H174 is a new member of the CXC-chemokine family. A cDNA probe containing the entire H174 coding region recognized a predominant inducible transcript of approximately 1.5 kb expressed in interferon (IFN) activated astrocytoma and monocytic cell lines. H174 message can be induced following IFN-alpha, IFN-beta, or IFN-gamma stimulation. H174 message was also detected in IFN treated cultures of primary human astrocytes, but was absent in unstimulated astrocytes. H174, like IP10 and Mig, lacks the ELR sequence associated with the neutrophil specificity characteristic of most CXC-chemokines. Preliminary experiments suggest H174, IP10 and Mig are independently regulated. Recombinant H174 is a weak chemoattractant for monocyte-like cells. H174 can also stimulate calcium flux responses. The data support the classification of H174 as a member of a subfamily of interferon-gamma inducible non-ELR CXC-chemokines. Brain tissues were obtained at autopsy from one patient with AIDS dementia, one patient with multiple sclerosis, and two normal control patients. H174 and Mig were detected by RT-PCR in brain tissue cDNA derived from the patients with pathological conditions associated with activated astrocytes but not in cDNA from control specimens.
This research output has an Altmetric Attention Score of 3. 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 17 July 2010.
All research outputs
#12,425,845
of 34,518,147 outputs
Outputs from Journal of NeuroVirology
#384
of 1,161 outputs
Outputs of similar age
#37,456
of 132,715 outputs
Outputs of similar age from Journal of NeuroVirology
#8
of 24 outputs
Altmetric has tracked 34,518,147 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,161 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.3. This one is in the 47th percentile – i.e., 47% 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 132,715 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 24 others from the same source and published within six weeks on either side of this one. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
