NK Cell Therapy Development Services for Cancer

Alfa Cytology is committed to providing cutting-edge and comprehensive services for NK cell therapy development. Our services are designed to advance the preclinical development of NK cell therapies, support the discovery of NK cell therapy candidates, and provide promising avenues for cancer therapy.

Introduction to NK Cell Therapy

NK cell therapy, or natural killer cell therapy, has been used as an immunotherapeutic strategy to treat hematologic malignancies and solid tumors. NK cells are part of what makes up the immune system, and these specialized cells distinguish between healthy and abnormal cells (including tumor cells) and eliminate the latter. As the first line of defense against tumors and viral infections, NK cells can induce an antigen-independent immune response against malignant cells. The principles underlying NK cell therapy involve isolating and expanding these cytotoxic lymphocytes from either peripheral blood or umbilical cord blood, enhancing their anti-tumor activity through various means such as cytokine stimulation or genetic modification, and subsequently infusing them back into the body.

Features of NK Cell Therapy

Compared to T cells, NK cells have the advantages of greater viability, lower risk of side effects, and faster response rates, making the emerging NK-targeted immunotherapies an alternative for cancer populations who are not candidates for T-cell therapy.

• With an inherent ability to mediate cytotoxicity, NK cells can directly kill cancer cells without prior sensitization.
• Unlike T cells, NK cells are less likely to induce Graft-versus-Host Disease (GvHD) due to their limited capacity for antigen recognition.
• NK cells can be sourced from healthy donors, allowing for off-the-shelf availability and immediate therapy initiation.
• NK cell therapy can synergize with existing cancer therapeutics to improve overall efficacy through complementary mechanisms of action.

Our Services

Even though NK cell immunotherapy is highly effective and promising against many cancer types, there are still some limitations, including insignificant infiltration, adverse conditions of the microenvironment, etc. Alfa Cytology is committed to providing a comprehensive range of services and solutions, to help address potential barriers to the development of NK cell therapy. Our services include, but are not limited to, the following.
