“…In O. dofleini and Sepia officinalis, this has been confirmed by successful isolation of hemocyanin-specific mRNA from branchial gland preparations ). In addition, Beuerlein et al (1998) identified ovoid cells of the branchial heart as the site of hemocyanin catabolism in Sepia. On the other hand, in Nautilus pompilius hemocyanin is apparently synthesized in the hepatopancreas (Ruth et al 1988(Ruth et al , 1996, and Ruth et al (2000) reported that the four pericardial appendages of Nautilus are also involved in hemocyanin metabolism.…”

Rhogocytes (pore cells) are specific molluscan cell types that are scattered throughout the connective tissues of diverse body parts. We have identified rhogocytes in large numbers in tissue taken from mantle, foot and midgut gland of the abalone Haliotis tuberculata (Vetigastropoda). Within cisternae of the endoplasmic reticulum, particles are visible that resemble, in shape and size, hemocyanin molecules, the respiratory protein of many molluscs. Immunohistochemical experiments using hemocyanin-specific antibodies demonstrated that these cells contain hemocyanin. In situ hybridization with a cDNA probe specific for Haliotis hemocyanin showed that hemocyanin-specific mRNA is present in rhogocytes, which confirmed that they are the site of hemocyanin biosynthesis in this gastropod. A possible path of hemocyanin release into the hemolymph is discussed. Also in the vetigastropod Megathura crenulata, many rhogocytes could be detected. However, they lacked hemocyanin molecules which, together with published data, indicates a seasonal expression of hemocyanin in this animal.

“…Cephalopods are considered “advanced” invertebrates and the only class to possess, among mollusks, a close circulatory system with one systemic, and two accessory hearts. The branchial hearts are involved in the production of hemocyanin (Schipp, 1987 ; Wells and Smith, 1987 ; Beuerlein et al, 1998 , 2002 ). Cephalopods have an innate immune system similarly to other mollusks; their immune defense is mediated by activation of cellular factors as antibacterial peptides, whereas the immune system works on the basis of “cellular factors” (Troncone et al, 2014 ; Castillo et al, 2015 ).…”

Under a continuous changing environment, animals are challenged with stresses and stimuli which demanding adaptation at behavioral and physiological levels. The adaptation strategies are finely regulated by animal nervous, endocrine, and immune systems. Although it's been established by now the usage of integrative approach to the study the endocrine and nervous systems (neuroendocrine), yet our understanding of how they cooperate with the immune system remains far from complete. The possible role that immune system plays as a component of the network has only been recognized recently. Octopus vulgaris is an important member of cephalopods and is considered as a model species, with considerable information about the neuroendocrine and immune systems. In the current review, we anticipate to shed light on the complexity and cross talk among the three systems and how they cooperate in setting physiological response to stresses-stimuli in O. vulgaris as a target species and primary example.

The knowledge of the organization of normal tissues and the changes occurring during physiological or pathological processes is basic to interpret the relationship between structure and function. There are numerous microscopic studies focused on different cephalopod organs that are based on the use of high-resolution methods as the transmission electron microscopy. However, there is no comprehensive basic histological guide to the different tissues in common species of cephalopods. To fill this gap, we present a careful description of the normal histological organization of cephalopods. Through 35 plates including 225 photomicrographs and the accompanying text descriptions, this chapter covers the body systems of three common species of European coleoid cephalopods, the cuttlefish (Sepia officinalis), the squid (Loligo vulgaris) and the octopus (Octopus vulgaris). The histology of the three species is presented in parallel, emphasizing those significant between-species differences. Sections used for study and photomicrographs were mostly stained with hematoxylin-eosin (H&E), a standard light microscopy method widely accessible for most laboratories of histology and pathology. Some sections of octopus were stained the Masson's trichrome or the periodic acid-Schiff (PAS) methods.
