Study Notes
Innate Immune Response
- The innate immune response recognizes "non-self" through DAMPs and PAMPs
- DAMPs (Danger-Associated Molecular Patterns) are from damaged cells: extracellular matrix, intracellular components (proteins, DNA/RNA, ATP)
- PAMPs (Pathogen-Associated Molecular Patterns) are from microbial structures: DNA/RNA, microbial structures
- Recognition of DAMPs or PAMPs triggers an alarm, activating cells (cytokines, chemokines, vasoactive and inflammatory agents)
- The alarm leads to local inflammation: heat, pain, redness, swelling
- Local inflammation is essential for tissue repair and regeneration
- Local inflammation recruits cells and factors to fight infection
- Systemic inflammation can also be triggered: fever, acute-phase response, metabolic shift, lymphocyte activation, neutrophil production
Adaptive Immune Response
- The adaptive immune response is a delayed response that requires learning
- The adaptive immune response is precise and tailored to the specific threat
- It is based on specialized training and generates memory
- The adaptive immune response generates B and T cells and antibodies
Course Overview
- This course covers both innate and adaptive immune responses as well as microbiology
- The course is divided into 5 exams and integrated sessions
- The exams are cumulative; review materials will be provided
Microbiology Overview
- Microbiology content includes bacteria, viruses, fungi, helminths, and protozoa
- There will be 8 questions for each pathogen on the exams
Pathogens
- Pathogens are cumulative and will be revisited on the final exam
- Integrate sessions at the end of the course will cover important organisms
The Immune Response
- The immune response is a complex process that involves many different cells, factors, and mechanisms
- The presence or absence of specific immune cells in tissue can help to diagnose diseases
- Immune cell accumulation is an indicator of the immune system activity
