Step 1

Step 1: T cells interact with antigens presented by macrophages

96%

114 rated

Answer

This is the initial interaction where T cells recognize and bind to antigens presented by antigen-presenting cells, such as macrophages.

Step 2

Step 2: Activated T cells differentiate into helper T cells

99%

104 rated

Answer

Once the T cells are activated, they differentiate into helper T cells, which play a crucial role in orchestrating the immune response.

Step 3

Step 3: Helper T cells produce chemicals that cause B cells to multiply

96%

101 rated

Answer

The activated helper T cells release cytokines that stimulate B cells to proliferate and differentiate into plasma cells.
