We show that the reconstitution capacity of transferred isolated naïve CD8+ T cells and their differentiation of effector functions is limited, but both dramatically increase upon the co-transfer of CD4+ T cells.
To test the survival and proliferative capacity of transferred donor cells, the recipient mice were challenged 8 days after transfer with vv i.p. and their PELs were examined for Thy1.2+ donor-derived pentamer+ cells 3 days after viral challenge.
Moreover, lack of accumulation of splenic CD8α+ DCs later in the infection correlated to reduced capacity of transferred adult CD8 T cells to accumulate in old recipients.
More recently, several data indicated an exosomes-mediated transfer of miRNA between T cells and antigen presenting cells during antigen recognition and a capacity of transferred miRNAs to regulate gene expression in recipient cells, during immune synapse formation [ 73, 82].
T-cell infiltration into tumors was attainable by systemic T-cell delivery, showing the capacity of transferred T cells to circulate, home to the tumor and perform antitumor functions.
"There are no findings," a summary of the report reads, "that would warrant a reduction in the number and capacity of transfer stations in the study area".
To overcome poor infection efficiency and other defects, we used the lentiviral vector as a delivery tool for siRNAs to silence genes, which had advantages in the large capacity of transfer gene fragment, a long time expression of target gene and little immune response.
EMPs display paracrine and autocrine actions on vascular cells, and growing evidence suggests EMPs act as mediators in intracellular signalling because of their capacity to transfer a number of bioactive molecules to recipient cells.
We measured the functional capacity of adoptively transferred CTL clones to produce IFN-γ in response to in vitro antigen after T cell infusion.
While this has been shown in vitro, this example would be the first demonstration that corticosteroids can modulate the functional capacity of adoptively transferred human effector T cell clones in vivo, underlining the importance of evaluating both numeric and functional persistence when tracking T cells in vivo for efficacy and toxicity.
