SUMMARY The tumor necrosis factor receptor family member 4-1BB plays a key role in the survival of activated and memory CD8(+) T cells. Depending on the disease model, 4-1BB can participate at different stages and influence different aspects of the immune response, likely due to the differential expression of receptor and ligand relative to other(More)
A critical issue during severe respiratory infection is whether it is the virus or the host response that does the most damage. In this study, we show that endogenous 4-1BBL plays a critical role in protecting mice from severe effects of influenza disease. During mild respiratory influenza infection in which virus is rapidly cleared, the inducible(More)
The regulation of T cell expansion by TNFR family members plays an important role in determining the magnitude of the immune response to pathogens. As several members of the TNFR family, including glucocorticoid-induced TNFR-related protein (GITR), are found on both regulatory and effector T cells, there is much interest in understanding how their effects(More)
GITR [glucocorticoid inducible tumor necrosis factor receptor (TNFR)-related protein] and 4-1BB are costimulatory TNFR family members that are expressed on regulatory and effector T cells as well as on other cells of the immune system. Here we discuss the role of GITR and 4-1BB on T cells during viral infections and in cancer immunotherapy. Systemic(More)
T cell based influenza vaccines offer the potential for cross protective immunity to multiple clades of influenza virus. Here we explored the effect of increasing CD8 T cell responses during intranasal vaccination by incorporating a T cell costimulator, 4-1BBL. Inclusion of 4-1BBL in an influenza nucleoprotein (NP)-containing adenoviral vector increased the(More)
Immunity to viruses must be tightly controlled to avoid pathology. Receptors and ligands of the tumor necrosis factor (TNF) family play important roles in controlling lymphocyte activation and survival during an immune response. The role of specific TNF receptor (TNFR) family members in antiviral immunity depends on the stage of the immune response and can(More)
PURPOSE The purpose of this study was to characterize the natural history of meibomian gland morphogenesis in the mouse. METHODS Embryonic (E) and post natal (P) C57Bl/6 mouse pups were obtained at E18.5, P0, P1, P3, P5, P8, P15, and P60. Eyelids were fixed and processed for en bloc staining with Phalloidin/DAPI to identify gland morphogenesis, or frozen(More)
The ability to mount a strong immune response against pathogens is crucial for mammalian survival. However, excessive and uncontrolled immune reactions can lead to autoimmunity. Unraveling how the reactive versus tolerogenic state is controlled might point toward novel therapeutic strategies to treat autoimmune diseases. The surface receptor Toso/Faim3 has(More)
Obesity-related insulin resistance is associated with an influx of pathogenic T cells into visceral adipose tissue (VAT), but the mechanisms regulating lymphocyte balance in such tissues are unknown. Here we describe an important role for the immune cytotoxic effector molecule perforin in regulating this process. Perforin-deficient mice (Prf1(null)) show(More)
The signaling adaptor TNFR-associated factor 1 (TRAF1) is specifically lost from virus-specific CD8 T cells during the chronic phase of infection with HIV in humans or lymphocytic choriomeningitis virus (LCMV) clone 13 in mice. In contrast, TRAF1 is maintained at higher levels in virus-specific T cells of HIV controllers or after acute LCMV infection. TRAF1(More)
