Chapter 5: Immunopathology

In this video for medical students, I review the mechanisms of autoimmunity and then discuss two representative diseases: rheumatoid arthritis and systemic lupus erythematosus.

This video for medical students compares and contrasts the different types of hypersensitivity and provides context for the diseases that are caused by this dysfunction of the immune system.

This video for medical students covers 1) key concepts in the mechanisms of transplant rejection and 2) compares and contrasts the four types of rejection seen in solid organ transplants: hyperacute, acute cellular, acute antibody-mediated (humoral) and chronic. There is also a brief discussion of hematopoietic stem cell transplantation.
