The fish expresses green fluorescent protein together with Interleukin-1 (IL-1), one of the key inflammatory signals in vertebrates.<\/p>\n\n\n\n<p>While IL-1 is expressed all over the tail fin skin, it is located more intensely at the fin\u2019s edge and within its lateral line organs, which form this distinct pattern that can be seen. Using a fluorescent protein and microscopy allows Eva to see where IL-1 is expressed. It also helps her to understand how its expression responds to injury and infection, and how the molecule is processed in the course of inflammation.<\/p>\n\n\n\n<p>Credit: Eva Hasel\/EMBL<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In the Leptin Group, Eva Hasel investigates the innate immune system in Japanese rice fish.<\/p>\n","protected":false},"author":76,"featured_media":23540,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[6,17591],"tags":[1728,531,1313,820,616],"embl_taxonomy":[],"class_list":["post-23534","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-picture-of-the-week","category-science-technology","tag-interleukin","tag-leptin","tag-medaka","tag-picture-of-the-week","tag-protein"],"acf":{"show_featured_image":false,"featured":false,"article_intro":"","article_sources":false,"related_links":false,"in_this_article":false,"color":"#007B53","youtube_url":"","mp4_url":"","video_caption":"","translations":false,"press_contact":"None"},"embl_taxonomy_terms":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.2 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Underwater butterfly | EMBL<\/title>\n<meta name=\"description\" content=\"In the Leptin Group at EMBL Heidelberg, Eva Hasel investigates the innate immune system in Japanese rice fish (also known as medaka).\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.embl.org\/news\/picture-of-the-week\/potw2021\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Underwater butterfly | EMBL\" \/>\n<meta property=\"og:description\" content=\"In the Leptin Group at EMBL Heidelberg, Eva Hasel investigates the innate immune system in Japanese rice fish (also known as medaka).\" \/>\n<meta property=\"og:url\" content=\"https:\/\/www.embl.org\/news\/picture-of-the-week\/potw2021\/\" \/>\n<meta property=\"og:site_name\" content=\"EMBL\" \/>\n<meta property=\"article:publisher\" content=\"https:\/\/www.facebook.com\/embl.org\/\" \/>\n<meta property=\"article:published_time\" content=\"2020-05-26T07:00:00+00:00\" \/>\n<meta property=\"article:modified_time\" content=\"2024-03-22T10:56:41+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/www.embl.org\/news\/wp-content\/uploads\/2020\/04\/potw2021.jpg\" \/>\n\t<meta property=\"og:image:width\" content=\"1000\" \/>\n\t<meta property=\"og:image:height\" content=\"600\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/jpeg\" \/>\n<meta name=\"author\" content=\"Mehdi Khadraoui\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:creator\" content=\"@mehdi_khadra\" \/>\n<meta name=\"twitter:site\" content=\"@embl\" \/>\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"Mehdi Khadraoui\" \/>\n\t<meta name=\"twitter:label2\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data2\" content=\"1 minute\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"NewsArticle\",\"@id\":\"https:\/\/www.embl.org\/news\/picture-of-the-week\/potw2021\/#article\",\"isPartOf\":{\"@id\":\"https:\/\/www.embl.org\/news\/picture-of-the-week\/potw2021\/\"},\"author\":{\"name\":\"Mehdi Khadraoui\",\"@id\":\"https:\/\/www.embl.org\/news\/#\/schema\/person\/87796b717b5c0e0e1e0061f3bbb9b6e0\"},\"headline\":\"Underwater butterfly\",\"datePublished\":\"2020-05-26T07:00:00+00:00\",\"dateModified\":\"2024-03-22T10:56:41+00:00\",\"mainEntityOfPage\":{\"@id\":\"https:\/\/www.embl.org\/news\/picture-of-the-week\/potw2021\/\"},\"wordCount\":150,\"publisher\":{\"@id\":\"https:\/\/www.embl.org\/news\/#organization\"},\"image\":{\"@id\":\"https:\/\/www.embl.org\/news\/picture-of-the-week\/potw2021\/#primaryimage\"},\"thumbnailUrl\":\"https:\/\/www.embl.org\/news\/wp-content\/uploads\/2020\/04\/potw2021.jpg\",\"keywords\":[\"interleukin\",\"leptin\",\"medaka\",\"picture of the week\",\"protein\"],\"articleSection\":[\"Picture of the week\",\"Science &amp;
