EX VIVO NK CELL DIFFERENTIATION FROM CD34+ HEMATOPOIETIC CELLS
20210054338 · 2021-02-25 ·

The present invention relates to the ex vivo differentiation of NK cells from CD34+ hematopoietic stem cells. Such NK cells and their progenitor cells can be used in therapies of a broad range of malignancies. In the present invention it is shown that IL-12 modulates ex vivo NK cell differentiation. Specific, we achieved significantly higher expression of KIR, CD16 and CD62L in the presence of IL-12 in the cell culture system. The induction of receptor expression by IL-12 occurred predominantly on an augmented population of CD33+NKG2A+ NK cells early during NK cell differentiation. These cells further show enhanced cytolytic activity against MHC class I positive AML targets. In line with the enhanced CD16 expression, IL-12 modulated ex vivo generated NK cells exhibit an improved antibody-dependent-cytotoxicity, using anti CD20 antibody on various B cell targets. Additional to the enhanced expression of CD62L, we show that this cell population consists of a specific chemokine receptor profile. By showing an increased capacity for adhesion to lymphendothelial cells and a specific chemokine receptor profile, we show that IL-12 provided the ex vivo generated NK cells with specific tissue-homing abilities.

NEW SEQUENCE SPECIFIC REAGENTS TARGETING CCR5 IN PRIMARY HEMATOPOIETIC CELLS

The invention pertains to the field of cell therapy and HIV treatments. It provides with highly specific reagents for reducing or inactivating expression of CCR5 in primate and human primary cells, especially under the form of TALE-nucleases. These reagents allow the production of safer primary hematopoietic cells made resistant to HIV, stem cells or differentiated cells, for their infusion into HIV patients.

High throughput 3D assay for immune cell and drug homing, migration and tumor cytotoxicity
10859565 · 2020-12-08 · ·

The present disclosure relates to methods for performing assays for active migration and cytotoxicity of a therapeutic agent towards tumor cells, e.g., immune cell and/or drug homing, migration, and tumor cytotoxicity. The methods are performed in labware that provide opportunities for a therapeutic agent, such as an immune cell or a drug, to migrate toward tumor cells, including tumor cells growing in a 3D spheroid conformation. The methods allow for, among other uses, the investigation of the effects of a therapeutic agent, such as immune cells or a drug, on tumor cells, and enable the investigation of homing, tumor cytotoxicity, and tumor immune evasion in a single, easy-to-use, high throughput system for more in vivo-like testing.
