CTLA4Ig and anti-LFA-1 are members of a new generation of immunomodulatory drugs which inhibit important signaling pathways in T cell activation. Both substances target molecules which have pivitol...

Heterologous immunity provides a potent barrier to transplantation tolerance

Adams, Andrew B., Williams, Matthew A., Jones, Thomas R., Shirasugi, Nozomu, Durham, Megan M., Kaech, Susan M., ...

Many strategies have been proposed to induce tolerance to transplanted tissue in rodents; however, few if any have shown equal efficacy when tested in nonhuman primate transplant models. We...

Intravital microscopy identifies selectins that regulate T cell traffic into allografts

Jones, Thomas R., Shirasugi, Nozomu, Adams, Andrew B., Pearson, Thomas C., Larsen, Christian P.

T cell homing to sites of injury and inflammation is a critical step for adaptive immune responses. While much has been learned regarding T cell homing to lymphoid tissues, few studies have directly...

Blockade of T cell costimulation reveals interrelated actions of CD4+ and CD8+ T cells in control of SIV replication

Garber, David A., Silvestri, Guido, Barry, Ashley P., Fedanov, Andrew, Kozyr, Natalia, McClure, Harold, ...

In vivo blockade of CD28 and CD40 T cell costimulation pathways during acute simian immunodeficiency virus (SIV) infection of rhesus macaques was performed to assess the relative contributions of...

Asialo GM1+ CD8+ T cells play a critical role in costimulation blockade–resistant allograft rejection

Trambley, Joel, Bingaman, Adam W., Lin, Angello, Elwood, Eric T., Waitze, Seung-Yeun, Ha, Jongwon, ...

Simultaneous blockade of the CD40 and CD28 costimulatory pathways is an effective treatment strategy to promote allograft acceptance but does not lead to indefinite allograft survival. The immune...

SVR angiosarcomas can be rejected by CD4 costimulation dependent and CD8 costimulation independent pathways.

Arbiser, Jack L., Bingaman, Adam, Durham, Megan, Cowan, Shannon, Cohen, Cynthia, Zarnegar, Elham, ...
