Question

Quizplus · Accepted Answer

This statement is true. Helper T lymphocytes, also known as CD4+ T cells, recognize and interact with antigens that are presented with class-2 major histocompatibility complex (MHC) molecules. Class-2 MHC molecules are found on the surface of antigen-presenting cells, such as dendritic cells, macrophages, and B cells, and they are responsible for presenting foreign antigens to T cells. Helper T cells play an important role in activating other cells of the immune system, such as B cells and cytotoxic T cells, to mount an effective immune response against foreign invaders.
