Article Abstract
Galectins, a family of glycan-binding proteins have been shown to bind a wide range of glycans. In the cytoplasm, these glycans can be endogenous (or "self"), originating from damaged endocytic vesicles, or exogenous (or "non-self"), found on the surface of invading microbial pathogens. Galectins can detect these unusual cytosolic exposures to glycans and serve as critical regulators in orchestrating immune responses in innate and adaptive immunity. This review provides an overview of how galectins modulate host cellular responses, such as autophagy, xenophagy, and inflammasome-dependent cell death program, to infection.

Background: Mesenchymal stem cells (MSCs) are one of the effective treatments for acute graft-versus-host disease (aGVHD) following allogeneic hematopoietic stem cell transplantation (allo-HSCT) due to their potent immunoregulatory function. Given the limited quantity and high heterogeneity of freshly isolated MSCs, extensive expansion is essential for clinical application. Prolonged passaging of MSCs leads to a decline in therapeutic efficacy, with the underlying mechanisms remaining unclear.

Galectins are a family of carbohydrate-binding proteins known to maintain intestinal microbiota homeostasis. Emerging evidence suggests that the bacterial symbiont plays a role in modulating insecticide resistance in insect. However, whether galectins influence insecticide susceptibility through microbiota regulation remains unclear.

Galectins are glycan-binding proteins (GBPs) characterized by conserved carbohydrate recognition domains (CRDs). Galectin-9, which contains two CRDs, regulates immune responses through interactions with glycoproteins. However, the full-length structure of galectin-9 remains unresolved.

Unlabelled: Galectin-1 is a protein from the lectin family that is capable of recognizing β-galactosides, and it is involved in modulating the inflammatory response and tissue homeostasis. However, the presence and distribution of galectin-1 in pulp tissue, as well as its role in pulp inflammation, are poorly understood. Although galectin-1 has been reported to be present in healthy and necrotic pulp tissue at the proteomic level, the modifications and implications of these changes in galectin in tissues with irreversible pulpitis and infiltrating macrophages that could help clarify the inflammatory phenomenon have not yet been described.

Background: Chronic insomnia (CI) commonly co-occurs with chronic migraine (CM), and neuroinflammation may underlie this association. Galectin-3, a pro-inflammatory mediator, has been implicated in migraine and sleep regulation, but its role in CM-related insomnia and its link to NLRP3 inflammasome activation remain unclear.
Methods: We conducted a case-control study of 150 CM patients, categorized by CI status using ICSD-3 criteria and Pittsburgh Sleep Quality Index (PSQI).
