Abstract Invertebrates lack an adaptive immune system, but have developed efficient innate immune systems to defend themselves against foreign materials. Molecular structures and functions of various defense components that participate in immune processes are being discovered. New molecules such as fibrinogen-related proteins (FREPs) are being uncovered that might have the potential to recognize and attack specific pathogens, while the roles of better-studied molecules continue to expand.

The immune role of C-type lectins in molluscs
This chapter provides a short review of C-type lectins in molluscs, including their structure, function and possible use in science and technology.
Sialic acid binding lectins (SABL) from molluscs, a review and insilico study of SABL from Solen grandis and Limax flavus
Structural peculiarities in SABL from Solen grandis and Limax flavus has domains bearing homology to fibrinogen-related domains (Fred) superfamily with probable role in blood clotting and are unique amongst molluscan S ABLs.
First report on a N-acetylneuraminic acid specific lectin from the marine alpheid shrimp Alpheus digitalis Complex De Haan 1844 (Crustacea: Decapoda: Alpheidae)
Hemagglutination inhibition assay performed with different carbohydrates and glycoproteins revealed unique specificity of hemolymph agglutinin for N-acetylneuraminic acid and fetuin.
Sialic acid specific lectins from Episesarma tetragonum (Decapoda, Grapsidae): isolation, purification and characterization
The physicochemical characteristics of the minor agglutinin showed that its hemagglutinating activity was calcium dependent, optimum at pH 8 – 9.5 and temperature 0 – 37 °C, and strong inhibition of purified minor lectin by bovine submaxillary mucin and non-inhibitory action of de-O-acetylated bovines submaxilla mucin suggested that the lectin was O-acetym sialic acid specific.
A Novel Bifunctional Hybrid with Marine Bacterium Alkaline Phosphatase and Far Eastern Holothurian Mannan-Binding Lectin Activities
The bifunctional hybrid holothurian's lectin could be promising tool for developing non-invasive methods for biological markers assessment, particularly for improving the MBL-AJ-based method for early detection of a malignant condition in cervical specimens.
What is an international journal?
This editorial urges the authors of the Italian Journal of Zoology to promote an idea of zoology that is typically Italian, and is proud to realize that this is the first issue of the journal in which the majority of the papers have non-Italian authors.

The present status of the molecular structures and functions of various defense components that participated in innate immune systems have been established in Arthropoda, such as, insects, the horseshoe crab, freshwater crayfish, and the protochordata ascidian are described.
Humoral Recognition Factors in the Arthropoda. The Specificity of Chelicerata Serum Lectins
Serum lectins from chelicerates and other arthropods represent heterogeneous populations which can bind a wide variety of carbohydrates, many of them present on bacteria as D-galactose, 2-keto-3-deoxyoctonate, glucuronic acid, N-acetylmuramic acid, and colominic acid.
Role of tachylectins in host defense of the Japanese horseshoe crab Tachypleus tridentatus.
Innate immunity is phylogenetically older than acquired immunity and is present in all multicellular organisms, and proteins pre-exist in hosts, or are rapidly induced within hours of infection.
Lectins: Models of Natural and Induced Molecules in Invertebrates
It is not possible to understand the function of defence molecules, whether they are acting in recognition, modulation or signalling, without regard to their interplay with other components of the immune system.
Innate immunity in insects: the role of multiple, endogenous serum lectins in the recognition of foreign invaders in the cockroach, Blaberus discoidalis.
The results show that the endogenous lectins in the cockroach hemolymph are capable of acting as nonself recognition molecules for a wide range of microorganisms, and thus obviate the necessity of Abs in these animals.
Collectins and pulmonary innate immunity
Summary: The surfactant‐associated proteins SP‐A and SP‐D are members of a family of host defense lectins, designated collectins. There is increasing evidence that these pulmonary, epithelial‐derived
A novel lectin with a fibrinogen‐like domain and its potential involvement in the innate immune response of Armigeres subalbatus against bacteria
Results suggest that AL‐1 might function as a pattern recognition receptor in the immune response in Ar.
Self/Non-Self Recognition in Invertebrates
The evidence indicates that some invertebrates may possess a capacity for specific recognition of self, and hence it is argued that the simplest mechanism of ensuring self-tolerance is one where self is specifically recognized.
