“…Bivalves have been widely used as sentinel organisms in the biomonitoring of aquatic pollution (7). Pollution may result in the death of haemocytes owing to lysis and in changes in the proportions of their main cell types; this fact had been observed in mussels, oysters and clams (155,348,378). Moreover, the formation of granulocytomas is an inflammatory cellular response associated with environmental pollution.…”

Bivalve molluscs stand out for their ecological success and their key role in the functioning of aquatic ecosystems, while also constituting a very valuable commercial resource. Both ecological success and production of bivalves depend on their effective immune defence function, in which haemocytes play a central role acting as both the undertaker of the cellular immunity and supplier of the humoral immunity. Bivalves have different types of haemocytes, which perform different functions. Hence, identification of cell subpopulations and their functional characterisation in immune responses is essential to fully understand the immune system in bivalves. Nowadays, there is not a unified nomenclature that applies to all bivalves. Characterisation of bivalve haemocyte subpopulations is often combined with 1) other multiple parameter assays to determine differences between cell types in immune-related physiological activities, such as phagocytosis, oxidative stress and apoptosis; and 2) immune response to different stressors such as pathogens, temperature, acidification and pollution. This review summarises the major and most recent findings in classification and functional characterisation of the main haemocyte types of bivalve molluscs.

“…To evaluate the condition of the DG of the M. kurilensis, besides a qualitative analysis to determine the severity of pathological abnormalities, a quantitative analysis was performed on eight parameters that are commonly used in biomonitoring and assessing pathological abnormalities [32,41,[57][58][59][60][61][62][63][64][65]. It was observed that the Coccomyxa invasion in M. kurilensis led to an increase in the infiltration of hemocytes and fibrillar tissue into the interstitial space of the DG, which resulted in the formation of granulocytomas and fibromas.…”

The invasion of bivalves by parasitic microalgae Coccomyxa is widespread and causes pathologies and dysfunctions of the organs, especially in the most valuable products: the mantle and the muscle. The pathogenesis of the disease remains completely unknown. In this study, based on a macroscopic examination of Modiolus kurilensis and microalgae count in each infected individual, four stages of disease development with characteristic pathognomonic symptoms were described. During the progression of the disease, the concentration of alkaline phosphatase, glucose, calcium, hemolytic and agglutinating activities, number of basophils, eosinophils, phagocytes, and cells with reactive oxygen species increased in the hemolymph, while number of agranulocytes, cells with lysosomes, dead hemocytes, total protein concentration, as well as the weight of mollusks decreased. In the nephridia and digestive gland, necrosis, invasion of Nematopsis sp., hemocyte infiltration, and fibrosis increased. The ratio of changed tubules and occurrence of granulocytomas increased in the digestive gland, while the base membrane, nephrocytes and concretions changed in the nephridia. This study helps establish the variability of these parameters under normal conditions and their alteration during the disease. Moreover, these findings can be used for veterinary monitoring of the state of bivalves in natural and aquaculture populations.

“…The species-specificity of invertebrate immune cell morphology includes the species-specificity of cell behavior on the substrate. The differences in cell behavior are based on the differences in functional dynamics of cells, in particular, responses to peculiarities of the external environment (Mermelstein, Rebello, Amaral, and Costa, 2003;Paine, Christensen, Toews, and Simon, 1994), extracellular matrix (Dolatshahi-Pirouz et al, 2011;Vignaud et al, 2012), and genetic, biochemical, and physiological features of cells (Borges et al, 2011;Chauhan, Lou, Zheng, and Lang, 2011), including the cytoskeleton structure (Welsh and Saleem, 2012) and the qualitative and quantitative composition of cell adhesion molecules (Domínguez-Giménez, Brown, and Martin-Bermudo, 2007). The cell activity analysis evaluates interspecies differences cell immunity functioning.…”

Behavioral dynamics of coelomocytes from echinoderms Asterias amurensis and Lysastrosoma anthosticta during the first hour of in vitro cultivation was analyzed using a wide range of linear and fractal parameters of the external morphology. Most of the parameters, including values of the cell bounding circle and convex hull, asymmetry, fractal dimensions of contour images, lacunarity, and cell density and area, showed species-specific behavior of the immune cells of the studied animals. The cells differed in a wide range of parameters as early as two min after seeding on the substrate. The cells acquired the largest morphological differences by the fifth min of cultivation. Both cell dynamics in general and analysis of the cell morphology at individual points in time may serve as markers for species-specificity of cells. However, when morphology is compared at one point in time, at least two parameters associated with significant morphological differences in cells of the studied species should be used because of overlapping tendencies in changes in morphological features.
