Residual ß-cells found at the time of clinical onset of type 1 diabetes are sufficient to control hyperglycemia if rescued from ongoing autoimmune destruction. The challenge, however, is to develop an immunotherapy that not only selectively suppresses the diabetogenic response and efficiently reverses diabetes, but also establishes long-term ß-cell-specific tolerance ...

'The ability to quantify and characterize antigen-specific CD8+ T cells irrespective of functional readouts using fluorochrome-conjugated peptide-major histocompatibility complex class I (pMHCI) tetramers in conjunction with flow cytometry has transformed our understanding of cellular immune responses over the past decade. In the case of prevalent CD8+ T cell populations that ... More
The survival of memory CD8 T cells that is mediated by IL-15 correlates with sustained protection against malaria.

'Ag-specific memory T cell responses elicited by infections or vaccinations are inextricably linked to long-lasting protective immunity. Studies of protective immunity among residents of malaria endemic areas indicate that memory responses to Plasmodium Ags are not adequately developed or maintained, as people who survive episodes of childhood malaria are still ...

Role of NK cells in host defense against pulmonary type A Francisella tularensis infection.
'Pneumonic tularemia is a potentially fatal disease caused by the Category A bioterrorism agent Francisella tularensis. Understanding the pulmonary immune response to this bacterium is necessary for developing effective vaccines and therapeutics. In this study, characterization of immune cell populations in the lungs of mice infected with the type A ... More
Measles virus vaccine attenuation: suboptimal infection of lymphatic tissue and tropism alteration.
'The mechanisms of measles virus (MV) vaccine attenuation are insufficiently characterized. Because the Edmonston vaccine strain can enter cells through CD46 in addition to the primary MV receptor signaling lymphocyte activation molecule (SLAM or CD150), we asked whether and how its tropism is altered. In human tonsillar tissue, this vaccine ... More
