Specific T cell immunity in patients with active tuberculosis is associated with a decrease in multifunctionality. However, it is unknown whether cytokine profiles differ in patients with primary infection and those with prior contact. We therefore used intravesical immunotherapy with attenuated live Bacille Calmette-Guérin (BCG) in patients with urothelial carcinoma as a model to characterise ...

we developed an immunogen to stimulate multivalent immunity against hepatitis b surface antigen (hbsag) and hepatitis b core antigens (hbcag). immune responses specific for both hbsag and hbcag play an important role in controlling the infection. hbsag-specific antibodies mediate elimination of virions at an early stage of infection and prevent the spread of virus. the immunogen was constructed...
