Initiation of Innate Immune Responses in the Freshwater Crayfish Pacifastacus leniusculus

open access: yes, 2001
Prophenoloxidase (proPO) is a key enzyme for generation of melanin and is activated by the proPO activating enzyme (ppA) to its active form, PO. The active ppA was purified and cloned from crayfish hemocytes and it is a typical serine proteinase containing a clip, a proline-rich, and a glycine-rich domain.

Melanization and Hemocyte Homeostasis  in the Freshwater Crayfish, Pacifastacus leniusculus

open access: yes, 2013
Blood cells or hemocytes play important roles in immunity. They are a major source of many immune-related molecules such as antibodies in adaptive immunity of vertebrates and prophenoloxidase (proPO) in invertebrates. In the crayfish Pacifastacus leniusculus, the proPO-system has been reported to be an important component of immune responses against ...

The effects of astakine on the hemocyte differentiation in Pacifastacus leniusculus

open access: yes
Crayfish use their native immune system to avoid infections. They produce new stem cells and blood cells (hemocytes) continuously throughout their lifetimes. The hemocytes are produced by stem cells in the hematopoietic tissue and released into the circulation.

Melanization and pathogenicity in Tenebrio molitor and Pacifastacus leniusculus by Aeromonas hydrophila.

open access: yes, 2010
Aeromonas hydrophila is the most common Aeromonas species causing infections in human and other animals such as amphibians, reptiles, fish and crustaceans. Pathogenesis of Aeromonas species have been reported to be associated with virulence factors such as lipopolysaccharides (LPS), bacterial toxins, bacterial secretion systems, flagella, and other ...
