THREATS OF ARSENIC ON MORPHOLOGICAL SHIFT OF HEMOCYTES OF MOLLUSCS: A HINT TOWARDS ARSENIC-INDUCED CELL DEATH
SRIKANTA GURIA
Abstract:
Immune system is strongly influenced by environmental conditions. Arsenic is an important environmental pollutant. Due to high distribution worldwide, the molluscs accumulate large amount of pollutants, which is responsible for immune challenge. Cellular response in molluscs is carried out by hemocytes that can kill microbes through phagocytosis and cytotoxic reactions. In the present study significant changes were observed in the cytomorphology of hemocytes of aquatic molluscs (Pila sp.) upon treatment with arsenic. Treated cells showed different phases of cellular death like formation of membrane blebs, rupture of plasma membrane. Small cytoplasmic vacuoles were found in arsenic (As) treated hemocytes. This report has suggested nature of cell death may be used as an effective biomarker of aquatic pollution. Hemocytes thus serve as a unique tool for the testing of the toxicity of environmental pollutant.Hemocytes will help to establish an effective bio-indicator which may provide good systems to evaluate the toxic effects of environmental contaminants.
