| GFAP | Supports cancer treatment planning through detailed analysis | Reflects tumor aggressiveness and potential response to therapy | Helps in distinct tumor classification |
Synaptophysin as a Marker in Medulloblastoma
Synaptophysin is a key protein found in medulloblastoma tissues. It shows how well the tumors are like neuroendocrine cells. This is very important for making treatment plans and figuring out what the tumor is.
Function of Synaptophysin
The main job of synaptophysin is to help make and release neurotransmitters. It’s found in cells that are either neurons or neuroendocrine. This makes it a key tool in medulloblastoma analysis to see where the tumor cells come from.
Detection Methods
To find synaptophysin in medulloblastoma, doctors use IHC detection methods. They use special tests called Immunohistochemistry (IHC). This test stains the tissue and shows where synaptophysin is.
| Detection Method | Description | Advantages | Limitations |
|---|---|---|---|
| Monoclonal Antibody-Based IHC | Uses specific antibodies to bind synaptophysin proteins. | High specificity and sensitivity | Possible cross-reactivity with other proteins |
| Enzyme-Linked Detection | Conjugates enzymes to antibodies for visualizing synaptophysin presence. | Enhanced signal amplification | Complex procedure that requires expertise |
| Fluorescent IHC | Uses fluorescent tags to detect synaptophysin. | Allows for multiplexing | Requires specialized imaging equipment |
Interpretation of Synaptophysin Results
When looking at synaptophysin in medulloblastoma analysis, the results tell us a lot. If the staining is strong and spread out, it means the tumor is more like neuroendocrine cells. This can help doctors know how to treat the patient.
NeuN: Its Significance in Medulloblastoma Diagnosis
