The immune response is terminated or decreased by
|
|
suppressor B cells
|
|
|
suppressor T cells
|
|
|
both of the above
|
|
|
none of the above; the immune response can only be stimulated, not terminated
|
Explanation:
Detailed explanation-1: -A key finding of the study, published in Nature Immunology, are that these innate lymphoid cells can be shut off by certain cytokine chemicals-interferon-beta, -gamma and interleukin-27-to end the immune response and ensure that the inflammation does not last.
Detailed explanation-2: -Regulatory T cells (also called Tregs): suppress the actions of B and T cells to decrease the immune response when a highly active response is no longer warranted. Tregs control the immune response to self and foreign particles (antigens) and help prevent autoimmune disease.
