NK Cell-based Therapy Development Service for Bladder Cancer
Natural killer (NK) cells, a subset of immune effector cells known for their potent anti-viral and anti-tumor activity, have recently emerged as a promising candidate for cancer immunotherapy. Alfa Cytology is dedicated to providing innovative services in the development of NK cell therapy specifically tailored for bladder cancer.
Introduction to NK Cell-based Therapy
Natural killer cell therapy is a form of cellular immunotherapy, similar to CAR T-cell therapy. Like T-cells, NK cells are integral components of the immune system and exhibit cytotoxicity against pathogens and malignant cells. However, unlike T-cells, NK cells possess a non-specific antigen recognition capability, functioning as versatile effectors capable of identifying and eliminating aberrant cells. Occasionally, NK cells may be engineered with chimeric antigen receptors (CARs) to enhance their specificity towards cancerous cells. The operational mechanism of NK cells is as follows.
- Recognition and Killing of Cancer Cells
NK cells recognize infected or cancerous cells through activating and inhibitory receptors on their surface. Once an abnormal cell is identified, NK cells release perforins and granzymes, which disrupt the target cell membrane and induce apoptosis.
- Antibody-Dependent Cell-Mediated Cytotoxicity (ADCC)
NK cells enhance their cytotoxic activity by binding to antibody-coated cancer cells. This process relies on the FcγRIII receptor on the surface of NK cells.
- Cytokine Secretion
Upon activation, NK cells secrete various cytokines, such as IFN-γ and TNF-α, which can enhance the immune system's anti-tumor response.
