Effects of autophagy inhibition by 3-methyladenine on encystation, morphology, and metabolites of Cryptocaryon irritans

Encystment is crucial for defense and reproduction in Cryptocaryon irritans. Therefore, understanding the encystment-related events in the protomont stage can help prevent and control C. irritans. Autophagy promotes protozoan parasite encystation. However, 3MA can inhibit autophagy. In this study, t...

520			\|a Encystment is crucial for defense and reproduction in Cryptocaryon irritans. Therefore, understanding the encystment-related events in the protomont stage can help prevent and control C. irritans. Autophagy promotes protozoan parasite encystation. However, 3MA can inhibit autophagy. In this study, the effects of autophagy inhibition on encystation, survival rate, ultrastructural features, and metabolomic profiles of C. irritans, were evaluated using protomonts treated with 3MA (20 mM). The treatment with 3MA for about 4 h significantly lowered survival and encystation rates of protomonts to about 86.44% and 76.08%, respectively. Microstructural observations showed that the 3MA-treated protomonts showed deformed cell membranes and the cytoplasmic content spill. Furthermore, observation of the ultrastructure of 3MA-treated protomonts showed the destruction of organelles (Golgi bodies and mucocyst) and a lack of autophagosomes. However, no abnormality was observed in the control experiments. Furthermore, the metabolic analysis revealed suppression of metabolites, such as lipids, amino acids, and carbohydrates. These results demonstrate that 3MA can inhibit autophagy in C. irritans, thus hindering encystation, suppressing the metabolism of metabolites, and altering morphological ultrastructure in these parasites.

Encystment is crucial for defense and reproduction in Cryptocaryon irritans. Therefore, understanding the encystment-related events in the protomont stage can help prevent and control C. irritans. Autophagy promotes protozoan parasite encystation. However, 3MA can inhibit autophagy. In this study, the effects of autophagy inhibition on encystation, survival rate, ultrastructural features, and metabolomic profiles of C. irritans, were evaluated using protomonts treated with 3MA (20 mM). The treatment with 3MA for about 4 h significantly lowered survival and encystation rates of protomonts to about 86.44% and 76.08%, respectively. Microstructural observations showed that the 3MA-treated protomonts showed deformed cell membranes and the cytoplasmic content spill. Furthermore, observation of the ultrastructure of 3MA-treated protomonts showed the destruction of organelles (Golgi bodies and mucocyst) and a lack of autophagosomes. However, no abnormality was observed in the control experiments. Furthermore, the metabolic analysis revealed suppression of metabolites, such as lipids, amino acids, and carbohydrates. These results demonstrate that 3MA can inhibit autophagy in C. irritans, thus hindering encystation, suppressing the metabolism of metabolites, and altering morphological ultrastructure in these parasites.

Therefore, understanding the encystment-related events in the protomont stage can help prevent and control C. irritans. Autophagy promotes protozoan parasite encystation. However, 3MA can inhibit autophagy. In this study, the effects of autophagy inhibition on encystation, survival rate, ultrastructural features, and metabolomic profiles of C. irritans, were evaluated using protomonts treated with 3MA (20 mM). The treatment with 3MA for about 4 h significantly lowered survival and encystation rates of protomonts to about 86.44% and 76.08%, respectively. Microstructural observations showed that the 3MA-treated protomonts showed deformed cell membranes and the cytoplasmic content spill. Furthermore, observation of the ultrastructure of 3MA-treated protomonts showed the destruction of organelles (Golgi bodies and mucocyst) and a lack of autophagosomes. However, no abnormality was observed in the control experiments. Furthermore, the metabolic analysis revealed suppression of metabolites, such as lipids, amino acids, and carbohydrates. These results demonstrate that 3MA can inhibit autophagy in C. irritans, thus hindering encystation, suppressing the metabolism of metabolites, and altering morphological ultrastructure in these parasites.

abstract	Encystment is crucial for defense and reproduction in Cryptocaryon irritans. Therefore, understanding the encystment-related events in the protomont stage can help prevent and control C. irritans. Autophagy promotes protozoan parasite encystation. However, 3MA can inhibit autophagy. In this study, the effects of autophagy inhibition on encystation, survival rate, ultrastructural features, and metabolomic profiles of C. irritans, were evaluated using protomonts treated with 3MA (20 mM). The treatment with 3MA for about 4 h significantly lowered survival and encystation rates of protomonts to about 86.44% and 76.08%, respectively. Microstructural observations showed that the 3MA-treated protomonts showed deformed cell membranes and the cytoplasmic content spill. Furthermore, observation of the ultrastructure of 3MA-treated protomonts showed the destruction of organelles (Golgi bodies and mucocyst) and a lack of autophagosomes. However, no abnormality was observed in the control experiments. Furthermore, the metabolic analysis revealed suppression of metabolites, such as lipids, amino acids, and carbohydrates. These results demonstrate that 3MA can inhibit autophagy in C. irritans, thus hindering encystation, suppressing the metabolism of metabolites, and altering morphological ultrastructure in these parasites.
