Immunity & Immunization
100

Type of receptor that is found on all nucleated human cells and marks those cells as "self".

What is Class I MHC?

100

The site of T cell maturation.

What is the thymus?

100

The site of B cell maturation.

What is bone marrow?

100

When antibodies bind to viral surface receptors and prevent it from attaching to a host cell.

What is neutralization?

100

Type of immunity when a child is vaccinated against measles.

What is artificial active immunization?

200

Type of receptor that consists of two parallel polypeptide chains and has variable regions that contain antigen-binding sites?

What is a T-cell receptor?

200

The type of immunity carried out by T cells involving direct killing of infected cells.

What is cell-mediated immunity?

200

Type of immunity carried out by B cells involving antibodies.

What is humoral immunity?

200

When antibodies bind to a toxin before it causes cellular damage.

What is antitoxin?

200

Type of immunity when a mother is breastfeeding her baby.

What is natural passive immunity?
300

Type of receptor exclusively found on macrophages, dendritic cells, and B cells.

What is Class II MHC?

300

The most prevalent type of T cell that activates other T and B cells.

What is a T Helper (CD4) cell?

300

Differentiated B cell that produces large quantities of a single type of antibody.

What are plasma cells?

300

Process when antibodies aggregate and cross-link cells/particles into clumps.

What is agluttination?

300

Type of immunity when a threshold level of the population is immune to a pathogen, making it less likely for a non-immunized person to encounter the pathogen.

What is herd immunity?

400

Type of receptor with two heavy chains and two light chains that serves as a cell surface receptor and as an antibody.

What is an immunoglobulin?

400

Proteins secreted by cytotoxic T cells that punch holes in target cell membranes.

What are perforins?

400
A type of B cell that is specific to a certain antigen and remains in lymphatic circulation for a long period of time (decades to lifetime).

What is a memory B cell?

400

The process of antibodies coating a microbe or particle to make it more recognizable to a phagocyte.

What is opsonization?

400

Type of vaccine that contains a live organism with reduced or eliminated virulence.

What is a live attenuated vaccine?

500

Type of receptor that works with a T-cell receptor to provide cell adhesion and communication for a T helper cell.

What is CD4?

500

A cell related to T cells that secretes perforins and granzymes but lack specificity.

What are natural killer (NK) cells?

500
Process that occurs after a B cell binds a specific antigen to make more cells with that same type of receptor.
What is clonal selection and expansion?
500

The type of antigenic exposure that results in a larger production of IgG antibodies that last for a longer period of time.

What is the secondary response?

500

Type of vaccine that includes a non-pathogen carrier that has been engineered to contain pathogen genetic material.

What is a recombinant vaccine?
