Oral immunization with a Salmonella enterica serovar typhi vaccine induces specific circulating mucosa-homing CD4(+) and CD8(+) T cells in humans.

|
Eight volunteers were each given three doses of the vaccine 2 days apart, and blood samples, from which CD4(+) and CD8(+) T cells were selected by the use of magnetic beads, were collected before vaccination and at regular intervals thereafter.
|

|
The responses were seen among both CD4(+) and CD8(+) T cells, although the CD8(+) cells produced the largest amounts of IFN-gamma.
|

|
Furthermore, most of the IFN-gamma produced by both CD4(+) and CD8(+) cells emanated from cells with the potential to home to mucosal tissues, as the integrin beta(7)-expressing memory T cells produced around 10-fold more IFN-gamma than the remaining populations.

|
In conclusion, we demonstrate that oral vaccination with a live oral bacterial vaccine induces antigen-specific CD4(+) and CD8(+) memory T cells, almost all of which express the gut-homing integrin beta(7).

Membrane-anchored C-peptides (for example, maC46) derived from human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein gp41 effectively inhibit HIV-1 entry in cell lines and primary human CD4+ cells in vitro.

|
Depletion of CD8+ T cells from PBMCs enhanced the yield of maC46-transduced CD4+ T cells.

|
Supplementation with interleukin-2 (IL-2) increased transduction efficiency, whereas IL-7 and/or IL-15 provided no additional benefit.
|

|
Phenotypic analysis showed that maC46-transduced and expanded cells were predominantly central memory CD4+ T cells that expressed low levels of CCR5 and slightly elevated levels of CD62L, beta7-integrin and CXCR4.
