Question

Which of the following effector T lymphocyte populations is produced via the activation of a naive T cell through antigen presented in MHC Class I?

1) CTL
2) TH1
3) TH₂
4) TH17
5) None of the above

Answer 1

The effector T lymphocyte population produced via the activation of a naive T cell through antigen presented in MHC Class I is CTL (cytotoxic T lymphocytes).

Step-by-step explanation:

The effector T lymphocyte population that is produced via the activation of a naive T cell through antigen presented in MHC Class I is the CTL (cytotoxic T lymphocyte).

When a naive CD8+ T cell interacts with an antigen presented in MHC Class I on an antigen-presenting cell (APC), it becomes activated and differentiates into cytotoxic T lymphocytes (CTLs).

CTLs have the ability to directly kill infected cells by inducing apoptosis and also emit cytokines to amplify the immune response.
