CAR-NK Vector Products

Natural Killer (NK) cells, innate immune effectors known for their innate cytotoxicity, have emerged as promising candidates for CAR-based immunotherapy. CAR-NK cells are genetically engineered to express chimeric antigen receptors, effectively weaponizing them against specific target antigens, including those found on cancer cells. This approach combines the inherent advantages of NK cells, such as rapid response and tumor-killing capabilities, with the precision of CAR technology.

At Creative Biolabs, we recognize the immense potential of CAR-NK vectors in the therapeutic landscape. Our extensive experience and expertise uniquely position us to provide comprehensive insights into CAR-NK therapy.

CAR Design for CAR-NK Cells

The key to the success of CAR-NK therapy lies in the precise design of Chimeric Antigen Receptors, which confer the desired specificity and potency to NK cells.

• Target Antigen Selection

Selecting the appropriate target antigen is paramount in CAR-NK design. It defines the specificity of the therapy. Our team at Creative Biolabs meticulously evaluates the target antigen's expression on tumor cells and normal tissues to minimize off-target effects. We employ cutting-edge bioinformatics tools to ensure the highest specificity and minimal toxicity.

• CAR Structure Optimization

The CAR structure plays a pivotal role in CAR-NK cell function. A typical CAR consists of an extracellular antigen-binding domain, a transmembrane domain, and intracellular signaling domains. Our experts excel in tailoring CAR designs to enhance NK cell activation, persistence, and tumor cell killing. We optimize CAR structures for costimulatory domains, signal transduction pathways, and cytokine secretion profiles.

• Safety Measures

Ensuring the safety of CAR-NK therapy is paramount. Creative Biolabs prioritizes the inclusion of safety switches and control mechanisms in CAR designs. These switches, such as suicide genes or antibody-based off-switches, provide an additional layer of control over CAR-NK cells, allowing for rapid intervention in case of adverse events.
