Gene expression of Pocillopora damicornis coral larvae in response to acidification and ocean warming

Objectives The endosymbiosis with Symbiodiniaceae is key to the ecological success of reef-building corals. However, climate change is threatening to destabilize this symbiosis on a global scale. Most studies looking into the response of corals to heat str ...

Automated flow control of a multi-lane swimming chamber for small fishes indicates species-specific sensitivity to experimental protocols

In fishes, swimming performance is considered an important metric to measure fitness, dispersal and migratory abilities. The swimming performance of individual larval fishes is often integrated into models to make inferences on how environmental parameters ...

Self-organized patterning of cell morphology via mechanosensitive feedback

Marko Popovic

Tissue organization is often characterized by specific patterns of cell morphology. How such patterns emerge in developing tissues is a fundamental open question. Here, we investigate the emergence of tissue-scale patterns of cell shape and mechanical tiss ...

PDMS filter structures for size-dependent larval sorting and on-chip egg extraction of C. elegans

Martinus Gijs, Hüseyin Baris Atakan, Furkan Ayhan

C. elegans-based assays require age-synchronized populations prior to experimentation to achieve standardized sets of worm populations, due to which age-induced heterogeneous phenotyping effects can be avoided. There have been several approaches to synchro ...

Hookworms Evade Host Immunity by Secreting a Deoxyribonuclease to Degrade Neutrophil Extracellular Traps

Arne Seitz, Romain Guiet, Nicola Harris, Beatrice Volpe, Tiffany Babette Angélique Bouchery, Kathleen Shah, Mati André Marie Moyat, Manuel Kulagin

Hookworms cause a major neglected tropical disease, occurring after larvae penetrate the host skin. Neutrophils are phagocytes that kill large pathogens by releasing neutrophil extracellular traps (NETs), but whether they target hookworms during skin infec ...

Device and method for sorting biological entities

Francesco Mondada, Frank Bonnet, Norbert Crot, Marcin Antoni Sylwestrzak

A device for sorting biological entities is disclosed. The device comprises a channel to canalize the biological entities and a selector having slots to accommodate said entities. Means for detecting and analysing an optical parameter of the biological ent ...

Microfluidic and micromechanical in vivo studies of Caenorhabditis elegans

Roger Philippe Krenger

Caenorhabditis elegans is one of the most attractive model organisms in biomedical research for understanding human diseases and for drug testing at a whole-organism level, since many biological pathways and genes have been conserved between itself and hum ...

Remodeling of peripheral nerve ensheathment during the larval-to-adult transition in Drosophila

Soumya Banerjee, Kumar Vishal

Over the course of a 4-day period of metamorphosis, the Drosophila larval nervous system is remodeled to prepare for adult-specific behaviors. One example is the reorganization of peripheral nerves in the abdomen, where five pairs of abdominal nerves (A4-A ...

dHb9 Expressing Larval Motor Neurons Persist Through Metamorphosis to Innervate Adult-Specific Muscle Targets and Function in Drosophila Eclosion

Soumya Banerjee

The Drosophila larval nervous system is radically restructured during metamorphosis to produce adult specific neural circuits and behaviors. Genesis of new neurons, death of larval neurons and remodeling of those neurons that persistent collectively act to ...

Two Conserved Histone Demethylases Regulate Mitochondrial Stress-Induced Longevity

Johan Auwerx, Laurent Mouchiroud, Evan Graehl Williams, Virginija Jovaisaite

Across eukaryotic species, mild mitochondrial stress can have beneficial effects on the lifespan of organisms. Mitochondrial dysfunction activates an unfolded protein response (UPR(mt)), a stress signaling mechanism designed to ensure mitochondrial homeost ...

Versatile size-dependent sorting of C-elegans nematodes and embryos using a tunable microfluidic filter structure

Martinus Gijs, Thomas Lehnert, Matteo Cornaglia, Li Dong

The roundworm Caenorhabditis elegans (C. elegans) is a powerful model organism for addressing fundamental biological questions related to human disease and aging. Its life cycle consists of an embryo stage, four larval stages that can be clearly distinguis ...

Multimodal stimulus coding by a gustatory sensory neuron in Drosophila larvae

Philippe Renaud

Accurate perception of taste information is crucial for animal survival. In adult Drosophila, gustatory receptor neurons (GRNs) perceive chemical stimuli of one specific gustatory modality associated with a stereotyped behavioural response, such as aversio ...

From Embryo to Adult: Hematopoiesis along the Drosophila Life Cycle

Bruno Lemaitre, Elodie Julie Virginie Ramond

Studies on Drosophila hematopoiesis have thus far focused on the embryonic and larval origin of hemocytes, the fly blood cells. In this issue of Developmental Cell, Ghosh et al. (2015) identify adult hematopoietic hubs containing progenitors that can diffe ...
