Abstract:
Elucidation of the mechanism by which viral infection induces the appearance of carbohydrate neoantigens is highly important. Results from such studies could be expected to be significant for a general understanding of the regulation of glycosylation, and perhaps especially important for the understanding of glycosylation in cancer. For anti-viral therapy in AIDS, inhibitors of glycosylation enzymes are very promising as their mode of action may preclude evolvement of resistent HIV substrains, which seems to be a common problem with the reverse transcriptase inhibitors presently used. Successful therapy with glycosylation enzyme inhibitors will, however, require the development of more specific and less toxic compounds. If carbohydrate antigens can elicit a neutralizing immune response in vivo, the possibility exists that carbohydrate neoantigens can be utilized in the construction of a vaccine against AIDS.
Insights
Understanding how viral infections create new carbohydrate antigens is key for cancer research and developing AIDS vaccines. This knowledge may also lead to new anti-viral therapies by targeting glycosylation enzymes.
Area of Science:
- Glycoscience
- Virology
- Immunology
