21. Also, iPS cells expressed cell surface antigenic markers expressed on ES cells. 22. I think this technique was created before immunologist really understand about antigenic determinants. 23. This leads to the presentation of viral antigenic peptides absent from normal cells. 24. A hapten is a small molecule that changes the structure of an antigenic epitope. 25. G protein spikes out of the membrane and acts as a major antigenic determinant. 26. Neuraminidase is an antigenic glycoprotein enzyme found on the surface of the influenza viruses. 27. The problem of antigenic escape has greatly deterred the process of creating new vaccines. 28. One increasingly worrying situation is the possible antigenic shift between avian influenza and human influenza. 29. Antigenic drift occurs in both and viruses.30. Later during development, individual TCR revision ( editing ) and change its antigenic specificity.
