Negative co-receptors on lymphocytes.

Abstract:

:The past year has seen significant advances in our understanding of critical roles of negative immunoregulatory signals delivered through the B7-CD28 superfamily in regulating T cell activation and tolerance. Structural data on CTLA-4 have provided novel insights into the inhibitory functions of CTLA-4. Initial characterization of the PD-1-PD-1-ligand pathway has revealed that this pathway can downregulate TCR- and CD28-mediated signals. Recent studies indicate that ICOS exerts distinct effects at different phases of an immune response: ICOS can inhibit as well as stimulate T cell responses.

  • Regulation of immunological memory.

    abstract::Immunological memory can be regulated during either its development or its maintenance phases. Controversy and confusion surround both methods of regulation, especially in the field of T-cell memory. Recent work has helped in improving our definition of 'a memory cell', but this has been complicated by another major p...
