The immune response is a defense mechanism comprised of a complex network of interacting molecules and cells which function to recognize and respond to agents foreign to the individual. This course focuses on the biochemical mechanisms that act at the molecular and cellular levels to regulate this process. Textbook readings will be supplemented with current literature. Format: lectures, three hours a week; laboratory: three hours every other week. Evaluation will be based on two hour exams, a comprehensive final exam, a comprehensive lab report, and a research paper. Prerequisite: Biology 202. Enrollment limit: 40 (expected: 40). Preference given to seniors and Biology majors and BIMO concentrators.
