Synthesis, secretion, transport and accumulation of four particular proteins, representative members of four characteristic groups, were followed during metamorphosis by immunoblot and immuncytochemical methods and are described in detail in this paper. We established that only some of the proteins of the soft cuticle of Lepidopteran larvae are synthesized in epidermal cells at the beginning of the larval stages and are digested during the moulting period (MsCP29). Other proteins (MsCP30\/11) are secreted into the cuticle by the epidermal cells in different forms during various developmental stages. Some proteins are secreted apically during the feeding period, but before ecdysis they are then taken up by epidermal cells and transported in a basolateral direction back into the hemolymph and saved in an immunologically intact form by the fat body cells (MsCP12.3). Some cuticle proteins have a non-epidermal origin. They are transported from the hemolymph into the cuticle. Before and during ecdysis these molecules reappear in the hemolymph and are detectable again in the pupal cuticle (MsCP78). Our data prove that the cuticle is not a non-living part of the insect body: it is not only an inert, protective armor, but maintains a continuous and dynamic metabolic connection with the other organs of the organism.<\/jats:p>","DOI":"10.1242\/jcs.112.13.2113","type":"journal-article","created":{"date-parts":[[2021,4,25]],"date-time":"2021-04-25T17:17:48Z","timestamp":1619371068000},"page":"2113-2124","source":"Crossref","is-referenced-by-count":42,"title":["Insect cuticle, an in vivo model of protein trafficking"],"prefix":"10.1242","volume":"112","author":[{"given":"Gy\u00f6rgy","family":"Csik\u00f3s","sequence":"first","affiliation":[{"name":"E\u00f6tv\u00f6s Lor\u00e1nd University, Budapest Department of General Zoology , , 1088 Puskin u. 3, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kinga","family":"Moln\u00e1r","sequence":"additional","affiliation":[{"name":"E\u00f6tv\u00f6s Lor\u00e1nd University, Budapest Department of General Zoology , , 1088 Puskin u. 3, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"No\u00e9mi H.","family":"Borhegyi","sequence":"additional","affiliation":[{"name":"E\u00f6tv\u00f6s Lor\u00e1nd University, Budapest Department of General Zoology , , 1088 Puskin u. 3, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G\u00e1bor Cs.","family":"Tali\u00e1n","sequence":"additional","affiliation":[{"name":"E\u00f6tv\u00f6s Lor\u00e1nd University, Budapest Department of General Zoology , , 1088 Puskin u. 3, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mikl\u00f3s","family":"Sass","sequence":"additional","affiliation":[{"name":"E\u00f6tv\u00f6s Lor\u00e1nd University, Budapest Department of General Zoology , , 1088 Puskin u. 3, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"237","published-online":{"date-parts":[[1999,7,1]]},"reference":[{"key":"2024011300020584000_JOCES_112_13_2113C1","doi-asserted-by":"publisher","first-page":"177","DOI":"10.1016\/0965-1748(94)00048-M","article-title":"Comparison of larval and pupal cuticular proteins in Tenebrio molitor","volume":"25","author":"Anderson","year":"1995","journal-title":"Insect Biochem.
