PREPARATION
What is immunology?
The study of the physiological mechanisms that humans and other animals use to
defend their bodies from invasion by other organisms.
Who conducted the first immunological experiment?
Dr. Edward Jenner
What disease did Dr. Edward Jenner's vaccination aim to eradicate?
Smallpox
What is the estimated death toll of smallpox in the 20th century?
300 million deaths
What does the term 'vaccine' derive from?
The cowpox virus vaccinia, which comes from the Latin word 'vacca' meaning cow.
What are the two main types of immunity?
Innate immunity and adaptive immunity.
What is hematopoiesis?
The process by which hematopoietic stem cells differentiate into mature blood cells.
What are the two capacities of stem cells?
The ability to regenerate (self-renew) and the ability to differentiate into diverse cell
types.
What are the first responders to multiple extracellular pathogens?
Granulocytes, including neutrophils, eosinophils, basophils, and mast cells.
What is the role of phagocytic cells in the immune response?
They detect pathogens and trigger innate immunity.
What happens in secondary lymphoid structures during an immune response?
T helper cells, T cytotoxic cells, and B cells proliferate and differentiate.
What is the effector phase of an immune response?
When T and B cells migrate toward the infection site to help destroy remaining
pathogens.
What is the significance of memory cells in the immune system?
They are generated to provide long-term immunity against previously encountered
pathogens.
What is the function of T helper cells?
They assist in the activation of B cells and other immune cells.
What is the function of T cytotoxic cells?
They kill infected cells and cancer cells.
What are lymphoid organs?
Organs that are part of the immune system, such as lymph nodes and the spleen.
What is the role of B cells in the immune response?
They produce antibodies that target specific pathogens.
,What is the difference between innate and adaptive immunity?
Innate immunity is the body's first line of defense, while adaptive immunity is a specific
response developed over time.
What are the temporal phases of the immune response?
Recognition of the pathogen, activation of immune cells, and the effector phase.
What is the importance of pathogen recognition systems?
They allow the immune system to identify and respond to foreign invaders.
What is the function of granulocytes?
They are involved in the innate immune response and help fight infections.
What is the significance of the phrase 'immunis' in relation to immunity?
It means exempt or free, referring to the body's ability to resist disease.
What are the components of the immune system?
Cells such as phagocytes, T cells, B cells, and various signaling molecules.
What is the role of lymphatic vessels in the immune response?
They transport immune cells and pathogens to lymph nodes for processing.
What is the primary goal of immunological research?
To maintain the balance of immune responses and prevent unwanted immune
reactions.
What is the relationship between vaccines and immunity?
Vaccines stimulate the immune system to develop memory against specific pathogens.
What are the two main lineages of immune cells?
Myeloid and lymphoid lineages.
What type of immune cells are included in the myeloid lineage?
Granulocytes and phagocytes, including neutrophils, eosinophils, basophils, and mast
cells.
What is the role of granulocytes?
They are the first responders to extracellular pathogens and release granule contents to
impair pathogen activity.
What do macrophages and dendritic cells do?
They can activate T lymphocytes and are potent antigen-presenting cells.
What are the two main types of lymphocytes?
B cells and T cells.
What is the function of B cells?
They produce antibodies and can present antigens to T cells.
What are the two types of T cells?
CD4+ helper T cells and CD8+ cytotoxic T cells.
What is the role of Natural Killer (NK) cells?
They provide defense against viruses, bacteria, and tumor cells.
What is the primary function of dendritic cells?
To activate T cells as antigen-presenting cells and bridge innate and adaptive immunity.
What are the two arms of immunity?
Innate immunity and adaptive immunity.
What characterizes innate immunity?
It is immediate and includes myeloid cells and NK cells.
What characterizes adaptive immunity?
It is delayed, involves T and B cells, and generates memory cells.
, What are the four characteristics of adaptive immune responses?
Specificity, diversity, self-tolerance, and memory.
What does specificity in the immune response refer to?
The ability of immune cells to recognize particular antigens with high precision.
How does the immune system achieve diversity?
By being able to recognize ten million or more different antigens.
What is self-tolerance in the immune system?
The ability to become nonresponsive to self-antigens.
What is immune memory?
The faster and stronger immune response upon a second encounter with an antigen.
Where do immune cells develop?
In primary lymphoid organs such as the bone marrow and thymus.
Where do immune responses occur?
In secondary lymphoid organs like lymph nodes and the spleen.
What is the role of phagocytes?
To engulf and destroy pathogens.
What is the function of pattern recognition receptors?
To help innate cells discriminate between self and non-self.
What is antigen-specific recognition?
Recognition of specific antigens by adaptive immune cells (B and T cells).
What is pattern-dependent recognition?
Recognition by innate immune cells based on common patterns found in pathogens.
What is clonal selection?
The process by which specific lymphocytes are activated and proliferated in response to
an antigen.
What is immunity? -ANSWER✅✅✅The ability of the body to defend against infection
and disease (free from burden)
What is immunology? -ANSWER✅✅✅The study of host defenses against infectious
disease and cancer and the undesirable consequences of immune interactions
What is the first line of defense in the immune system? -ANSWER✅✅✅Physical and
chemical barriers
What makes the skin antimicrobial? -ANSWER✅✅✅Low pH and fatty acids
What is the role of cilia in the lungs? -ANSWER✅✅✅Move mucus to trap and remove
pathogens
What is the function of mucus in the respiratory system? -ANSWER✅✅✅Traps
microorganisms
What is the antimicrobial component found in saliva? -ANSWER✅✅✅Lysozyme
