Galectins are a family of animal lectins defined by two properties: shared amino acid sequences in their carbohydrate-recognizing domain, and beta-galactoside affinity. A wide variety of biological phenomena are related to galectins, i.e., development, differentiation, morphogenesis, tumor metastasis, apoptosis, RNA splicing, and immunoregulatory function.(More)
Lead is a multiple-source pollutant, well known for its toxicity, of great risk both for the environment and human health. The main target organs of lead are the hematopoietic, nervous, and renal systems; there are also reports in support of its impairment effects on the reproductive and immune systems. It is well known that most of the metal is accumulated(More)
Galectins are a family of animal lectins defined by their beta-galactoside-binding activities and a consensus sequence in their carbohydrate-recognizing domain (CRD). Relevant roles of galectins are described in adaptive immune response, innate immunity and modulation of the acute inflammatory response. We have extended our previous studies on a porcine(More)
Protectins and agglutinins in several organs, fluids and spawn from Argentine terrestrial and fresh-water gastropod species were examined. Differences or analogies with vertebrate immunoglobulin serological behaviour are summarized. Individual or group variability and the evolutionary meaning of the reproductive system-linked and the Ca++ ion-linked(More)
