They organise themselves in small clusters which are transported by actin in the direction of the centre of the synapse. In this way, activation of T-cells may be induced or slowed down, which could be used for improved management of acute or chronic infections, improved results from vaccination or prevention of autoimmune diseases.

As a next step, Semb and his team found new ways to specifically promote the proliferation of these beta cell precursors. The loose bond formed between the two cell surfaces allows for the binding of T-cell receptors to the presented antigen. From a medical point of view, these results are of particular significance for the area of treatment of defective T-cell activity.

    This, however, could not be proved for the other molecules.

    At the end of this process the T-cell is either activated or remains inactive.

    The T-cell makes contact with the antigen-presenting cell by means of specialized adhesion molecules which initially are randomly distributed over the cell surface.

In these models, they simulated different conditions and influencing factors and were able to demonstrate that the different molecules exert an influence on each other in terms of their arrangement although they do not interact directly.

    Robert, Philippos Demetriou, Michael L. To achieve this, however, immune cells must be able to recognise intruders and to classify them as dangerous or harmless. The large adhesion molecules accumulate around them in an outer ring.

    1. Both cells form a characteristic ring-shaped structure at their contact point, the immunological synapse, through which they exchange information.

    2. The T-cell makes contact with the antigen-presenting cell by means of specialized adhesion molecules which initially are randomly distributed over the cell surface.

    3. If one of these cells meets a foreign body, it will integrate parts from it — called antigens — onto its own cell surface and present these to other immune cells: These tasks are shared among different cell types:
