What is the Role of Biological Agents in Disease Pathogenesis?
Biological agents play a crucial role in the pathogenesis of diseases. They can directly damage tissues or elicit an immune response that leads to tissue injury. For example, the presence of Helicobacter pylori in the stomach lining is associated with peptic ulcers and gastric cancer. Similarly, the Human Papillomavirus (HPV) is linked to cervical cancer.
