Development of techniques to culture shrimp haemocytes and purify white spot syndrome virus (WSSV) in order to study WSSV-haemocyte interactions
The knowledge on immunity of farmed crustaceans is still at an early developmental stage when compared to that of terrestrial livestock. There are many fundamental questions that still need to be answered and others are currently under academic debate. In contrast, the shrimp farming industry has …

An analysis of the cellular and humoral immune responses of Galleria mellonella larvae
… abundance of immune proteins from haemolymph and haemocytes, increased circulating haemocytes, altered expression of genes and a change in the composition of haemocyte populations. These changes peaked 24h after the stress event but declined 72h after the stress event, demonstrating the short term …

The development of Galleria mellonella as a model to test the toxicity of food additives
… was established. The fungicidal ability of haemocytes form larvae administered commonly used food additives was ascertained. There were significant decreases seen in the fungicidal ability of haemocytes extracted from larvae administered sodium benzoate, sodium nitrate, potassium nitrate, …

Investigation of the effect of a probiotic-supplemented diet on the haemocyte proteome of the abalone Haliotis midae
… vary significantly in their expression levels in haemocytes sampled from abalone fed the probiotic-supplemented diet were identified as COP9 signalosome subunit 4, phosphorylase, T-complex protein 1 subunit gamma, V-type proton ATPase subunit B, Rab 1 and Ra-related protein Rab 1A. Differential …

The role of the cytochrome B and cytochrome C oxidase III genes in the immune response of the South African abalone, Haliotis midae
… in a cDNA microarray experiment performed on haemocytes from immunestimulated abalone (Arendze-Bailey, unpublished). The current study sought to confirm these results by semi-quantitative PCR and to further elucidate the roles of these genes, and thus the electron transport system, in the …

An analysis of the interaction of environmental and clinical isolates of Aspergillus fumigatus with vertebrate and invertebrate immune responses
… on human neutrophils and G. mellonella haemocytes. Fumagillin inhibited phagocytosis and pathogen directed killing in both cell types and disrupted oxygen consumption through reduced translocation of p47phox and its insect homologue. Exposure of neutrophils and haemocytes to fumagillin …

A proteomic investigation of the heat stress response of the South African abalone haliotis midae
… proteins that are differentially regulated in haemocytes during exposure to acute heat stress. Identifying which biochemical pathways are involved in the abalone stress response will give some insight into the molecular mechanism by which H. midae responds to heat stress.

A proteomic and cytological characterisation of the buff-tailed bumblebee (Bombus terrestris) fat body and haemolymph -An immune perspective
… and plasmatocytes were the most frequently found haemocytes in bumblebee haemolymph. The FB and haemolymph were also investigated under various stresses and contexts. In general, typical immune responses to microbial challenge were observed although immune signatures were lower than expected. …

Midaesin - a histone H2A antimicrobial peptide from the South African abalone, Haliotis midae
… of total cDNA isolated from cultured H. midae haemocytes exposed to heat-killed V. anguillarum for 1h showed that the histone H2A transcript was upregulated, implying a role in the immune response. A PCR-amplified DNA fragment coding for the Midaesin peptide was cloned into a bacterial …

Ricerca, mediante tecniche di proteomica, di biomarcatori proteici utili nella valutazione della qualità degli alimenti di origine animale
… on cells involved in the immune defence (haemocytes) and on some important enzymatic systems involved in xenobiotic biotransformation processes (cytochrome P450 complex) and in the related antioxidant defence processes (Superoxide dismutase, Catalase, Heat Shock Protein), from a …

Ulva as a functional feed: a practical investigation into the effects of Ulva lacinulata on the growth, consumption, health and gut microbiota of the farmed abalone Haliotis midae
… had more pronounced activity from stimulated haemocytes. Feeding fresh Ulva, as a partial replacement (40%) for a formulated feed, significantly improved SGR and MISL compared to that of abalone fed on either diet individually. Abalone that were fed fresh Ulva had significantly lower muscle …

Investigation of the effect of ocean acidification on the haemocyte proteome of the South African abalone, Haliotis midae
… investigate the proteomic response of H. midae haemocytes to reduced pH conditions representative of future predictions of ocean acidification. Four independent iTRAQ experiments were conducted where haemocytes were sampled after 12, 72 and 168 hours of exposure of H. midae to OA conditions (pH …

Potamanautes warreni biomarker assays to monitor silver nanomaterial contaminants in aquatic environments
… i.e. CYP450, has functional significance in the haemocytes, (7) P. perlatus has proved to be a significant target for AgNP exposure and, furthermore, has proved to be a suitable species to assess the ecotoxicity of AgNP in the aquatic environment, (8) antioxidant enzymes activities (are valuable …

Σηματοδοτικοί μηχανισμοί κατά την απόπτωση και την κυτταροφαγία στα αιμοκύτταρα της μύγας της Μεσογείου
Ο προγραμματισμένος κυτταρικός θάνατος είναι μία θεμελιώδης διαδικασία τόσο για την ανάπτυξη όσο και για την άμυνα και διατήρηση της δομής και της οργάνωσης όλων των πολυκύτταρων οργανισμών. Τα αιμοκύτταρα της μύγας της Μεσογείου υφίστανται απόπτωση με φυσιολογικούς μηχανισμούς κατά την μεταμόρφωση …
