What are chemokines?
A family of homologous cytokines that promote the migration of white blood cells
(WBCs) through chemotaxis.
What is the role of interleukins (IL) in the immune response?
They regulate the adaptive immune response and inflammation process, affecting
growth, mobility, and differentiation of lymphoid cells.
What is the function of interferons (INF)?
Cytokines produced by T cells that inhibit viral synthesis and act as immune regulators.
What does a lack of agglutination indicate in serological tests?
It indicates a negative result for the presence of antigen or antibody.
What is humoral immunity?
A branch of adaptive immunity carried out by soluble factors (antibodies) found in
serum.
What are plasma B cells?
The most mature and differentiated B cells responsible for antibody production.
What is the role of memory B cells?
They are long-lived B cells that respond quickly to reinfection with the same microbe.
Where does B cell differentiation take place?
In the bone marrow.
What is the Major Histocompatibility Complex (MHC)?
A major player in antigen presentation in the immune system.
What activates CD8+ T cells?
Class I MHC molecules presenting endogenous antigens.
What activates CD4+ T cells?
Class II MHC molecules presenting exogenous antigens.
What are the stages of T cell differentiation?
1. Double-negative stage (lacking CD4, CD8), 2. Double-positive stage (CD3+, CD4+,
CD8+), 3. Single-positive stage (CD3+ and CD4 or CD8).
What is the main role of T cells?
Antigen presentation and activation of other immune cells.
What is the function of regulatory T cells?
To suppress immune responses and inhibit the proliferation of other T cells.
What is the significance of CD markers?
Cluster of differentiation markers are added during T cell differentiation and help identify
specific T cell types.
What is the difference between endogenous and exogenous pathways in T cell
activation?
Endogenous pathways activate CD8+ T cells with intracellular antigens, while
exogenous pathways activate CD4+ T cells with extracellular microbes.
What is the role of antigen-presenting cells (APCs)?
APCs display peptide antigens to T cells via MHC molecules.
What type of immunity is carried out by T cells?
,Cell-mediated immunity.
What happens to T cells in circulation before they encounter an antigen?
They are considered naive, as they have not yet encountered an antigen.
What is the main function of helper T cells?
To stimulate B cells to produce antibodies and activate other T cells.
What is the primary function of cytotoxic T cells?
To produce toxic agents that kill their target cells.

Immunology -ANSWER✅✅✅Study of a host's reactions when foreign substances are
introduced into the body
Antigens -ANSWER✅✅✅Foreign substances that induce a host response
Immunity -ANSWER✅✅✅The condition of being resistant to infection
Edward Jenner -ANSWER✅✅✅Successfully prevented infection with smallpox by
injecting a more harmless substance- cowpox from a disease affecting cows
Louis Pasteur -ANSWER✅✅✅Father of immunology- observed by chance that older
bacterial cultures would not cause diseases in chickens (first attenuated vaccine)
Used attenuation to prevent rabies in affected individuals
Attenuation -ANSWER✅✅✅Change- make a pathogen less virulent (heat, aging, or
chemical means)
Phagocytes -ANSWER✅✅✅Cells that eat- part of natural or innate host defense
humoral immunity -ANSWER✅✅✅specific immunity produced by B cells (plasma cells)
that produce antibodies that circulate in body fluids
Antibodies -ANSWER✅✅✅Serum proteins produced by certain lymphocytes when
exposed to a foreign substance and they react specifically with that foreign substance
Innate (natural) immunity -ANSWER✅✅✅The individual's ability to resist infection by
means of normally present body functions
Adaptive immunity -ANSWER✅✅✅Type of resistance that is characterized by
specificity for each individual pathogen, or microbial agent, and the ability to remember
a prior exposure
increased response to that pathogen upon repeated exposure
