🔖Practice question #64
A peripheral T-helper lymphocyte engages peptide-bound class II MHC molecules on the surface of an antigen-presenting cell (APC). The only signal received is from the MHC II complex. No other contact is made between cell surface molecules present on the T lymphocyte and the APC. Which of the following can be concluded about this peripheral T lymphocyte?
A) The T lymphocyte will be activated and fully able to perform effector functions
B) The T lymphocyte will be activated but unable to perform effector functions
C) The T lymphocyte will cause the APC to undergo apoptosis
D) The T lymphocyte will undergo anergy
E) The T lymphocyte will undergo clonal expansion
