The Eco-Immunological Relevance of the Anti-Oxidant Response in Invasive Molluscs

open access: yesAntioxidants, 2023
Reactive oxygen species (ROS) are volatile and short-lived molecules playing important roles in several physiological functions, including immunity and physiological adaptation to unsuitable environmental conditions.

Nitric oxide production by Biomphalaria glabrata haemocytes: effects of Schistosoma mansoni ESPs and regulation through the extracellular signal-regulated kinase pathway

open access: yesParasites & Vectors, 2009
Background Schistosoma mansoni uses Biomphalaria glabrata as an intermediate host during its complex life cycle. In the snail, the parasite initially transforms from a miracidium into a mother sporocyst and during this process excretory-secretory ...

ROLE OF POLLEN AND/OR BEE BREAD AVAILABILITY IN BROOD REARING AND CELLULAR IMMUNE SYSTEM OF HONEYBEES [PDF]

open access: yesJournal of Plant Protection and Pathology, 2014
The role of pollen and/or bee bread availability was evaluated on brood rearing, protein content and haemolymph of 6-days-old larvae worker honeybees. The highest area of stored pollen and/or bee bread and worker unsealed brood was recorded during August

Non-cytotoxic hydroxyl-functionalized exfoliated boron nitride nanoflakes impair the immunological function of insect haemocytes in vivo

open access: yesScientific Reports, 2019
To induce the water solubility of hexagonal boron nitride (h-BN), we exfoliated and functionalized bulk h-BN with hydroxyl groups (h-BN-OH-n). Short-term studies showed that h-BN-OH-n induced low cytotoxicity in different models: insect haemocytes (in ...

Types of haemocytes in saprophagous soil mites (Acari: Oribatida, Acaridida), and the correlation between their presence and certain processes within mites

open access: yesEuropean Journal of Entomology, 2006
The microanatomy of several oribatid and one acaridid mite was studied to determine the role of free cells (haemocytes) in mites. Mites from the field as well as laboratory cultures were observed and analyzed histologically using Masson triple stain. The

Drosophila as a model to study the role of blood cells in inflammation, innate immunity and cancer

open access: yesFrontiers in Cellular and Infection Microbiology, 2014
Drosophila has a blood system with three types of haemocytes which function throughout different developmental stages and environmental stimuli. Haemocytes play essential roles in tissue modelling during embryogenesis and morphogenesis, and also in ...

Solanum nigrum Fruit Extract Modulates Immune System Activity of Mealworm Beetle, Tenebrio molitor L.

open access: yesToxins, 2023
Here, we report the first evidence concerning the modulation of insect immune system activity after applying Solanum nigrum fruit extract (EXT). We focused on two main issues: (1) is EXT cytotoxic for Tenebrio molitor haemocytes?

Effects of X-ray irradiation on haemocytes of Procambarus clarkii (Arthropoda: Decapoda) males

open access: yesThe European Zoological Journal, 2018
The red swamp crayfish Procambarus clarkii is an invasive alien species spreading worldwide. The sterile male release technique (SMRT) is among the methods used to contrast the growth of P. clarkii populations within invaded areas.

Evaluation of farnesol-induced changes in the haemocyte pattern of red cotton bug Dysdercus koenigii Fabricius (Heteroptera: Pyrrhocoridae)

open access: yesJournal of Basic and Applied Zoology, 2022
Background Dysdercus koenigii Fabricius is a polyphagous agricultural pest of paramount importance. Farnesol is a plant-derived open-chain aliphatic sesquiterpenoid alcohol. It is an intermediate in the metabolic pathway of juvenile hormone biosynthesis.
