Background: Because of high morbidity of the brucellosis in humans and the potential use of the microorganism as an agent of biologic warfare, protection of effective vaccines and specific diagnostic reagents become necessary to eradicate brucellosis. Objective: In this study we aimed to investigate the cytokine responses and changes in peripheral blood lymphocyte subgroups of acute brucellosis...

This study investigates the potential of the alpha CD3-induced killer cells for use in adoptive immunotherapy of tumor growth. The alpha CD3-induced, activated, killer cells (CD3-AK) were generated in DBA/2 (H-2d) splenocytes by preactivation with alpha CD3 and were then cultured in the presence (CD3-AK [alpha CD3+]) or absence (CD3-AK [alpha CD3-]) of alpha CD3. The conventional lymphokine-act...

Background: Regulatory T cells have been suggested to have a protective role against acute rejection in allograft recipients. However, there is little information available about their contribution to chronic rejection process. The role of transforming growth factor-beta 1 (TGF- β1) as a profibrogenic and/or immunoregulatory cytokine in renal allografts is also controversial. Objectives: To eva...
