Chronic infections in mice can result in defects in memory CD8 T cell properties including low expression of the IL-7Ralpha (CD127).

|
Compared to Flu, VV or EBV, HIV tetramer+ CD8 T cells expressed significantly lower levels of CD127, and this reduction was pervasive across all epitopes and alleles tested and over a wide range of viral loads and CD4 counts.

|
Our results show that in the absence of IL-7, IL-7Ralpha expression was extinguished on the majority of CD8 T cells responding to virus infection, sustained on a subset of effector cells transitioning to memory, and expressed at high levels by memory cells.

|
Thus, IL-7Ralpha regulation occurs independently of IL-7 in responding CD8 T cells, indicating that CD8 memory T cell precursors are not selected by IL-7/IL-7Ralpha interactions.

The early CCR5+CD38+++ vaccinia virus-specific CD4+ T cells were similar to our previous observations of human immunodeficiency virus (HIV)-specific CD4+ T cells in primary HIV type 1 (HIV-1) infection, but the vaccinia virus-specific cells expressed much more CD127 and IL-2 than we previously found in their HIV-specific counterparts.

|
We found that the percentage of T cells expressing IL-7R was significantly lower in both CD4(+) and CD8(+) T cell subsets in SIV-infected macaques than in healthy animals and this decrease directly correlated with the CD4(+) T cell number.

|
Importantly, the proportion of CD4(+) and CD8(+) T cells expressing IL-7R in blood paralleled that found in tissues.

|
The enhancement in the number of memory CD8 T cells in TNF-deficient (TNF-/-) mice was not associated with up-regulation of IL-7Ralpha or Bcl-2 in effector cells, which indicated that TNF might limit differentiation of memory cells from IL-7R(lo) effector cells.

|
This finding correlates with our observation that, upon recombinant lentivector immunization, a higher fraction of antigen-specific effector CD8+ T cells does not down-regulate the expression of the survival/memory marker interleukin-7 receptor alpha chain (IL-7Ralpha).

|
Here, we analyzed the reactivity of peripheral naive and memory conventional CD4(+)CD127(high) T cells (Tconv) of MS patients and healthy controls (HC) towards myelin basic protein (MBP), myelin oligodendrocyte glycoprotein (MOG) and tetanus toxoid (TT).

|
This reduction may have resulted from significantly reduced memory T cell expression of interleukin 2 receptor beta (IL-2R beta, CD122), but not IL-7 receptor alpha (CD127), which are both required for memory cell maintenance.
|

|
Compared to mice immunized with pcDS alone, CD44high and CD127(IL-7R) were all significantly up-regulated in memory CD8+ T cells from the mice immunized with pcDS combined CD137L both at a week and 12 weeks after immunization (P<0.05 and P<0.01).
|

|
The antigen-specific T cells exhibited the CD45RA(+) CCR7(+) precursor phenotype and the interleukin-7 receptor (CD127), which were different from the phenotype and receptor exhibited by the parental CD8(+) T-cell population.

|
To address these hypotheses, we measured frequencies of activated (CD38+ HLA-DR+), regulatory (CD4+CD25+CD127(dim)), HIV-specific, and CMV-specific T cells among HIV controllers and 3 control populations: HIV-infected individuals with treatment-mediated viral suppression (ART-suppressed), untreated HIV-infected "non-controllers" with high levels of viremia, and HIV-uninfected individuals.

|
The memory CD8(+) T cells also expressed high levels of CD27 and CD127, which are markers of long-term survival and maintenance of T cell memory.

We compared the effects of yeast-treated human dendritic cells (DCs) with CD40L-matured human DCs for the induction of effector cells and the number and functionality of CD4(+)CD25(+)CD127(-)FoxP3(+) regulatory T cells (Tregs).
