Dynamics of Lymphocyte Reconstitution After Hematopoietic Transplantation During Chronic Lymphocytic Choriomeningitis Virus Infection.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Bone marrow transplantation is a treatment for various cancers and genetic diseases, and the only case of a cured HIV infection involved the use of this clinical procedure, highlighting the potential use of this therapy for curing many chronic diseases. However, little is known about how chronic viral infection influences lymphocyte reconstitution after bone marrow transplantation. To address this, we infected mice with chronic lymphocytic choriomeningitis virus, and performed bone marrow transplantation to assess lymphocyte reconstitution. Interestingly, we observed that adoptively transferred marrow cells exhibited preferential B cell differentiation in chronically infected mice. Moreover, donor marrow cells that were adoptively transferred into chronically infected mice differentiated into virus-specific CD8 T cells that were able to expand after PD-L1 blockade. Taken together, our data show that chronic viral infection induces a biased differentiation of bone marrow stem cells into B cells, and that exhausted virus-specific CD8 T cells generated de novo in this setting are rescuable by PD-1 blockade. These data contribute to the understanding of how chronic viral infection impacts lymphocyte reconstitution, and may provide valuable information to improve current hematopoietic transplantation regimens in chronically infected hosts.
