Investigating the effect of starvation and various nutritional types on the hemocytic profile and phenoloxidase activity in the Indian meal moth Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae)

Invertebrate Survival Journal, 2020
The defense mechanisms of the insects are based on involvement of the hemocytes and phenoloxidase. Hemocytes are the basic component of the cellular immunity and phenoloxidase as the part of prophenoloxidase (PPO) cascade is the component of both humoral

Purification and characterization of phenoloxidase from the hemolymph of Hyphantria cunea (Lepidoptera: Arctiidae)

Invertebrate Survival Journal, 2012
Phenoloxidase (PO) is a key factor in insect immunity. On invasion of microorganisms and pathogens, prophenoloxidase changes to its active form to PO.

[Different faces of phenoloxidase in animals].

Postepy biochemii, 2019
Phenoloxidases are oxidoreducting enzymes whose main function is the oxidation of phenols. The term phenoloxidase is often used interchangeably to describe three different enzymes: tyrosinase (EC 1.14.18.1), catechol oxidase, and laccase. Of these, only tyrosinase has two activities: (1) oxygenase activity to hydroxylate monophenols to ortho-diphenols ...

First report of phenoloxidase and peroxidase activities in two intertidal sea anemone species of Argentina

Invertebrate Survival Journal, 2014
The presence of immune responses within sea anemone species has received little attention, in comparison with coral species, so we decided to investigate the phenoloxidase and peroxidase activities in ectoderm, endoderm and tentacles of actiniarians ...
