What Are Natural Killer Cells? The Immune System’s First Responders Written by Dr. David Greene, MD, PhD, MBA Introduction The human immune system is a complex, multi-layered defense network that operates around the clock to protect us from pathogens, cancerous cells, and other threats. While much attention has been given to T cells and B cells […]

Adoptive NK Cell Transfer: Infusing Immunity to Fight Disease Written by Dr. David Greene, MD, PhD, MBA Introduction Adoptive cell transfer therapy involves taking immune cells — either from the patient or from a healthy donor — growing them in large numbers in a laboratory, and then infusing them back into a patient to fight disease.

Written by Dr. David Greene, MD, PhD, MBA Introduction Chimeric Antigen Receptor T cell therapy — better known as CAR-T — has been one of the most celebrated breakthroughs in oncology over the past decade. By genetically engineering T cells to carry a synthetic receptor that recognizes cancer-specific surface molecules, CAR-T therapy has achieved remarkable remissions

The Missing-Self Hypothesis: How NK Cells Tell Friend from Foe Written by Dr. David Greene, MD, PhD, MBA Introduction In the world of immunology, few concepts are as elegant — and as clinically important — as the missing-self hypothesis. First proposed by Dr. Klas Kärre in the 1980s, this theory explains how Natural Killer cells identify
