Targeting APT2 improves MAVS palmitoylation and antiviral innate immunity

Project description:Innate immunity serves as the primary defense against viral and microbial infections in humans. Among its components, retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) are well-characterized intracellular pattern-recognition proteins that trigger innate immune responses upon viral infection. However, the precise influence of cellular metabolites, especially fatty acids, on the regulation of RLR-mediated antiviral innate immunity remains largely elusive. Here, through screening a metabolite library, palmitic acid (PA) has been identified as a crucial metabolite responsible for modulating antiviral infections. Mechanistically, PA induces the palmitoylation of MAVS, leading to MAVS aggregation and subsequent activation, thereby enhancing the innate immune response against viral infections. Functionally, the enzyme palmitoyl-transferase ZDHHC24 plays a key role in catalyzing the palmitoylation of MAVS at both C46 and C79 residues, thereby facilitating the transduction of RLR-mediated TBK1-IRF3-IFN signaling pathway, particularly under conditions of PA stimulation or high-fat diet feeding. Conversely, the absence of ZDHHC24 significantly attenuates virus-induced innate immune responses in both cells and mice. Moreover, APT2 counteracts with ZDHHC24 to de-palmitoylate MAVS, thus inhibiting the antiviral response. Consequently, inhibition of APT2 using compounds like ML349 effectively reverses MAVS palmitoylation and activation in response to antiviral infections. These findings underscore the critical role of PA and ZDHHC24 in regulating antiviral innate immunity through MAVS palmitoylation, and suggest potential therapeutic strategies for combating viral infections, such as enhancing PA intake or specifically targeting APT2.

Nuclear SIRT3 counteracts human stem cell senescence

Project description:Sirtuin 3 (SIRT3) is an NAD+-dependent deacetylase involved in various physiological and pathological processes. However, the role of SIRT3 in regulating human stem cell senescence remains largely unknown. Here, we observed the downregulated expression of SIRT3 in senescent human mesenchymal stem cells (hMSCs). SIRT3 deficiency accelerated cellular senescence in hMSCs, along with compromised nuclear integrity, loss of heterochromatin and increased DNA damage. These aging-associated nuclear defects were attenuated by the reintroduction of SIRT3. Mechanistic studies demonstrated the interaction of SIRT3 with nuclear envelope proteins and heterochromatin-associated proteins. Further findings revealed that SIRT3 deficiency led to the loss of lamina-associated domains (LADs) from the nuclear lamina, increased chromatin accessibility and aberrant transcription of repetitive sequences. Meanwhile, the overexpression of nuclear-localized SIRT3 rescued the senescence phenotypes. Taken together, our study reveals a novel role of nuclear SIRT3 in stabilizing heterochromatin and counteracting hMSC senescence, which may provide new clinical therapeutic targets to ameliorate aging-related diseases.

Quantitative proteomic analysis of tumor tissues before and during Bacillus Calmette-Guérin instillation in bladder cancer

Project description:The alteration of protein expression profile mediated by Bacillus Calmette-Guérin (BCG) treatment remains unclear and is rarely studied. Three paired before BCG(pre-BCG) and during BCG(on-BCG) tissues were collected for proteomicsanalyses to describe the proteomic changes caused by BCG.

Nasopharyngeal carcinoma cell lines (copy number analysis)

Project description:Five NPC cell lines (HONE1, CNE1, CNE2, 5-8F, and 6-10B) and an immortalized nasopharyngeal epithelial cell line NP69 were evaluated with 250K SNP arrays (Affymetrix) to detect the genome-wide DNA copy number alterations. The same type of data of 45 Chinese samples from the HapMap project was used as normal control. Data was analyzed using GCOS (GeneChip operating software, Ver.1.4), GTYPE (GeneChip Genotyping Analysis Software, Ver.4.1), and CNAT (chromosome copy number analysis tool, Ver.4.0, BRLMM algorithm).

Metabolic regulation of host defense against influenza virus infection through sensing oxaloacetate

Project description:Metabolic pathways instructing the cellular fate and function, however, the exact roles of metabolites in host immune responses remain undefined. Using unbiased metabolomics and pharmacological inhibition analysis, we report natural metabolic intermediate, oxaloacetate (OAA) primes effective broad-spectrum innate immunity against viral infection. OAA serves as an immune signal, rather than alters the metabolic flux to prompt antiviral immunity. Malate dehydrogenase 1 (MDH1) senses OAA to undergo dimerization, thus functions as a scaffold to recruit transcription factor ETS2 for phosphorylation by kinase TAOK1 at serine 313. Phosphorylated ETS2 is involved in the transcriptional regulation of TANK-binding kinase 1 (TBK1). OAA deficiency caused by genetic ablation and enzymatic inhibition of the ATP-citrate lyase (ACLY) decreases the antiviral immune responses through MDH1-TAOK1-ETS2-TBK1 pathway in vivo, and makes mice more susceptible to lethal viral infection. Taken together, our findings delineate an OAA-initiated immunometabolic circuit that links metabolic pathway and antiviral immune responses.
