We recently reported the elevation of inflammatory cytokines in the aqueous humor (AqH) in eyes with bullous keratopathy and low ECD. To evaluate the association between ECD and aqueous cytokine levels, we collected a total of 157 AqH samples prospectively. The AqH levels of cytokines were measured and multivariate analyses were conducted to find the correlation between ECD, aqueous cytokine levels and clinical factors, such as number of previous intraocular surgeries and protein concentration in AqH. As a result, ECD was negatively correlated with specific cytokine levels, including IL-1\u03b1, IL-4, IL-13, MIP-1\u03b2, TNF-\u03b1 and E-selectin (all P\u2009&lt;\u20090.05). The aqueous cytokine levels showed different correlations with these clinical factors; the number of previous intraocular surgeries was associated with all cytokines except MIP-1\u03b1. The AqH protein concentration and the status of intraocular lens showed similar patterns of elevation of IL-1\u03b1, IL-4, IL-6, IL-8, IL-10, IL-13, IL-17A, MIP-1\u03b2, MCP-1, E-selectin, P-selectin and sICAM-1. In conclusion, elevation of AqH cytokine levels was associated with reduced ECDs. AqH cytokine levels showed significant correlations with clinical factors associated with low ECDs.<\/jats:p>","DOI":"10.1038\/s41598-017-14131-3","type":"journal-article","created":{"date-parts":[[2017,10,13]],"date-time":"2017-10-13T15:00:12Z","timestamp":1507906812000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":47,"title":["Association between corneal endothelial cell densities and elevated cytokine levels in the aqueous humor"],"prefix":"10.1038","volume":"7","author":[{"given":"Yukari","family":"Yagi-Yaguchi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takefumi","family":"Yamaguchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazunari","family":"Higa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Terumasa","family":"Suzuki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naohiko","family":"Aketa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Murat","family":"Dogru","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiyuki","family":"Satake","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Shimazaki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2017,10,19]]},"reference":[{"key":"14131_CR1","doi-asserted-by":"publisher","first-page":"27","DOI":"10.1016\/0014-4835(88)90021-8","volume":"47","author":"KH Carlson","year":"1988","unstructured":"Carlson, K.
