==T-Cell Dependent and Independent Responses==
==T-Cell Dependent and Independent Responses==
There are two types of B cell response to antigen. The T cell independent response does not require T cell help and the T cell dependent response does require T cell help.
There are two types of B cell response to antigen; one is dependant and the other independant of T cell interaction.
