Distinct Costimulatory Molecules Are Required for the Induction of Effector and Memory Cytotoxic T Lymphocytes

A successful T cell immune response has two major products: effector T cells which directly or indirectly remove the antigens, and memory T cells, which allow a faster and more efficient recall response when challenged by related antigens. An important issue is whether costimulatory molecules on the antigen-presenting cells are involved in determining whether T cells will differentiate into eff...

Optimal induction of effector but not memory antitumor cytotoxic T lymphocytes involves direct antigen presentation by the tumor cells.

MHC class I-restricted tumor antigen can be presented to CD8+ T cells by two distinct mechanisms. Direct presentation involves degradation of cytosolic proteins by the proteosome into peptides, transport of the peptides across the endoplasmic reticulum membrane, and expression of the MHC-peptide complex on the tumor cell surface. Cross-presentation, on the other hand, involves uptake and intrac...

Antigen Is Required for the Activation of Effector Activities, whereas Interleukin 2 Is Required for the Maintenance of Memory in Ovalbumin-specific, CD8+ Cytotoxic T Lymphocytes

The mechanisms that maintain memory in T cells are not completely understood. We have investigated the role of antigen and interleukin (IL)-2 in the growth and maintenance of CD8+ T cells using a cytolytic T cell line specific for ovalbumin (OVA)257-264 presented by H-2Kb. This line does not secrete IL-4 or IL-2; hence, stimulation with the OVA-transfected EL4 line (E.G7-OVA) does not induce pr...

Glycosylation of native MHC class Ia molecules is required for recognition by allogeneic cytotoxic T lymphocytes.

The question whether or not target cell N-linked carbohydrate participates in cytotoxic T lymphocyte (CTL) mediated cytolysis has been in contention for well over a decade. Much of the evidence supporting a role for N-linked carbohydrate stems from the treatment of target cells with the glycosylation inhibitor tunicamycin (TM). In this report, we show that treatment of targets with TM, but not ...

Effector memory T lymphocytes in renal disease.

RECENT STUDIES HAVE DEMONSTRATED that the immune system plays an important pathophysiological role in diseases of the kidney and the vasculature. In particular, the role of T lymphocytes in the development and maintenance of renal (1, 3, 4, 5) and cardiovascular disease (3, 5, 6, 9) has been a topic of intense study in recent years. Pharmacological and genetic methods in experimental animals ha...
