Functional consequences for most inflammatory disease-associated loci are incompletely defined, including in the LACC1 (C13orf31) region. Here we show that human peripheral and intestinal myeloid-derived cells express laccase domain-containing 1 (LACC1); LACC1 is expressed in both the cytoplasm and mitochondria. Upon NOD2 stimulation of human macrophages, LACC1 associates with the NOD2-signalling complex, and is critical for optimal NOD2-induced signalling, mitochondrial ROS (mtROS) production, cytokine secretion and bacterial clearance. LACC1 constitutively associates with succinate dehydrogenase (SDH) subunit A, and amplifies pattern recognition receptor (PRR)-induced SDH activity, an important contributor to mtROS production. Relative to LACC1 Ile254, cells transfected with Crohn's disease-risk LACC1 Val254 or LACC1 with mutations of the nearby histidines (249,250) have reduced PRR-induced outcomes. Relative to LACC1 Ile254 carriers, Val254 disease-risk carrier macrophages demonstrate decreased PRR-induced mtROS, signalling, cytokine secretion and bacterial clearance. Therefore, LACC1 is critical for amplifying PRR-induced outcomes, an effect that is attenuated by the LACC1 disease-risk variant.

This study provided analysis of differentially expressed genes (DEGs) in Pleurotus ostreatus under the interaction with Dichomitus squalens and Trametes versicolor, which is valuable for exploration on the fungal defence system against stressful condition caused by interspecific antagonistic interaction. Our result showed significant upregulation of abundant defence-related genes encoding laccase, manganese peroxidase, aldo-keto reductase, and glutathione S-transferase, which all play important roles in oxidative stress-resistant response. Importantly, Lacc2 and Lacc10 were found to be dominantly induced laccase genes in P. ostreatus under interspecific interaction. Meanwhile, a large number of carbohydrate metabolism-related and energy production-related genes involved in nutrient and territory competition were also enhanced. These genes were annotated as glycoside hydrolase, citrate synthase, malate dehydrogenase, succinate dehydrogenase, succinyl-CoA synthetase, NADH dehydrogenase, cytochrome c reductase/oxidase, and ATP synthase. Also, 12 DEGs were selected for validation by quantitative real-time PCR (qRT-PCR), all these genes showed consistent expression between the result of qRT-PCR and RNA-seq.
