Analysis of primary T cell responses to intact and fractionated microbial pathogens

Abstract:
Freshly isolated human T lymphocytes were tested for their response to mycobacteria, mycobacterial lysates, 2 dimensional (2D) PAGE separated mycobacterial lysates, leishmania and defined leishmanial antigen preparations. While gamma delta T cells proliferated vigorously in the presence of mycobacteria and mycobacteria derived lysates, a significant stimulation from 2 D gel separated lysates was not detected. In addition gamma delta T cells failed to respond towards leishmania or leishmanial components. In the alpha beta T cell compartment some donors, presumably according to their state of immunity against mycobacteria, responded to mycobacteria, mycobacterial lysates and 2 D gel separated mycobacterial lysates. Neither freshly isolated gamma delta T cells nor alpha beta T cells from naive donors did mount a significant immune response against leishmania.

T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...
