Immunology is the study of the immune system and how it functions to protect the body from foreign invaders.
What are the two main types of immunity?
The two main types of immunity are innate immunity and adaptive immunity.
What is autoimmunity?
Autoimmunity is when the immune system attacks the body's own cells and tissues, mistaking them for foreign invaders.
What are the four major types of leukocytes involved in the immune response?
The four major types of leukocytes involved in the immune response are B cells, T cells, natural killer cells, and phagocytes.
What is the role of antibodies in the immune response?
Antibodies identify and neutralize foreign invaders by binding to them and marking them for destruction by other cells in the immune system.
What is vaccination?
Vaccination is the process of introducing a small, harmless dose of a disease-causing agent into the body in order to stimulate an immune response and provide immunity to the disease.
What is the difference between an antigen and an antibody?
An antigen is a foreign substance that stimulates an immune response, while an antibody is a protein produced by the immune system in response to the presence of an antigen.
What is the complement system?
The complement system is a group of proteins in the blood that work together to identify and destroy foreign invaders.
What is inflammation?
Inflammation is a natural immune response to injury or infection, characterized by redness, swelling, warmth, and pain.
What is the function of memory cells?
Memory cells are specialized cells that remain in the body after an initial immune response and allow for a quicker and more effective response to future infections from the same pathogen.
What is herd immunity?
Herd immunity is when a significant proportion of a population is immune to a disease, either through vaccination or previous infection, which provides indirect protection to those who are not immune.
What is the role of cytokines in the immune response?
Cytokines are proteins that act as signaling molecules in the immune response, regulating the behavior of immune cells and coordinating their activities.
What is the difference between active and passive immunity?
Active immunity is when the body's immune system produces its own antibodies in response to a pathogen, while passive immunity is when pre-formed antibodies are given to the body from an external source.
What is immunosenescence?
Immunosenescence is the age-related decline in immune function that occurs in elderly individuals, leading to increased susceptibility to infection and disease.
What is the role of dendritic cells in the immune response?
Dendritic cells are specialized immune cells that present antigens to T cells in order to initiate an adaptive immune response.
What is immunology?
Immunology is the study of the immune system and how it functions to protect the body from foreign invaders.
