Alcoholic liver disease (ALD) is caused by long-term consumption of alcohol and has become an important social and medical problem. Intestinal fungal flora (mycobiota) play an important role in ALD, so we used the mycobiota as an entry point to explore the mechanism of action of Paeonol against ALD. Here, we found that Paeonol is effective against ALD inflammatory lesions and relieves liver fat lesions. Furthermore, we found that after the treatment of Paeonol, the fungal dysbiosis is improved, and the fungal abundance is reduced, and the translocation of β-glucan to the liver and its mediated Dectin-1/IL-1β signaling pathway is blocked. Our study shows that paeonol ameliorated acute ALD-related inflammatory injury to the liver by alleviating intestinal fungal dysbiosis and inhibiting the mycobiota-mediated Dectin-1/IL-1β signaling pathway.

pneumonia (PJP) remains a significant cause of morbidity and mortality during AIDS. In AIDS, the absence of CD4 immunity results in exuberant and often fatal PJP. In addition, organism clearance requires a balanced macrophage response since excessive inflammation promotes lung injury and respiratory failure.

Self-adjuvanted vaccine delivery platforms possess potential for targeted delivery of antigens and initiation of potent immune responses. Although aluminum-containing adjuvants have been approved and widely used in human vaccines, their effectiveness in inducing Th1-type immune responses is far from satisfactory. To facilitate antigen delivery and activate potent antitumor immune responses, a self-adjuvanted nanovaccine (CPBG-Al@OVA) is constructed by functionalizing aluminum hydroxide with β-1,3-glucan, which recognizes pattern recognition receptors via Dectin-1.

The fungal community of the skin microbiome is dominated by a single genus, Malassezia. Besides its symbiotic lifestyle at the host interface, this commensal yeast has also been associated with diverse inflammatory skin diseases in humans and pet animals. Stable colonization is maintained by antifungal type 17 immunity.

Immune stimuli are able to trigger long-term protective effects through mechanisms of trained immunity, which has attracted increasing attention. Although the existence of trained immunity has evidenced in teleost fish, while there were no such reports in pufferfish (Takifugu obscurus) so far. Therefore, the present study aimed to evaluate the induction of β-glucan and mannan on the trained immunity and their protective efficacy against Vibrio harveyi re-stimulation in pufferfish.

Dectin-1, a C-type lectin, plays important roles in the induction of antifungal immunity. Caspase recruitment domain-containing protein 9 (CARD9) is essential for the dectin-1-induced production of cytokines through the activation of NF-κB. However, the molecular mechanisms underlying the dectin-1-mediated activation of CARD9 have not been fully elucidated.
