Question

All of the following are true of dendritic cells EXCEPT ________.

a. they only process endogenous antigens
b. they are found under the surface of the skin and mucous membranes
c. they migrate to the lymph nodes after acquiring antigen
d. they are involved in antigen presentation

Answer 1

Dendritic cells are a type of antigen-presenting cell that can process both endogenous and exogenous antigens. They play a critical role in the adaptive immune response by presenting antigens to T cells.

Step-by-step explanation:

Dendritic cells are a type of antigen-presenting cell (APC) that play a critical role in the adaptive immune response. While all the statements provided are true of dendritic cells, the exception is choice a. They do not only process endogenous antigens. Dendritic cells can also process exogenous antigens, which are derived from external sources such as pathogens. By presenting these antigens to T cells, dendritic cells help initiate and regulate immune responses.
