Authors evaluated changes in glycosylation of SFs with using lectins and MS, and confirmed that sialylation decreased in both N-glycans and O-glycans. The decrease in sialylation was observed in \u03b1-3Sia but not \u03b1-3Sia. Furthermore, levels of sialylation correlated with disease stages. And, it was shown that the decrease in sialylation seems to be induced by TNF, in contrast with IL-1 or IL-17 that had no effect.<\/p>\n<p>It is so important to establish whether desialylation plays a leading role in SFs activation, or on the contrary, it is a more indirect consequence of ongoing inflammation. Authors demonstrated that \u03b12-6Sia blocking by ST6GAL1 mRNA silencing upregulates IL-6 and CcL2. This would be a really meaningful thing relating to the therapeutic strategies.<\/p>\n<p>In a figure below, CIA means Collagen-induced arthritis.<br \/>\n<a href=\"https:\/\/www.emukk.com\/WP\/wp-content\/uploads\/2021\/04\/Collagen-induced-arthritis.png\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.emukk.com\/WP\/wp-content\/uploads\/2021\/04\/Collagen-induced-arthritis-300x112.png\" alt=\"\" width=\"300\" height=\"112\" class=\"alignleft size-medium wp-image-3420\" srcset=\"https:\/\/www.emukk.com\/WP\/wp-content\/uploads\/2021\/04\/Collagen-induced-arthritis-300x112.png 300w, https:\/\/www.emukk.com\/WP\/wp-content\/uploads\/2021\/04\/Collagen-induced-arthritis-600x225.png 600w, https:\/\/www.emukk.com\/WP\/wp-content\/uploads\/2021\/04\/Collagen-induced-arthritis-768x288.png 768w, https:\/\/www.emukk.com\/WP\/wp-content\/uploads\/2021\/04\/Collagen-induced-arthritis.png 892w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A group from University of Glasgow, UK, etc. has reported a detailed studies on the relationship between glyco<\/p><\/div>\n<div class=\"blog-btn\"><a href=\"https:\/\/www.emukk.com\/WP\/en\/interesting-relationship-between-glycosylation-of-synovial-fibroblasts-and-arthritis-inflammation\/\" class=\"home-blog-btn\">\u7d9a\u304d\u3092\u8aad\u3080<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[70],"tags":[],"class_list":["post-3427","post","type-post","status-publish","format-standard","hentry","category-nature-en"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.emukk.com\/WP\/wp-json\/wp\/v2\/posts\/3427","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.emukk.com\/WP\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.emukk.com\/WP\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.emukk.com\/WP\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.emukk.com\/WP\/wp-json\/wp\/v2\/comments?post=3427"}],"version-history":[{"count":3,"href":"https:\/\/www.emukk.com\/WP\/wp-json\/wp\/v2\/posts\/3427\/revisions"}],"predecessor-version":[{"id":3430,"href":"https:\/\/www.emukk.com\/WP\/wp-json\/wp\/v2\/posts\/3427\/revisions\/3430"}],"wp:attachment":[{"href":"https:\/\/www.emukk.com\/WP\/wp-json\/wp\/v2\/media?parent=3427"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.emukk.com\/WP\/wp-json\/wp\/v2\/categories?post=3427"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.emukk.com\/WP\/wp-json\/wp\/v2\/tags?post=3427"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
