V gamma 9V delta 2 T-cell anergy and complementarity-determining region 3-specific depletion during paroxysm of nonendemic malaria infection

Infect Immun. 2003 May;71(5):2945-9. doi: 10.1128/IAI.71.5.2945-2949.2003.

Abstract

V gamma 9V delta 2 T lymphocytes strongly respond to phosphoantigens from Plasmodium parasites. Thus, we analyzed the changes in V gamma 9V delta 2 T-cell function and repertoire during the paroxysm phase of nonendemic malaria infection. During malaria paroxysm, V gamma 9V delta 2 T cells were early activated but rapidly became anergic and finally loose J gamma 1.2 V gamma 9 complementarity-determining region 3 transcripts.
