Co-option of immune and digestive cellular machinery to support photosymbiosis in amoebocytes of the upside-down jellyfish Cassiopea xamachana
ABSTRACTThe upside-down jellyfish Cassiopea spp. host their algal symbionts inside a subset of amoebocytes, phagocytic cells that also play innate immune functions akin to macrophages from vertebrate animals. Amoebocyte precursors phagocytose alga...

Extracellular and intracellular digestion in bivalves, studied by magnetic resonance imaging with a contrast reagent
ABSTRACTWe investigated extracellular and intracellular digestion in bivalves, employing magnetic resonance imaging (MRI). Ruditapes philippinarum clams and Mytilus galloprovincialis mussels were incubated in seawater containing a contrast reagent...

Dynamic reciprocal morphological changes in insect hosts and bacterial symbionts
ABSTRACTSymbiotic interactions, central to most life on Earth, are interwoven associations that vary in intimacy and duration. Some of the most well-known examples of symbioses occur between animals and gut bacteria. These associations lead to phy...

Evolutionary insights into gut acidification: invertebrate-like mechanisms in the basal vertebrate hagfish
ABSTRACTAcidification is a key component of digestion throughout metazoans. The gut digestive fluid of many invertebrates is acidified by the vesicular-type H+-ATPase (VHA). In contrast, vertebrates generate acidic gut fluids using the gastric H+/...

Accounting for the role of the gastro-intestinal tract in the ammonia and urea nitrogen dynamics of freshwater rainbow trout on long-term satiation feeding
ABSTRACTThe contribution of the gut to the ingestion, production, absorption and excretion of the extra ammonia and urea nitrogen (urea-N) associated with feeding (‘exogenous’ fraction) has received limited attention. Analysis of commercial pellet...
