GD2 is an amphiphilic molecule consisting of a hydrophobic ceramide tail (which anchors it to the cell membrane) and a hydrophilic oligosaccharide head containing two sialic acid residues .
Found on cancer stem cells in these aggressive subtypes.
Vaccines aim to stimulate the patient's own immune system to produce anti-GD2 antibodies, while small DNA/RNA molecules (aptamers) are being researched to deliver drugs directly to GD2-positive cells. Diagnostic Significance gd2.zip
T-cells are engineered to recognize and kill GD2-expressing cells. This has shown significant promise in clinical trials for pediatric brain tumors.
GD2 levels can be monitored via (blood or serum tests) to track disease progression or response to treatment. Higher levels of circulating GD2 often correlate with more aggressive disease and poor prognosis. GD2 is an amphiphilic molecule consisting of a
In healthy adults, GD2 expression is restricted to the brain , peripheral nerves, and skin melanocytes. Role in Cancer
Present in over 98% of cases; it is a standard diagnostic and therapeutic target. Higher levels of circulating GD2 often correlate with
It is synthesized in the Golgi apparatus from precursors like GM3 and GD3. Key enzymes in this pathway include ST8SIA1 (GD3 synthase) and B4GALNT1 (GD2 synthase).
