1. Crustacean immunity : Characterization of some crayfish blood proteins
Sammanfattning : The cDNA sequence and some properties of a previously purified #x03B2;-1,3-glucan binding protein are reported here. The putative amino acid sequence (predicted molecular mass: 152 kDa) of the protein did not show any significant similarity to any known protein, but an RGD motif and a region with slight similarity to bacterial glucanase was found.

2. Differentiation and Pathogenicity within the Saprolegniaceae : Studies on Physiology and Gene Expression Patterns in Saprolegnia parasitica and Aphanomyces astaci
Sammanfattning : Saprolegnia parasitica and Aphanomyces astaci are parasitic water moulds belonging to the Oomycetes. Despite their importance as parasites they are very little studied at the molecular level and the work described in this thesis was aimed at increasing the molecular knowledge of these organisms by cloning and characterising genes of potential importance for reproduction and pathogenicity.

3. Characterisation of some iron proteins in Drosophilia melanogaster and Pacifastacus leniusculus
Sammanfattning : The cDNA cloning of the 76-kDa protein, an immune protein from crayfishhaemocytes, shows that it is similar to a family of haem-containing peroxidases.In addition to its cell adhesion activity it has also peroxidase activity, and theprotein was named peroxinectin. The cell adhesion is probably mediated by aKGD-motif present in peroxinectin. LÄS MER
4. Initiation of Innate Immune Responses in the Freshwater Crayfish Pacifastacus leniusculus
Sammanfattning : 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. LÄS MER
5. Characterisation of Some Immune Genes in the Black Tiger Shrimp, Penaeus monodon
Sammanfattning : The molecular mechanisms of the immune system in shrimp, Penaeus monodon, are completely unknown, despite its economic importance as an aquaculture species, especially in Asia and Latin America. The genes and their gene products involved in the prophenoloxidase activating system, which is considered to be a non-self recognition and defence system in many invertebrates, have been isolated and characterised in shrimp.
