A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Virus VIH-1 (HIV-1), responsable du sida. Première étape de pénétration dans la cellule. Le virus s'approche du lymphocyte T4 et arrive à proximité de son point d'ancrage le récepteur CD4 qui reconnaît spécifiquement la protéine d'enveloppe virale gp120. On voit nettement le manteau de clathrine qui participe au processus d'endocytose (Grossissement X 190000). Image colorisée.

Both differentiation and function of CD4+CD25(high) naturally arising regulatory T cells (Treg), which play a key role in the control of autoimmunity, are thought to depend on TCR specificity. In the present study, we comparatively measured the alphabetaTCR repertoire sizes of human peripheral blood Treg and CD4+CD25- T cells by using a methodology based on PCR amplification and sequencing analysis. We show that Treg use a large unrestricted alphabeta TCR repertoire, the size and diversity of which are closely similar to those of CD4+CD25- T cells, with a mean estimated size of 3.5 x 10(6) distinct alphabeta TCR vs 4.7 x 10(6) distinct alphabetaTCR for CD4+CD25- T cells. In addition, a 24% overlap between the repertoires of these two CD4+ subsets in the periphery is found. These data emphasize the intersection between naturally occurring Treg and effector T cell peripheral repertoires and provide new insights into the ontogeny of Treg in humans.
