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
Background and objectives: Excessive adipose tissue macrophage accumulation in obesity has been implicated in mediating inflammatory responses that impair glucose homeostasis and promote insulin resistance. Colony-stimulating factor 1 (CSF1) controls macrophage differentiation, and here we sought to determine the effect of a CSF1 receptor inhibitor, PLX3397, on adipose tissue macrophage levels and understand the impact on glucose homeostasis in mice. Methods: A Ten-week-old mice were fed a chow or high-fat diet for 10 weeks and then treated with PLX3397 via oral gavage (50 mg/kg) every second day for 3 weeks, with subsequent monitoring of glucose tolerance, insulin sensitivity and assessment of adipose tissue immune cells. Results: PLX3397 treatment substantially reduced macrophage numbers in adipose tissue of both chow and high-fat diet fed mice without affecting total myeloid cell levels. Despite this, PLX3397 did not greatly alter glucose homeostasis, did not affect high-fat diet-induced increases in visceral fat cytokine expression (Il-6 and Tnfa) and had limited effect on the phosphorylation of the stress kinases JNK and ERK and macrophage polarization. Conclusions: Our results indicate that macrophage infiltration of adipose tissue induced by a high-fat diet may not be the trigger for impairments in whole body glucose homeostasis, and that anti-CSF1 therapies are not likely to be useful as treatments for insulin resistance.
