Article Title: Inhibition of IRAK4 by microbial trimethylamine blunts metabolic inflammation and ameliorates glycemic control

doi: 10.1038/s42255-025-01413-8

Figure Lengend Snippet: ( a ) Confirmation of a physical interaction between TMA and IRAK4 using TMA at concentrations ranging from 0.1 nM to 100 µM, resulting in a dissociation constant ( K d ) of 14 nM. ( b – e ) Physical interaction test between TMA and the four hits identified using a kinome screen, using TMA concentrations ranging from 0.1 nM to 100 µM for ( b ) ANKK1, ( c ) HIPK2, ( d ) JAK2 and ( e ) NDR1. For (b-e) N = 2 biological repeats. IRAK4 kinase activity is not significantly inhibited by choline ( f ), TMAO ( g ) or DMB ( h ), while TMA does not have any inhibitory effect on IRAK-1 kinase activity (average of N = 2 biological repeats) ( i ). ( j , k ) Phosphorylation for pThr183/Tyr185 SAPK/JNK/SAPK/JNK ( j ) and pThr180/Tyr182 p38MAPK/p38MAPK ( k ) densitometric ratios, represented by each dot. Data are means ± s.e.m. One-way ANOVA followed by Tukey’s post hoc tests (superscript letters for factor levels P < 0.05) on log-transformed data. Source data are provided.
