Differentiate between the roles of B-lymphocytes and T-lymphocytes in generating immune responses.
OR
Principle of vaccination is bassed on the property of "memory" of the immune system. Taking one suitable example, justify the statement.

A

They scavenge damaged cells and cellular debris

B

These are produced in thyroid

C

There are three main types-cytotoxic T-cells, helper T-cells and suppressor T-cells

D

These originate in lymphoid tissues

Text Solution

Verified by Experts

The correct Answer is:
C
The function of T-cells is to provide immunity (cellular type) and not to scavenge damaged cells and cells debirs. These are produced in bone marrow and get matured in thymus gland. Hence, the only true statement is that there are three types of T-cells, i.e. cytotoxic, helper and suppressor.
