T-cell receptor sequencing

T-cell receptor sequencing is a laboratory technique that analyzes the unique receptors on T cells, a type of immune cell. These receptors help T cells recognize and fight infections or abnormal cells. By sequencing these receptors, scientists can identify the diversity and specific patterns of T cells present in a person’s body. This helps in understanding immune responses, tracking diseases like cancer or infections, and developing targeted therapies. Essentially, it provides a detailed “map” of the immune system’s T cells, revealing how the body is defending itself or responding to treatment.
