Dear colleagues and friends,

we currently are in the midst of the arrangements for our next International Meeting, which will be held from March 14 – 16 in Munich. We are very happy that Prof. Heinrich Leonhardt from the LMU Munich agreed to join us as the local meeting president and to bring our International Meeting to one of the brightest hotspots for cell biological re- search in Europe. The venue will be at the biomedical center of the brand new university campus in Martinsried.

Meanwhile, we have some tradition in inviting societies from our neighboring countries to showcase their cell biological research. Like this year, when the Dutch Society for Cell Biology was our guest during the International Meeting in Cologne, we have invited the Austrian Association of Molecular Life Sciences and Biotechnology (ÖGMBT) to join next year’s meeting in Martinsried. Thus, Prof. Lukas Huber (University of Innsbruck) joined Heinrich Leonhardt and his organization team comprising Prof. Reinhard Fässler (MPI), PD Dr. Annette Müller-Taubenberger (LMU), and the DGZ executive committee. Moreover, we have implemented additional innovations: First of all, the Meeting will be shorter. Perso- nal communication with many members and our exhibitors, who are the most important sponsors of our meeting, suggested a more compact format. The Munich meeting will be held on three days with three plenary sessions and eight symposia covering the hottest topics in cell biology (see page 5 for the full list of topics). Moreover, sessions will be co- chaired by two scientists from Austria and . In order to make the meeting more attractive to young scientists, symposia will have three slots for short talks selected from the abstracts instead of only two, and there will be an additional slot for very short flash talks, which may be used for “poster advertisements”. Thus, the stage is set for a lively and exciting meeting. Save the date, we would love to meet you there!

Cell biological research is an international issue. Thus, the executive committee has de- cided to follow the invitation to join the International Federation of Cell Biology (IFCB). The mission of the IFCB is to "promote international cooperation, and to contribute to the advancement of cell biology in all its branches" (wp.ifcbiol.org/). Membership is free of charge for our society. The IFCB organizes a very interesting meeting July 21 – 25 next year in (www.iccb2016.org/), and has already announced a discount of 50€ for members of all IFCB societies including the DGZ.

Last but not least I would again like to encourage you to send articles for Cell News! Copyrights will remain completely yours and it is a wonderful chance to advertise your research to the cell biology community. To this end, you will find more information at zellbiologie.de/cellnews/for-authors/

Many regards,

Ralph Gräf (President)

Proteins folded to their final conformation are shipped to the Golgi apparatus and the plasma membrane through vesicular transport (4). If chaperone- assisted protein folding fails (5), misfolded proteins trigger the endoplasmic reticulum’s unfolded protein response (UPRER), which in turn induces the expression of chaperones. Misfolded proteins can be shuttled to the cytoplasm via the ER-associated degradation (ERAD) machinery to become substrates for proteasomal or autophagic degradation. However, an overload of unfolded proteins can lead to toxic protein aggregation. GlcNAc Mannose Glucose

Figure 2: Hexosamine pathway flux affects protein homeostasis and longevity. The hexosamine biosynthetic pathway (HP) shunts a fraction of fructose-6-phosphate into the synthesis of the activated amino sugar UDP-N-acetylglucosamine (UDP-GlcNAc). UDP-GlcNAc serves as a building block for N- and O-Glycan structures, can be added to proteins as a single moiety, and is also a component of biopolymers such as chitin or glycosaminoglycans (GAGs). Activating the HP through gain-of-function mutation of the rate-limiting enzyme glutamine-fructose-6-phosphate aminotransferase (GFAT-1) or by supplementing N-acetylglucosamine (GlcNAc) induces protein quality control mechanisms (proteasome activity, ER-associated degradation (ERAD), and autophagy), resulting in increased lifespan and reduced proteotoxicity in the nematode C. elegans. In mammals, the ER unfolded protein response (UPRER) was shown to directly induce GFAT-1 expression, which exerts cardioprotective effects through increased O-GlcNAcylation.
