Verified step by step guidance1
Understand the role of T cells in the immune system. T cells are a type of lymphocyte that play a central role in cell-mediated immunity.
Identify the different types of T cells: Helper T cells (Th cells), Cytotoxic T cells (Tc cells), Regulatory T cells (Treg cells), and Natural Killer T cells (NKT cells).
Focus on Helper T cells (Th cells). These cells are crucial for activating and directing other immune cells, including B cells and cytotoxic T cells.
Helper T cells release cytokines that help B cells to produce antibodies and assist cytotoxic T cells in killing infected target cells.
Recognize that the term 'sensitized' refers to the process by which T cells become activated, but it is not a type of T cell. The correct type of T cell that assists other immune cells is the Helper T cell.
