| Abstract |
The adoptive transfer of alternatively activated macrophages (AAMs) has proven to attenuate inflammation in multiple mouse models of colitis, however the effect of cryopreservation on AAMs, the ability of previously frozen AAMs to block DNBS (Th1) and oxazolone (Th2) colitis, and their migration post-injection remains unknown. Here we have found that while cryopreservation reduced mRNA expression of canonical markers of IL-4-treated macrophages [M(IL-4)], this did not translate to reduced protein or activity and the cells retained their capacity to drive the suppression of colitis. The anti-colitic effect of M(Il-4) adoptive transfer required neither T or B cell nor peritoneal macrophages in the recipient. Following injection into the peritoneal cavity, M(IL-4s) migrated to the spleen, MLNs and colon of DNBS-treated mice. The chemokines CCL2, CCL4, and CX3CL1 were expressed in the colon during the course of DNBS-induced colitis. The expression of integrin β7 on transferred M(IL-4)s was required for their anti-colitic effect, while the presence of the chemokine receptors CCR2 and CX3CR1 were dispensable in this model. Collectively the data show that M(IL-4)s can be cryopreserved M(IL-4)s and subsequently used to suppress colitis in an integrin β7-dependent manner and we suggest that these proof-of-concept studies may lead to need cellular therapies for human inflammatory bowel disease. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 25 December 2015.
All research outputs
#20,299,108
of 22,836,570 outputs
Outputs from Molecular Medicine
#1,000
of 1,139 outputs
Outputs of similar age
#326,292
of 389,036 outputs
Outputs of similar age from Molecular Medicine
#20
of 27 outputs
Altmetric has tracked 22,836,570 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,139 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.2. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 389,036 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 27 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
