“…Cushing et al [112] demonstrated that the antibacterial activity in the haemolymph of three species of abalone is inducible. Preimmunizing the animals with killed bacteria led to a rapid rise in haemolymph bactericidal activity that peaked in a few days before subsiding after five to eight days.…”

In invertebrates, the innate immune system protects against a wide range of microbiological infections. Several immunological processes are involved in the interactive immune response between snails and their parasites, including phagocytosis, nitric oxide synthesis, phenol oxidase activity, lysozymes, and lectin formation. The immunological responses connected to the interaction between snails and parasites are discussed in detail in the current research. Understanding the nature of these interactive reactions will enable scientists to explore approaches to eliminate and cure parasitic infections.

“…molluscs appears to be relatively rare. To date, there has been only one report of induced bactericidal response in abalones challenged with a formalin-killed suspension of bacterial culture EMB-1 (Cushing et al, 1971). This may be a result of limited knowledge, or these animals may present different immunological strategies.…”

The internal defence system of gastropod molluscs is able to discriminate between self and non-self. The recognition is carried out principally by both the cellular and humoral components of the haemolymph. Together with freely circulating haemocytes, other defence cells are found scattered throughout the tissue or localized in organs. The present review refers primarily to Planorbarius corneus, since the defence mechanisms presented by this animal are typical of those of the other gastropods studied. P. corneus presents two circulating haemocytes: the spreading (SH) and the round haemocytes (RH); in other gastropods only one cell type is described, and this can be considered as a spreading haemocyte. The haemocytes derive both from a haematopoietic organ and from mature circulating haemocytes. The SH show phagocytic properties, adhere to glass, produce agglutinins, bind Con A and contain muramic acid. The RH have non phagocytic properties, do not adhere to glass, form rosettes with sheep red blood cells, are stimulated to proliferate by PHA and present numerous typical markers of vertebrate T lymphocytes. RH are also able to lyse 51 Cr pre-labeled K562 target cells in a classical, short-term, natural cytotoxicity test, and this function is modulated by human recombinant interleukin-2. Furthermore, SH and RH play a role in the recognition of foreign tissue, the SH are able to encapsulate and phagocytize foreign material, and the RH, with their NK (natural killer)-like activity, may act like the vertebrate cytotoxic T lymphocytes or NK cells. Thus, it is possible to conclude that RH have characteristics reminiscent of vertebrate T lymphocytes, while SH belong to the category of macrophages. With regards to the humoral component, different factors, such as lysosomal enzymes, lysins and agglutinins or lectins, have been described. In P. corneus, a natural glycoprotein agglutinin has been isolated, whose carbohydrate component contains muramic rather than sialic acid. Moreover, an induced bacterial agglutinin has been purified, although this induction is relatively rare in gastropods. Lysozyme-like molecules have also been detected and they act like alarm molecules in inflammatory reactions. Taken together, the humoral and cellular investigations, the bacterial clearance studies and the specific responses observed in transplantation experiments are all in favour of the presence of a memorytype response of short duration. Finally, interrelations appear to exist between the immune and neuroendocrine systems. ACTH and ß-endorphin-immunoreactive molecules have been detected in serum and SH, and these molecules appear to play a physiological role in the process of phagocytosis and in stress response.
