Question

What is a naive B or T cell?

Step-by-Step Solution

Answer

A B cell or T cell, which is not exposed to an antigen is known as a naïve B or T cell.

Introduction:

Unless the lymphocytes, that is, the B cells and T cells come in contact and identify an APC or antigen-presenting cell and differentiated into effector cells, they are considered naïve cells. 

Explanation:

The naïve B cells are ineffective APCs and do not possess the tendency to stimulate the naïve T cells. The naïve B cells generally are found in primary lymphoid follicles in lymph nodes, mucosa-associated lymphoid tissue, and the spleen.
