Potential of coelomocyte chemotaxis as an immune biomarker in the earthworm, Lumbricus terrestris.

摘要

Coelomocyte migration responses, both random and chemotatic, were examined in the earthworm Lumbricus terrestris. Coelomocyte random migration patterns towards nonstimulatory, non-chemotatic solutions were described. Migration responses to immunostimulatory agents lipopolysaccharides (LPS), N-formly-methionyl-leucylphenylalanine (FMLP), sheep erythrocytes, Saccharomyces cerevisiae, Aeromonas hydrophila, Eisenia fetida and Rhabditis pellio were characterized. Chemotaxis was reported to LPS, FMLP, sheep erythrocytes, S. cerevisiae and E. fetida. Bio-indicator potential of chemotaxis is discussed relative to variability in migration responses.
