TÜMRI majaseminarid 2023. aasta kevadel
TÜ molekulaar- ja rakubioloogia instituudi majaseminarides tutvustatakse põhjalikumalt instituudi erinevate töörühmade teadusuuringuid. Seminarid on avatud kõigile huvilistele ja loomulikult on oodatud lisaks TÜMRI ja naaberinstituutide teadustöötajatele ka kõikide õppeastmete tudengid.
Seminaride toimumise aeg on üle ühe nädala neljapäeviti kell 15.00 Omicumi maja auditooriumis 105 (Riia 23b/2, Tartu). Seminaride töökeel on inglise keel. Ettekande pikkus 35-45 minutit. Küsimustele ja diskussioonile on arvestatud lisaks 15 minutit. Peale seminari ametliku aja lõppu on kõigil kuulajatel võimalus ettekandjale vabamas õhkkonnas veel küsimusi esitada. Seminare veebis üle ei kanta ega salvestata.
Tulevased seminarid:

Seminari teema: „Interplanar Amida Network: An intercellular network supporting 3D morphogenesis
Ingliskeelne kokkuvõte: Comprehensive analysis of cellular dynamics is fundamental to animal development during the process of morphogenesis. Despite recent advancements in light microscopy, how successive cell shape changes lead to 3D morphogenesis has yet to be fully understood. In this study, we used in vivo live imaging of Drosophila wing development to investigate unique cellular structures comprising a membrane protrusion network: the Interplanar Amida Network (IPAN). The IPAN initially sustains cell-cell contacts between two wing epithelia through basal protrusions. The subsequent programmed disassembly of the IPAN involves the loss of these contacts, which are required for tissue proliferation both autonomously and non-autonomously. Furthermore, intercellular trafficking via membrane protrusions provides a unique framework for tissue morphogenesis. In this talk, I will discuss our ongoing projects and future plans.

Seminari teema: „Metabolic programming by predator (psychological) stress"
Ingliskeelne kokkuvõte: Predator stress is a chronic form of stress elicitated by constant presence of predators. The biochemical and behavioral changes caused by predator stress are very similar to human psychological disorders such as anxiety and depression. By characterizing alterations induced by predator stress in Drosophila, we have discovered that diabetes-like reprogramming of metabolism, involving inactivation of Akt kinase and signaling by serotonin. We report the first direct evidence how depression-like states can cause metabolic deficiency in animals and provide explanation for such (mal)adaptive changes.
