Cortical flows mediate anteroposterior polarization in Caenorhabditis elegans by generating two mutually exclusive membrane domains. However, factors downstream of anteroposterior polarity that establish the dorsoventral axis remain elusive. Here, we show that rotational cortical flow orthogonal to the anteroposterior axis during the division of the AB(More)
At the end of cytokinesis, the dividing cells are connected by an intercellular bridge, containing the midbody along with a single, densely ubiquitylated, circular structure called the midbody ring (MR). Recent studies revealed that the MR serves as a target site for membrane delivery and as a physical barrier between the prospective daughter cells. The MR(More)
Apoptotic cell death and survival is controlled by pro- and antiapoptotic proteins. Because these proteins act on each other, cell fate is dictated by the relative activity of pro- versus antiapoptotic proteins. Here we report that BRUCE, a conserved 528 kDa peripheral membrane protein of the trans-Golgi network, protects cells against apoptosis and(More)
Autophagy can act either as a tumor suppressor or as a survival mechanism for established tumors. To understand how autophagy plays this dual role in cancer, in vivo models are required. By using a highly heterogeneous C. elegans germline tumor, we show that autophagy-related proteins are expressed in a specific subset of tumor cells, neurons. Inhibition of(More)
Cytokinesis involves the formation of a cleavage furrow, followed by abscission, the cutting of the midbody channel, the final bridge between dividing cells. Recently, the midbody ring became known as central for abscission, but its regulation remains enigmatic. Here, we identify BRUCE, a 528 kDa multifunctional protein, which processes(More)
The use of volatile anaesthetics in intensive care medicine has so far been limited by the lack of equipment suitable for daily routine use and the need for an anaesthetic machine. The new Anaesthetic Conserving Device (AnaConDa) enables the routine use of volatile anaesthetics for long-term sedation via intensive care ventilators. The Anaesthetic(More)
Members of the inhibitor of apoptosis protein (IAP) family are key regulators of apoptosis as they bind and inhibit caspases and other pro-apoptotic factors. Recent findings suggest that these proteins play additional roles, e.g., in cell cycle regulation, angiogenesis, and carcinogenesis. Here, we review the function of BRUCE (BIR repeat-containing(More)
BACKGROUND Novel tuberculosis vaccines should be safe, immunogenic, and effective in various population groups, including HIV-infected individuals. In this phase II multi-centre, double-blind, placebo-controlled trial, the safety and immunogenicity of the novel H1/IC31 vaccine, a fusion protein of Ag85B-ESAT-6 (H1) formulated with the adjuvant IC31, was(More)
22 Over the past few decades, many researchers have concluded that adequately addressing issues in the knowledge society requires a major transformation of research, away from disengaged disciplines toward socially engaged, transdisciplinary approaches. To date, knowledge exchange between transdisciplinarity researchers via academic publications has been(More)
