Although interaction between programmed death-1 (PD-1) and the ligand PD-L1 has been shown to mediate CD8 cell exhaustion in the setting of chronic infection or the absence of CD4 help, a role for this pathway in attenuating early alloreactive CD8 cell responses has not been identified. We demonstrate that the PD-1/PD-L1 pathway is needed to rapidly tolerize alloreactive CD8 cells in a model that requires CD4 cells and culminates in CD8 cell deletion. This protocol involves
Caring for someone with dementia can be demanding, particularly for spouses living with the care recipient. The main goal of this study was to clarify differences in the experience of caregivers who were husbands and wives with respect to burden, health, healthy behaviors, presence of difficult care recipient behaviors, social supports, and the quality of the premorbid relationship. The results of this study support research demonstrating a difference between the caregiving experiences of women and men. It is becoming increasingly apparent that female gender is a marker that places them at increased risk of high burden and less support.
These results are consistent with those of other researchers that use mindfulness-based cognitive therapy to reduce symptoms of depression and suggest that further work to replicate these findings and improve upon the efficacy of the intervention is warranted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
