The NK-92MI, a fast-growing cytolytic cell line with a track record of exerting clinical efficacy, is transformed into a vector for synthesizing calibrated amounts of desired engineered proteins at our disease site, that is, NK-cell Biofactory. This provides an allogeneic option to the previously published T-cell-based living vector that is limited by high manufacturing cost and product variability. The modularity of this pathway, which combines a "target" receptor with an "effector" function, enables reprogramming of the NK-cell Biofactory to target diseases with specific molecular biomarkers, such as cancer, viral infections, or auto-immune disorders, and overcome barriers that may affect the advancement of NK-cell therapies.

Introduction: Glioblastoma (GBM) remains a deadly cancer with non-curative upfront treatment of radiation, resection, and chemotherapy. Not only has the standard of care for GBM patients not improved significantly over the past decade, life expectancy is less than 18 months, with no standard second-line therapy. We previously developed a 2 generation 4-1BB co-stimulated chimeric antigen receptor (CAR) targeting tumor-specific variant of the epidermal growth factor receptor (EGFRvIII) for treating patients with GBM.

Interleukin-15 (IL-15) exerts powerful stimulatory effects on lymphocyte subsets that result in antiviral and antitumoral activities. The functions of this cytokine are mainly mediated in a cell-to-cell contact fashion termed IL-15 trans-presentation. This function is mediated by a cell which tethers IL-15 to its plasmatic membrane complexed to IL-15 receptor alpha (IL-15Rα).

Yeast is an important host for the production of pharmaceutical or industrial proteins by virtue of its genetic information and easy handling. A number of heterologous proteins have been produced and purified from yeast cell cultures as secreted forms. Here, we describe a novel screening system of Saccharomyces cerevisiae and its application to improve the secretion efficiency of yeast.
