MetabolomicsBacterial Pathogens Hijack the Innate Immune Response by Activation of the Reverse Transsulfuration Pathway

The reverse transsulfuration pathway is the major route for the metabolism of sulfur-containing amino acids. The role of this metabolic pathway in macrophage response and function is unknown. We show that the enzyme cystathionine γ-lyase (CTH) is induced in macrophages infected with pathogenic ba...

MetabolomicsInnate Immune Training of Human Macrophages by Cathelicidin Analogs
Trained innate immunity can be induced in human macrophages by microbial ligands, but it is unknown if exposure to endogenous alarmins such as cathelicidins can have similar effects. Previously, we demonstrated sustained protection against infection by the chicken cathelicidin-2 analog DCATH-2. Thus...

MetabolomicsPlatycodin D attenuates alcohol-associated fatty liver disease by suppressing TLR4–NF-κB and activating PPAR signaling

Alcohol-associated fatty liver disease (AFLD) is driven by ethanol-induced metabolic dysregulation and hepatic inflammation, with gut dysbiosis and endotoxin-triggered innate immune activation implicated in disease progression. Platycodin D (PD), a triterpenoid saponin from Platycodon grandifloru...

TranscriptomicsGene expression profiles of LPS-stimulated RAW264.7 macrophages overexpressing Tbc1d23 novel innate immune gene
We previously identified Tbc1d23 as a candidate novel regulator of innate immunity using comparative genomics RNAi screens in C. elegans and mouse macrophages. Using mice with an engineered knockout mutation in Tbc1d23 and macrophages engineered to overexpress Tbc1d23, we now show that Tbc1d23 is a ...

GenomicsBcl6 and NFkB cistromes mediate opposing reulation of the innate immune response
Here, using ChIP-seq, we define the NF-κB cistrome which is comprised of 31,070 cis-acting binding sites responsive to LPS-induced signaling. In addition, we demonstrate that the transcriptional repressor B-cell lymphoma 6 (Bcl-6) regulates nearly a third of the Tlr4-regulated transcriptome and tha...

TranscriptomicsVirus-misplaced host protein activates innate immunity
Discrimination between self vs. non-self and adequate response to infection and tissue damage are fundamental functions of the immune system. The rapid and global spread of known and emerging viruses is a testament that the timely detection of viral pathogens that reproduce within host cells, presen...

MetabolomicsLily polysaccharides alleviate colitis through the microbiota/N8AS/cGAS-STING signaling axis

With the rising incidence of IBD and limitations of current therapies, novel strategies are urgently needed. Recent studies have highlighted natural products in colitis treatment. Here, we investigated the therapeutic effects and mechanisms of lily polysaccharides (LP) in DSS-induced ulcerative c...

MetabolomicsSuccinate drives macrophage inflammation by promoting GPR91 mitochondrial signaling in rheumatoid arthritis

Succinate is implicated in rheumatoid arthritis (RA) and other inflammatory diseases via its receptor, G protein-coupled receptor 91 (GPR91). Despite its therapeutic potential, conflicting reports on its inflammatory roles have hindered GPR91-targeted treatm...

TranscriptomicsModulation of the immune system during postpartum uterine inflammation [expression]
Post-partum uterine inflammation (endometritis) is associated with lower fertility at both the time of infection and after the inflammation has resolved. It was hypothesized that aberrant DNA methylation may be involved in the sub-fertility associated with post-partum uterine inflammation. The objec...
