Mechanisms and Functions Model
Product Code : JC-BE-6123
The Mechanisms and Functions Model from Jaincolab is a three-dimensional teaching model that illustrates the mechanisms and functions of intercellular contacts made by lymphocytes, commonly referred to as the immunological synapse.
It is used in immunology and medical courses to explain how T cells and other lymphocytes engage antigen-presenting or target cells, and how the duration and strength of this contact determines the functional outcome.
What the Concept States
| Parameter | Details |
|---|---|
| Immunological Synapse | The organized point of contact formed between a lymphocyte and an antigen-presenting or target cell during antigen recognition |
| Adhesion Molecules | Molecules such as LFA-1 and ICAM-1 that stabilize the contact between a lymphocyte and its target cell |
| TCR-MHC Engagement | Binding of the T cell receptor to an antigen presented on an MHC molecule, initiating the intercellular contact |
| Contact Duration | The length of an intercellular contact can range from brief scanning contacts to prolonged, stable interactions needed for full T cell activation |
| Signal Transduction | Sustained contact allows intracellular signalling cascades to proceed, leading to lymphocyte activation |
| Functional Outcome | Depending on contact duration and signal strength, lymphocyte-target interactions can result in activation, tolerance, or target cell killing by cytotoxic T cells |

Frequently Asked Questions
Q1. What does the Mechanisms and Functions Model demonstrate?
A. It demonstrates the immunological synapse, the organized contact formed between a lymphocyte and an antigen-presenting or target cell, and the mechanisms that stabilize and regulate it.
Q2. What is the immunological synapse?
A. The immunological synapse is the organized point of contact formed between a lymphocyte and an antigen-presenting or target cell during antigen recognition.
Q3. What role do adhesion molecules play?
A. Adhesion molecules such as LFA-1 and ICAM-1 stabilize the contact between a lymphocyte and its target cell, allowing time for signalling to occur.
Q4. How does contact duration affect the outcome?
A. Longer, more stable contacts allow sustained signalling that can lead to full lymphocyte activation, while brief contacts may only support scanning or result in tolerance.
Q5. Who uses this model?
A. Immunology, medical, and biotechnology students and faculty use it to study lymphocyte intercellular contacts.
