Binding of an antigen to the immunoglobulin receptor delivers the 1st signal to the B cell, which is usually insufficient.
For a second signal costimulatory molecules are required; the most important of which is antigen specific T cells.
1st the hapten is recognized by immunoglobulin receptor,
the hapten-carrier is then brought to the B cell and processed.
the peptide fragments of this carrier protein presented to a helper T cell.
Activation of the T cell results in the production of cytokines that enable the hapten-specific B cell to become activated to produce soluble anti-hapten antibodies.

The superantigens bypass the step 2!
i.e., they can activate the T cells directly.
These antigens need not be processed by B cells to make it presentable to the T cells |
| Quote: |
In EB virus infection,the B cells gets activated directly.
This activation is independent of the T cells (as described above),therby the EB infected cells become immortal,as they no longer depend on cytokines for its activation.

Hepatitis B surface antigen is the earliest indicator of acute infection and is also indicative of chronic infection if its presence persists for more than 6 months. It is useful for the diagnosis of HBV infection and for screening of blood.
