Aureobasidium pullulans is a polymorphic black yeast-like fungus found in soil, water, and plant surfaces worldwide. Unlike beta glucan derived from oats, barley, or baker yeast, the beta glucan produced by Aureobasidium pullulans has a unique high-molecular-weight beta-1,3-1,6-glucan structure — a branching architecture that enables strong binding to immune receptors including Dectin-1 (CLEC7A) on macrophages, dendritic cells, and natural killer (NK) cells. This receptor interaction triggers downstream NF-kB and MAPK signaling, leading to upregulation of cytokines including TNF-alpha, IL-6, and IFN-gamma.
Since the 1990s, researchers in Japan, South Korea, and Europe have published extensively on this compound. Studies are indexed in PubMed (NIH National Library of Medicine), the WHO Food Safety database, and leading immunology journals. Our database indexes 124 peer-reviewed studies with DOI-verified citations covering immune activation, anti-tumor activity, antiviral mechanisms, gut microbiome modulation, and metabolic health.
The primary activation pathway involves binding to Dectin-1 (CLEC7A), expressed on myeloid cells including macrophages, dendritic cells, and neutrophils. Dectin-1 recognition triggers receptor dimerization, ITAM phosphorylation, and Syk kinase activation — leading to CARD9-mediated NF-kB activation, inflammasome priming, and T helper cell polarization toward Th1 and Th17 responses.
A documented Dectin-1-independent pathway via complement receptor 3 (CR3, CD11b/CD18) provides secondary activation, particularly significant for patients with impaired Dectin-1 expression — observed in certain immunodeficiency states and following prolonged corticosteroid use. CR3-mediated activation leads to respiratory burst, enhanced phagocytosis, and ADCC against opsonized tumor cells.
The majority of published research on Aureobasidium pullulans beta glucan is concentrated in Japanese and Korean scientific literature, much of which is not indexed in mainstream English databases. This resource consolidates that literature with DOI-verified citations and structured summaries accessible to both researchers and informed general readers.
Each entry includes: original DOI, author affiliations, study design (in vitro / animal model / human clinical trial), sample size, primary outcomes, and a plain-language AI-assisted summary — organized by therapeutic area, molecular pathway, and study type for evidence-based exploration.
