Killer T Cells: Immune System Heroes

Abstract

This article is based on an interview between the two authors.The human body is like a jungle, with trillions of fascinating things happening inside it every second, most of which occur without our awareness. In this article, we will zoom in on a very interesting part of this jungle of human-body activities—the immune system. The immune system protects the body from intruders with its experts in martial arts, called killer T cells. Killer T cells are responsible for eliminating virus-infected cells so that the virus cannot reproduce itself and spread throughout the body. Join me for an adventurous journey into the immune system, in which we will find out how killer T cells know which cells to attack and which to leave alone.
