Course Description: In this course, we will examine how the immune system acts to destroy pathogenic invaders while tolerating colonization by necessary commensal bacteria. As a counterpoint, we will also explore sophisticated strategies that help some bacteria evade our immune system. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching.
