Immunology and Biotherapies

In a recent study published in the journal Nature, researchers have compiled the available literature on natural killer (NK) cells, innate immune cells involved in the recognition and elimination of cells in distress, particularly virus-infected cells and tumors. They focus on reviewing current preclinical and clinical research in the field of NK therapies, primarily elucidating the role of NK cells in cancer immunity. They also explore the potential of bioengineering approaches to harness NK cells via the development of genetically modified NK cells, immune checkpoint inhibitors and cell engagement agents. The study reveals that, despite less than two decades of research in the field, NK cells are emerging as a safe, practical and potentially widely accessible means of clinical therapy, particularly antitumor. Although challenges exist in the adoption of NK cell therapies by conventional medicine, studies aimed at overcoming these challenges are already underway, bringing the future of clinical NK cell interventions closer than ever.
