Spatio-temporal expression of Mesocestoides corti McVAL2 during strobilar development

Area of Science:

• Parasitology
• Molecular Biology
• Biochemistry

Background:

• VAL proteins, part of the CAP superfamily, are found in eukaryotes and involved in host-parasite interactions.
• These secreted proteins are potential vaccine candidates against nematode infections.
• Their function in cestodes, like M. corti, remains largely uncharacterized.

Purpose of the Study:

• To characterize the expression of McVAL2 in M. corti larvae and segmented worms.
• To investigate mRNA and protein localization using fluorescent microscopy.
• To optimize real-time PCR for quantifying McVAL2 mRNA expression across developmental stages.

Main Methods:

• Fluorescent microscopy for mRNA and protein localization.
• Real-time PCR for mRNA expression quantification.
• Analysis of McVAL2 expression in M. corti larvae and segmented worms.

Main Results:

• McVAL2 exhibits differential localization dependent on the developmental stage.
• McVAL2 serves as a molecular marker for the neuroendocrine system in M. corti larvae.
• Dynamic and stage-specific expression patterns were observed for McVAL2.

Conclusions:

• The VAL protein family likely plays diverse roles in the biology of parasitic flatworms.
• McVAL2's stage-specific expression highlights its potential involvement in parasite development and host interaction.
• Further research into VAL proteins could reveal new targets for controlling parasitic flatworm infections.
