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
