The goal of this study was to formulate technologies that allow for successful gene transduction in primary natural killer (NK) cells. The dextran-mediated lentiviral transduction of human or mouse primary NK cells results in higher gene expression efficiencies. This method of gene transduction will vastly improve NK cell genetic manipulation.

Lentiviruses are a valuable research tool for exploring gene function; however, researchers may wish to avoid production of pantropic lentivirus encoding known or suspected oncogenes. As an alternative, we present a safer protocol for use of ecotropic lentivirus on human cells modified to express the ecotropic receptor mSlc7a1.
FAQs
The process begins when an engineered viral vector binds compatible receptors on the primary cell surface. This interaction enables cellular entry and delivery of DNA or RNA into the cell. The delivered material can then alter or be used to study gene expression, making receptor engagement and intracellular delivery central determinants of whether the intended genetic change can occur.
Integrating vectors insert delivered genetic sequences into the host genome, which can support longer-lasting genetic modification. Nonintegrating systems do not insert the sequence into the genome and therefore support temporary expression. This distinction helps researchers match the transduction strategy to the experiment, depending on whether sustained modification or short-term gene expression is more informative.
A successful experiment must deliver genetic material while preserving enough healthy primary cells for meaningful analysis or downstream use. Transduction efficiency indicates how effectively cells receive the intended material, whereas viability reflects whether the cells remain alive and physiologically useful. Considering both outcomes prevents high delivery rates from being interpreted as success when cell health is compromised.
Primary cells retain more physiologically relevant behavior because they are freshly isolated and non-immortalized, but that advantage comes with greater sensitivity and difficulty during modification. Immortalized cells are not the focus of this approach. Consequently, primary cell transduction is valuable when biological relevance matters, while efficiency and preservation of cell health require particularly careful evaluation.
A general workflow starts with freshly isolated primary cells and an engineered vector carrying DNA or RNA of interest. The vector is allowed to interact with the cells so delivery can occur, after which researchers assess altered gene expression alongside cell viability. Comparing these outcomes shows whether the modification produced usable, physiologically relevant cells for the intended study.
Researchers apply the method to investigate gene function, model disease processes, produce modified immune or stem cells, and evaluate gene-based therapies. These uses connect genetic manipulation with cellular behavior in a biologically relevant setting. The resulting cells can help reveal how particular genetic changes influence a disease model or support development and assessment of therapeutic strategies.
