Memory cells are formed from
Memory cells are formed from
Open in App
Solution
The correct option is D Both C and D
T-lymphocytes
Sensitisation with antigens in secondary lymphoid organs causes the T lymphocytes to proliferate by dividing and differentiating into different types of cells based on the situation. Functionally T cells can be classified into regulator cells and effector cells.
All T cells are able to produce memory T cells. These cells remain in the lymphatic tissue and recognize the original invading antigen or pathogen, even after many years of the first encounter.
B-lymphocytes
Antigens trigger the B cells to divide and differentiate into plasma cells and memory B cells.
The plasma cells produce antibodies and secrete them into the lymph.
The memory B cells are the lymphocytes which are capable of memorising their first encounter with the antigen and can launch a very fast second response in case of subsequent encounters with the same antigen in future.
Final answer
(e.) Both C and D
