Immunology of Infectious Diseases

The immune response to infectious agents is a complex interplay of innate and adaptive immunity. Upon encountering a pathogen, the innate immune system provides immediate, nonspecific defense mechanisms to limit the infection. Subsequently, the adaptive immune response is initiated, leading to the production of antigen-specific antibodies and T cells. Memory immune responses develop, providing long-term immunity upon re-exposure to the pathogen. Dysregulation of the immune response can result in immunopathology, leading to tissue damage and disease. Understanding the immunology of infectious diseases is crucial for developing vaccines and therapeutic interventions.
