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

Measurements of Bcl-2 and CD25 expression suggested that IL-7R function is modified in CD4 lymphocytes of untreated viraemic patients. The extent of IL-7R function restoration post-HAART was analysed. A positive linear relationship was demonstrated between IL-7Ralpha expression and the magnitude of IL-7-induced responses in healthy individuals, whereas this relationship is lost in HIV-infected patients, suggesting that viraemic patients suffer a receptor signaling transduction defect in IL-7R function. IL-7 responsiveness is only partly restored by HAART.
