Question:
The cells which stimulate B-lymphocytes to produce antibodies are known as
The cells which stimulate B-lymphocytes to produce antibodies are known as
Show Hint
Helper cells that carry the CD4 marker release cytokines which activate B-cells.
Updated On: Nov 12, 2026
- Killer B-cells
- Helper B-cells
- Helper T-cells
- Suppressor T-cells
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
B-lymphocytes make antibodies only after they are activated and change into plasma cells.
Step 2: Who activates them
Helper T-cells (\(\text{CD4}^{+}\)) recognise the antigen and release cytokines, which stimulate B-cells to divide and produce antibodies.
Step 3: Other cells
Killer (cytotoxic) T-cells destroy infected cells and suppressor T-cells reduce the immune response. There are no 'killer B-cells' or 'helper B-cells' in the immune system.
Final Answer:
Helper T-cells stimulate B-lymphocytes to produce antibodies. \[ \boxed{\text{(C) }\text{Helper T-cells}} \]
