Systems and methods are provided for transfecting immune competent cells with RNA at high efficiency and viability.

Described herein are methods of making recombinant cells using an in silico-generated pathway map of an endogenous pathway in a cell of interest to determine, in silico, a predicted effect of incorporating a recombinant nucleic acid into the endogenous pathway; and based on the predicted effect, incorporating the recombinant nucleic acid into the endogenous pathway in the cell of interest such that activation of the endogenous pathway regulates expression of the recombinant nucleic acid.

The present disclosure relates to recombinant production reporter cells comprising a logic gate such that an expressible sequence (e.g., a reporter gene) is expressed after the occurrence of triggering event related to a stage of production or an environmental condition of a biological production system. Nucleic acids, kits, and methods for making and using the recombinant production reporter cells are also disclosed herein.

Systems and methods are presented that provide for improved NK cell function. In preferred aspects, NK-92 cells express recombinant er/LSP-IL-15 to so render the NK-92 cells independent of exogenous cytokines and to provide extracellular immune stimulation.

Compositions and methods are presented in which selected polypeptide compounds bind to CTLA-4. Most typically, binding is mediated by selected VH and/or VL domains, and preferred compounds are prepared as scFv, IgG, or CAR.

Systems and methods are presented that allow for determination and prediction of payload toxicity in therapeutic viruses. Disclosed herein are methods of determining payload toxicity of an expressed polypeptide in a cell, comprising: generating or procuring a plurality of expression vectors, each containing a different recombinant nucleic acid sequence that encodes a corresponding recombinant polypeptide; expressing the recombinant nucleic acid sequence in a plurality of host cells while culturing the host cells; sequencing the plurality of expression vectors after culturing the host cells; and correlating at least portions of the recombinant nucleic acid sequence with a toxicity measure.

Systems and methods are presented that allow for determination and prediction of payload toxicity in therapeutic viruses. Contemplated methods of determining payload toxicity of an expressed polypeptide in a cell may comprise the steps of generating or procuring a plurality of expression vectors, each containing a different recombinant nucleic acid sequence that encodes a corresponding recombinant polypeptide; expressing the recombinant nucleic acid sequence in a plurality of host cells while culturing the host cells; sequencing the plurality of expression vectors after culturing the host cells; and correlating at least portions of the recombinant nucleic acid sequence with a toxicity measure.

The present disclosure relates to recombinant therapeutic cells comprising recombinant sensor proteins, such that a therapeutic molecule is expressed after the occurrence of two separate triggering events that are sensed by the sensor proteins. Nucleic acids, kits, and methods for making and using the recombinant therapeutic cells are also disclosed herein.

Systems and methods for predicting an immune response against a tumor in a patient having the tumor are provided. The relative mass or changes of mass of tumor cells or immune cell in the tumor can be ex vivo observed, and an immune status of the tumor can be determined based on the mass of tumor cells or immune cell. The immune status can provide a guidance to predict the immune response against the tumor in the patient.
