Explain the mechanism of action of T cells to antigens.

Explanation

### Step-by-Step Text Solution:

1. **Introduction to T-cells**:
T-cells are a type of lymphocyte, which are crucial components of the immune system. They play a significant role in identifying and responding to antigens, which are foreign substances that provoke an immune response.
