Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Dendritic cells (DCs) consist of heterogeneous phenotypic populations and have diverse immunostimulatory functions dependent on both lineage and functional phenotype, but as exceptionally potent antigen-presenting cells, they are targets for generating effective antigen-specific immune responses. A promising replicon particle vector derived from Venezuelan equine encephalitis virus (VEE) has been reported to transduce murine footpad DCs. However, the receptive DC subset, the degree of restriction for this tropism, and the extent of conservation between rodents and humans have not been well characterized. Using fresh peripheral blood DCs, mononuclear cells, monocyte-derived macrophages, and monocyte-derived DCs, our results demonstrate conservation of VEE replicon particle (VRP) tropism for DCs between humans and rodents. We observed that a subset of immature myeloid DCs is the target population, and that VRP-transduced immature DCs retain intact functional capacity, for example, the ability to resist the cytopathic effects of VRP transduction and the capacity to acquire the mature phenotype. These studies support the demonstration of selective VRP tropism for human DCs and provide further insight into the biology of the VRP vector, its parent virus, and human DCs. © Mary Ann Liebert, Inc.
