Working toward immune tolerance in lung transplantation.
Long-term allograft survival is a major challenge facing solid organ transplantation. Recent studies have shown a negative correlation between infiltration of memory T cells and allograft survival. Furthermore, blockade of leukocyte activation increases acceptance of transplanted organs, including heart, liver, and kidney. Lung allografts are associated with high rates of rejection, and therapi...
متن کاملIntestinal tolerance requires gut homing and expansion of FoxP3+ regulatory T cells in the lamina propria.
Tolerance to food antigen manifests in the absence and/or suppression of antigen-specific immune responses locally in the gut but also systemically, a phenomenon known as oral tolerance. Oral tolerance is thought to originate in the gut-draining lymph nodes, which support the generation of FoxP3(+) regulatory T (Treg) cells. Here we use several mouse models to show that Treg cells, after their ...
متن کاملAttitudes toward women and tolerance for sexual harassment among reservists.
Women are more likely to experience sexual harassment in some work settings than others; specifically, work settings that have a large proportion of male workers, include a predominance of male supervisors, and represent traditional male occupations may be places in which there is greater tolerance for sexual harassment. The focus of the study was to document attitudes toward women among milita...
متن کاملEngineering Sugar Utilization and Microbial Tolerance toward Lignocellulose Conversion
Production of fuels and chemicals through a fermentation-based manufacturing process that uses renewable feedstock such as lignocellulosic biomass is a desirable alternative to petrochemicals. Although it is still in its infancy, synthetic biology offers great potential to overcome the challenges associated with lignocellulose conversion. In this review, we will summarize the identification and...
متن کاملToward High-Performance Distributed Stream Processing via Approximate Fault Tolerance
Fault tolerance is critical for distributed stream processing systems, yet achieving error-free fault tolerance often incurs substantial performance overhead. We present AF-Stream, a distributed stream processing system that addresses the trade-off between performance and accuracy in fault tolerance. AF-Stream builds on a notion called approximate fault tolerance, whose idea is to mitigate back...
