Because the control of HIV-1 replication is largely dependent on CD8+ T lymphocyte responses specific for immunodominant viral epitopes, vaccine strategies that increase the breadth of dominant epitope-specific responses should contribute to containing HIV-1 spread. Developing strategies to elicit such broad immune responses will require an understanding of the mechanisms responsible for focusi...

CONTEXT Mixed lymphocyte culturing has led to conflicting opinions regarding the selection of donors for bone marrow transplantation. The association between a positive mixed lymphocyte culture and the development of graft-versus-host disease (GVHD) is unclear. The use of exogenous cytokines in mixed lymphocyte cultures could be an alternative for increasing the sensitivity of culture tests. ...

The role of specific cell-mediated immune responses in human cytomegalovirus (CMV) infections was studied by an in vitro lymphocyte transformation test, using a whole blood culture. CMV-induced in vitro lymphocyte proliferation was mainly dependent on the presence of sensitized T-cells. Three of five seronegative patients with B-cell deficiency showed positive lymphocyte responses to CMV antige...

purpose: evaluation of humoral and cellular immune responses of naturally infected dogs against type i (rcpb) (recombinant cycsteine proteinase b), and ii (rcpa) (recombinant cycsteine proteinase a) recombinant cysteine proteinases and c-terminal extension (cte) of leishmania infantum (l. infantum). materials and methods: in this study, fourteen infected dogs (7 with symptoms, 7 asymptomatics)...

The role of cell interactions in lymphocyte stimulation was analyzed by studying the kinetics of lymphocyte proliferation at different cell concentrations, and also by a lymphocyte microculture technique in solid medium. An absolute requirement for cell interactions was found in lymphocyte responses to concanavalin A, pokeweed mitogen, sodium periodate, purified protein derivative from Mycobact...

Background: Vaccines capable of controlling tumor virus based infections are found difficult to develop due to the consistence latent infection in the host. DNA vaccines are attractive tools for the development of HPV vaccines and inducing antigen-specific immunity owing to the stability, simplicity of delivery, safety and cost effectiveness. However, there is a need to increase their potency b...
