Ethnopharmacological Relevance: Alzheimer's disease (AD) is the most prevalent form of dementia, characterized by a complex pathogenesis that includes Aβ deposition, abnormal phosphorylation of tau protein, chronic neuroinflammation, and mitochondrial dysfunction. In traditional medicine, ginseng is revered as the 'king of herbs'. Ginseng has the effects of greatly tonifying vital energy, strengthening the spleen and benefiting the lungs, generating fluids and nourishing the blood, and calming the mind while enhancing intelligence.

Knowledge on the structure and composition of the haematopoietic tissue (HT) is essential to understand the basic immune functions of the immune system in any species. For reptiles, it is extremely limited, hence we undertook an in-depth in situ investigation of the HT (bone marrow, thymus, spleen, lymphatic tissue of the alimentary tract) in the common boa (Boa constrictor). We also assessed age- and disease-related changes, with a special focus on Boid Inclusion Body Disease, a highly relevant reptarenavirus-associated disease in boid snakes.

von Willebrand factor (vWF) is a large multimeric sialoglycoprotein that plays key roles in normal haemostasis, inflammation regulation, angiogenesis and cancer metastasis in mammals. The gene, protein sequences and functions of vWF in flounder Paralichthys olivaceus (PovWF) were analysed in this study. PovWF possesses an 8550-bp open reading frame (ORF) that encodes a 2849 amino acid protein.

Article Synopsis
  • Diabetes mellitus (DM) is linked to cognitive impairment, with the study focusing on spleen tyrosine kinase (SYK) as a potential mechanism behind this connection.
  • In experiments on diabetic mice, cognitive deficits were observed, and SYK activation was associated with increased neuronal cell death (pyroptosis) in the hippocampus.
  • The research showed that inhibiting SYK significantly improved cognitive function and reduced signs of neuronal damage, suggesting that targeting SYK could be a therapeutic approach for cognitive issues in DM patients.
