Toxic shock syndrome toxin-1 is produced by some strains of S. aureus
and is thought to be responsible for the clinical manifestations of disease by
this organism. This toxin is referred to as a superantigen because it can
a. Activate T cells in an antigen-nonspecific manner
b. Activate B cells without T cell help
c. Become immunogenic when attached to a carrier protein
d. Prolong the presence of antigen in a tissue
e. Evoke IgE
