bispecific antibody MT110 is capable of activating and redirecting cytotoxic T cells to eliminate primary human pancreatic cancer stem cells, which resulted in long-term survival of p...
