T cells and B cells are two types of white blood cells that play a vital role in the body's adaptive immune response. Originating in the bone marrow, B cells mature there, while T cells migrate to the thymus to complete their maturation process. Despite their structural similarities, these cells differ in terms of their roles and functions in the immune system.

Let's delve deeper into the differences between T cells and B cells.
B cells, which mature in the bone marrow, are responsible for producing antibodies that respond to invading antigens. These cells play a crucial role in the body's humoral response. Upon encountering antigens, B cells generate plasma cells and memory B cells.
T cells, on the other hand, mature in the thymus after originating in the bone marrow. They can be further categorized into T helper cells and T cytotoxic cells. T cells are tasked with eliminating pathogens from the body. When a foreign antigen invades a cell, T cells stimulate B cells to produce plasma cells and activate T killer cells that destroy the infected cells.

Where are B and T cells located?
The B and T cells originate in the bone marrow and mature in the bone marrow and thymus respectively.
How do the T cells activate?
The T helper cells are activated when they are presented with the antigens by the MHC Class II molecules that are expressed on the surface of antigen presenting cells.
