Immune defense of Pieris brassicae larvae in challenged with Heterorhabditis bacteriophora, its symbiotic bacteria and metabolites [PDF]
In this study, virulence of the culture broth of Photorhabdus temperata subsp. temperata and its aqueous and organic extracts were investigated for 3rd and 4th instars of Pieris brassicae (Lepidoptera: Pieridae) larvae. Virulent efficacy was found in all

Myriapod haemocyanin: the first three-dimensional reconstruction of Scolopendra subspinipes and preliminary structural analysis of S. viridicornis [PDF]
Haemocyanins (Hcs) are copper-containing, respiratory proteins that occur in the haemolymph of many arthropod species. Here, we report the presence of Hcs in the chilopode Myriapoda, demonstrating that these proteins are more widespread among the ...

Relative phenoloxidase activity in the hemolymph of bacteria-infected insects.
Mean relative phenoloxidase activity per ml of hemolymph of G. mellonella larvae injected with different bacteria or with buffer controls at 4h, 24h, and 48h post-treatment. Absorbance measurements were taken 30 min after hemolymph incubation.

Role and Importance of Phenoloxidase in Insect Hemostasis [PDF]
In response to microbial infection, insects mount several defense reactions including the induction of proteolytic cascades that lead to localized melanization and coagulation. Melanization requires the activation of prophenoloxidase (proPO) to its active form phenoloxidase (PO), a key enzyme that leads to the formation of melanin at wound sites and ...

Reef-building corals face a multitude of threats not only from global climate change but also local stressors such as nutrient pollution. Nutrient enrichment can amplify the negative effects of predation on corals by facilitating dysbiosis in the coral ...

Tarantula Hemocyanin Shows Phenoloxidase Activity [PDF]
An enzyme generally catalyzes one well defined reaction with high specificity and efficiency. We report here in contrast that the copper protein hemocyanin of the tarantula Eurypelma californicum exhibits two different functions. These occur at the same active site.

Hemocyanin-derived phenoloxidase reaction products display anti-infective properties [PDF]
Hemocyanin is a multi-functional protein located in the hemolymph (blood) of certain arthropods and molluscs. In addition to its well-defined role in oxygen transport, hemocyanin can be converted into a phenoloxidase-like enzyme.

Signature miRNAs involved in the innate immunity of invertebrates. [PDF]
The innate immune system, including the cell-based immunity (mainly apoptosis and phagocytosis) and the humoral immunity (such as pro-phenoloxidase system), is the first defense line of animals against the infection of pathogens in a non-specific manner,
