The results demonstrated that stimulation of animals with TAP and MHC-I proficient tumor cells generated antigen specific T cells with greater killing activities than those of TAP and MHC-I deficient tumor cells.
Next, we performed in vitro and in vivo experiments to determine whether the TAP and MHC-I proficient CMT.TAP1,2/Kb was able to induce tumor-antigen specific immunity.
This discrepancy was traced to differences in the ability of dendritic cells (DCs) to access and sample different antigen reservoirs in TAP and MHC-I proficient versus deficient cells and thereby stimulate adaptive immune responses through the process of cross-presentation.
A conflicting report exists from Huang et al [15] who used the MHC-I negative B78H1 and its MHC-I proficient transfectant (derived from B16 melanoma) as a model system to immunize mice and then challenged with MHC-I positive B78H1 cells.
These results provide an explanation why immunization with MHC-I proficient (CMT.TAP1,2/Kb) cells can increase the generation and production of T cells resulting in immune responses greater than those adaptive T cell responses generated by immunization with MHC-I deficient (CMT.64) cells.
While I spoke English, I still had a lot to learn before I became proficient.
I am proficient in several programming languages, and I can pick up a new one very quickly.
Once I become proficient enough to impart my knowledge to others I would possibly like to come back to city life and apply for grants and work with organizations like "Big City Mountaineers" to take metropolitan youth on trips to mountainous wilderness areas.
Every morning I study a chapter in 'iPhone for Dummies,' and now I'm proficient.
Is she proficient at "classroom management?" Are all the sheep with the herd?
