Evidence for the involvement of interleukin-1α during development of experimental cytomegalovirus retinitis in immunosuppressed mice.
Article in Cytokine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Interleukin-1α (IL-1α) is an alarmin involved in the recruitment of macrophages and neutrophils during tissue inflammation. IL-1α can undergo cleavage by proteases, such as calpain-1, that enhances IL-1α binding to its receptor, although proteolytic cleavage is not necessary for biological activity. Macrophages and neutrophils are involved in the retinal inflammation associated with development of AIDS-related human cytomegalovirus (HCMV) retinitis. We therefore performed studies to test the hypothesis that IL-1α gene expression is stimulated intraocularly during retinitis development using two mouse models of murine cytomegalovirus (MCMV) retinitis that differ in method of immunosuppression, one by retrovirus-induced immunosuppression (MAIDS) and the other by corticosteroid-induced immunosuppression. MCMV-infected eyes of groups of retinitis-susceptible mice with MAIDS of 10 weeks duration (MAIDS-10 mice) and retinitis-susceptible corticosteroid-treated mice showed significant stimulation of IL-1α mRNA. Western blot analysis confirmed IL-1α protein production within the MCMV-infected eyes of MAIDS-10 mice. Whereas significant intraocular calpain-1 mRNA and protein production were also observed within MCMV-infected eyes of MAIDS-10 mice, the MCMV-infected eyes of retinitis-susceptible corticosteroid-treated mice showed a pattern of mRNA synthesis equivalent to that found within the MCMV-infected eyes of healthy mice that fail to develop retinitis. Our findings suggest a role for the alarmin IL-1α in the pathogenesis of MCMV retinitis in immunosuppressed mice. These findings may extend to the pathogenesis of HCMV retinitis in patients with AIDS or other forms of immunosuppression.
