Helper or suppressor cells are types of which of the following?
A
T lymphocytes
B
B lymphocytes
C
Macrophages
D
Erythrocytes
Verified step by step guidance1
Step 1: Begin by understanding the role of helper and suppressor cells in the immune system. Helper cells (also known as helper T cells) assist other immune cells in responding to infections, while suppressor cells (also known as regulatory T cells) help regulate or suppress immune responses to prevent overactivity.
Step 2: Recall that T lymphocytes (T cells) are a type of white blood cell that plays a central role in the adaptive immune system. They include various subtypes such as helper T cells (CD4+ cells) and suppressor T cells (regulatory T cells).
Step 3: Compare the other options provided: B lymphocytes are responsible for producing antibodies, macrophages are involved in phagocytosis and antigen presentation, and erythrocytes are red blood cells responsible for oxygen transport. None of these are directly involved in the roles of helper or suppressor cells.
Step 4: Recognize that helper and suppressor cells are specific subtypes of T lymphocytes, which are distinct from B lymphocytes, macrophages, and erythrocytes.
Step 5: Conclude that the correct answer is T lymphocytes, as they encompass both helper and suppressor cells within the immune system.
