The main polysaccharide component of the thickened cell walls in the storage parenchyma of Lupinus angustifolius L. cotyledons is a linear (1-->4)-beta-linked D-galactan, which is mobilised after germination (L. A. Crawshaw and J.S.G Reid, 1984, Planta 160, 449-454). The isolation

The species Actinomyces serovar WVA963 is among the 20 bacteria most frequently isolated from human subgingival plaque. The interactions of this species with streptococci are inhibited by lactose, a function associated with type 2 fimbrial surface structures in Actinomyces naeslundii.

Lectin AAL (Agrocybe aegerita lectin) from the edible mushroom A. aegerita is an antitumor protein that exerts its tumor-suppressing function via apoptosis-inducing activity in cancer cells. The crystal structures of ligand-free AAL and its complex with lactose have been determined.

The effects of the second glutamic acid (E) in the C-terminal CRDs on the hemagglutination and lactose-binding characteristics of the recombinant galectins of nematode Haemonchus contortus were observed using two isoforms of recombinant galectins as models, and the sugar-binding abilities

Interactions between B cell progenitors and bone marrow stromal cells are essential for normal B cell differentiation. We have previously shown that an immune developmental synapse is formed between human pre-B and stromal cells in vitro, leading to the initiation
