10 Questions
What was announced by the World Health Organization in 1979?
The eradication of smallpox
What is the function of variable antigen-specific receptors in adaptive immunity?
Undergoing gene segment rearrangements to produce effector cells
What occurs late in the immune response?
Clonal expansion of rare B cells and T cells
What type of receptors are used by the innate immune system?
Germline-encoded receptors
What is the result of gene segment rearrangements in adaptive immunity?
Variable antigen-specific receptors
What is the purpose of clonal expansion in adaptive immunity?
To increase the number of specific immune cells to combat infection
What is the role of B cells and T cells in adaptive immunity?
To undergo clonal expansion and differentiate into effector cells
What is the outcome of successful adaptive immunity?
The clearance of infection by effector cells
What occurs in the initial phases of the immune response?
Recognition of pathogens by germline-encoded receptors
What is the function of effector cells in adaptive immunity?
To migrate to the site of infection and clear the infection
This quiz covers the transport of antigens to lymphoid organs, dendritic cells, and the activation of the adaptive immune response. Learn about the two main arms of adaptive immunity: cell-mediated immunity and humoral immunity. Understand the structure of antibodies and T-cell receptors, and how antigens and epitopes interact with the immune system.
