Annelid neuroimmune system.
Neuropeptides have been found in nervous central or immune systems of Annelids. Since these signaling molecules are found free in the hemolymph, they are considered as hormones. Hormonal processes along with enzymatic processing similar to that found in vertebrates occur in annelids. Furthermore, amino acid sequence determination of annelids precursor gene products reveals the presence of the r...
متن کاملMolecular Aspect of Annelid Neuroendocrine system
Hormonal processes along with enzymatic processing similar to that found in vertebrates occur in annelids. Amino acid sequence determination of annelids precursor gene products reveals the presence of the respective peptides that exhibit high sequence identity to their mammalian counterparts. Furthermore, these neuropeptides exert similar physiological function in annelids than the ones found i...
متن کاملThe structure of annelid and mollusc hemoglobins.
The polypeptide chain composition and the chemical properties of several annelid hemoglobins and chlorocruorins are presented. In agreement with earlier studies on the hemoglobin from Arenicola cristata (Waxman, L. (1971) J. Biol. Chem. 246, 7318-7327), nearly all of the pigments which have been examined consist of one or more different disulfide-linked polypeptide chains of 13,000 to 16,000 da...
متن کاملArtificial annelid robot driven by soft actuators.
The annelid provides a biological solution of effective locomotion adaptable to a large variety of unstructured environmental conditions. The undulated locomotion of the segmented body in the annelid is characterized by the combination of individual motion of the muscles distributed along the body, which has been of keen interest in biomimetic investigation. In this paper, we present an annelid...
