MIDTERM PT 2 Flashcards
Immunity that involves the antibodies which are produced by the B cells.
- Production of antibodies
HUMORAL IMMUNITY
Immunity that involves the T cells which are the ones recognizing the antigens.
CELL-MEDIATED IMMUNITY
It trigger the production of antibodies.
- Present in microbes/microbial cell
ANTIGENS
It is produced by the B cells. They are globular proteins (immunoglobulins) made in response to an antigen.
- Y-shaped
ANTIBODIES
It is specialized and can adapt to match the shape of the antigen.
- Antigen-binding site
FAB REGION
It binds to the phagocytes.
FC REGION
Antibody found in mucous, saliva, tears, and breast milk. Protects against pathogens.
IgA
It protects against parasitic worms. Responsible for allergic reactions.
IgE
It is secreted by plasma cells in the blood. Able to cross the placenta into the fetus.
- Most abundant immunoglobulin
IgG
It is the biggest antibody (macroglobulin)
- May be attached to the surface of a B cell or secreted into the blood.
IgM
It is found on the surface of the B cells.
IgD
A role of antibodies where the antibody will bind to the spike proteins; microbes will be inhibited from entering the host cell.
NEUTRALIZATION
Role of antibody where clumping occurs and reduces the number of infectious units.
AGGLUTINATION
Role of antibody where coating the microbes occur
OPSONIZATION
The cross-linking of NK cell
ANTIBODY-MEDIATED CELLULAR TOXICITY
It is also known as CD4+ T cells, come in different subtypes stimulate the differentiation of B cells to produce cytotoxic cells.
HELPER T CELLS
It is also known as the CD8+ cells are able to lyse and induce apoptosis (cell death); the body’s main defense against intracellular pathogens.
CYTOTOXIC T CELLS
Antigen-presenting cells
DENDRITIC CELL
antigens enter the body naturally; body induces antibodies and specialized lymphocytes.
NATURALLY ACQUIRED ACTIVE IMMUNITY
antibodies pass from mother to fetus via placenta or to infant via the mother’s milk.
NATURALLY ACQUIRED PASSIVE IMMUNITY
preformed antibodies in immune
serum are introduced by injection.
ARTIFICIALLY ACQUIRED PASSIVE IMMUNITY
antigens are introduced in vaccines; body produces antibodies and specialized lymphocytes.
ARTIFICIALLY ACQUIRED ACTIVE IMMUNITY
Adapts to specific microbe or foreign substance.
Associated with a person’s memory of the infection.
ADAPTIVE IMMUNITY
a biological preparation that enhances your immune system to produce antibodies in order to kill or neutralize the disease-causing microbe.
VACCINE
functions of helper t cells
ACTIVATE MACROPHAGE AND CYTOTOXIC T CELL
HELP ACTIVATE B CELL
RECRUIT NEUTROPHILS AND MACROPHAGE
