Verified step by step guidance1
Understand the role of helper T cells in the immune system. Helper T cells are a subset of T cells that play a crucial role in the immune response by activating other immune cells.
Identify the different types of helper T cells: TH1, TH2, and TH17. Each type has a specific role in the immune response.
TH1 cells are primarily involved in the response against intracellular pathogens, such as viruses and some bacteria, by activating macrophages.
TH2 cells are involved in the response against extracellular pathogens, such as parasites and allergens, by stimulating B cells to produce antibodies.
TH17 cells also play a role in fighting extracellular pathogens, particularly fungi and bacteria, by recruiting neutrophils and promoting inflammation.
