TL;DR: The current insight attempts to provide an updated and balanced discussion on the role of galectin‐3 as a complex endogenous immune modulator with translational value in different neurological disorders including stroke and neurodegenerative diseases, such as Alzheimer's disease, Huntington's disease and Parkinson's disease.
Abstract: Galectins are soluble β-galactoside-binding proteins found in all multicellular organisms. Galectins may act as danger-associated molecular patterns in innate immunity and/or as pattern-recognition receptors that bind to pathogen-associated molecular patterns. Among different galectin family members, galectin-3 has been the focus of studies in neurodegenerative diseases in recent years. This lectin modulates brain innate immune responses, microglia activation patterns in physiological and pathophysiological settings in a context-dependent manner. Galectin-3 is considered as a pivotal tuner of macrophage and microglial activity. Indeed galectin-3 acts as a double edged sword in neuroinflammatory context and this multimodal lectin has diverse roles in physiological and pathophysiological conditions. Better understanding of galectin-3 physiology (its extracellular and intracellular actions) and structure (its C terminus vs. N terminus) is instrumental to design molecules that selectively modulate galectin-3 function toward neuroprotective phenotypes. Several experimental studies using different approaches and methods have demonstrated both protective and deleterious effects of galectin-3 in neuroinflammatory diseases. According to the crucial role of galectin-3 in modulation of innate immune response in brain, it is an attractive target in drug discovery of neurodegenerative diseases. The current insight attempts to provide an updated and balanced discussion on the role of galectin-3 as a complex endogenous immune modulator. This helps to have a better insight into the development of galectin-3 modulators with translational value in different neurological disorders including stroke and neurodegenerative diseases, such as Alzheimer's disease, Huntington's disease and Parkinson's disease.

TL;DR: The results suggest that BmGalectin-4 may function as a pattern recognition receptor primarily in silkworm fertilized eggs.
Abstract: Galectins (S-type lectins) are an ancient family of lectins with the β-galactoside binding activity. In mammals, galectins play essential roles in many biological processes, such as development, immune homeostasis and tumor progression. However, few studies have been devoted to their functions in insects. Here, we characterized the only dual-CRD galectin in the silkworm Bombyx mori (BmGalectin-4). BmGalectin-4 cDNA possesses an open reading frame of 1089 bp, which encodes a putative galectin of 363 amino acids containing tandem carbohydrate recognition domains (CRDs). BmGalectin-4 was expressed in various tissues but the protein was most abundant in fertilized eggs. Its transcript level in fertilized eggs was upregulated upon bacterial challenge. Recombinant BmGalectin-4 purified from Escherichia coli bound to bacterial cell wall components and bacterial cells. In addition, the recombinant protein induced bacterial agglutination, but did not have antibacterial activity against selected microorganisms. Taken together, our results suggest that BmGalectin-4 may function as a pattern recognition receptor primarily in silkworm fertilized eggs.

TL;DR: This study shows for the first time that both galectin-14 and galECTin-11 are produced in liver tissue after chronic liver fluke infection and that they can directly interact with the parasite in the bile ducts.
