Kaempferol exerts anti-inflammatory effects by accelerating Treg development via AhR-mediated and PU.1/IRF4-dependent transactivation of the Aldh1a2/RALDH2 gene in dendritic cells

This study identifies kaempferol as a flavonoid that enhances Treg development via AhR-mediated and PU.1/IRF4-dependent activation of Aldh1a2/RALDH2 in dendritic cells, reducing inflammation in a food allergy model.

NR4A3 deficiency ameliorates contact hypersensitivity and exacerbates psoriasis by regulating gene expression in dendritic cells

This study shows NR4A3 deficiency reduces contact hypersensitivity but worsens psoriasis by altering dendritic cell gene expression.

The gut lactic acid bacteria metabolite, 10-oxo-cis-6,trans-11-octadecadienoic acid, suppresses inflammatory bowel disease in mice by modulating the NRF2 pathway and GPCR-signaling

This study identifies 10-oxo-cis-6,trans-11-octadecadienoic acid as an anti-inflammatory metabolite that suppresses colitis in mice via NRF2 pathway activation and GPCR signaling.

Immunostimulatory effects of Bacillus coagulans SANK70258

This study evaluates the immunomodulating effects of Bacillus coagulans SANK70258, showing it induces high IFN-γ and IgA production compared to other lactic acid bacteria.

Kaempferol suppresses the activation of mast cells by modulating the expression of FcϵRI and SHIP1

This study shows kaempferol suppresses mast cell activation by reducing FcεRI surface expression and increasing SHIP1 levels, independent of transcription and translation.

Butyrate, valerate, and niacin ameliorate anaphylaxis by suppressing IgE-dependent mast cell activation: Roles of GPR109A, PGE2, and epigenetic regulation

This study shows that butyrate and valerate reduce IgE-mediated mast cell activation by enhancing PGE2 release and GPR109A signaling, while niacin also alleviates anaphylaxis through similar mechanisms.

A rose flavor compound activating the NRF2 pathway in dendritic cells ameliorates contact hypersensitivity in mice

This study shows that β-damascone, a rose compound, activates the NRF2 pathway in dendritic cells to reduce immune responses and alleviate contact hypersensitivity in mice.
