Abstract
Listeria monocytogenes (Lm) poses a significant threat to human health. TRIM32, an E3 ubiquitin ligase, plays a critical role in regulating immune responses to pathogen infections. Previous studies have shown that TRIM32 deficiency significantly impairs IFN-β production. In this study, we demonstrate that TRIM32 enhances IFN-β release upon activation by cyclic di-GMP (c-di-GMP). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses revealed that TRIM32 deficiency upregulates genes associated with metabolic pathways while downregulating those involved in cytokine signaling and inflammatory responses. Western blot analysis further indicated a significant reduction in ERK and JNK phosphorylation in splenocytes and peritoneal macrophages, suggesting that TRIM32 modulates the MAPK signaling pathway. Additionally, the duration of p38, STAT, and TBK1 phosphorylation was shortened in bone marrow-derived macrophages. Collectively, these findings highlight the role of TRIM32 in enhancing the host immune response against Lm infection.
期刊介绍:
Microbes and Infection publishes 10 peer-reviewed issues per year in all fields of infection and immunity, covering the different levels of host-microbe interactions, and in particular:
the molecular biology and cell biology of the crosstalk between hosts (human and model organisms) and microbes (viruses, bacteria, parasites and fungi), including molecular virulence and evasion mechanisms.
the immune response to infection, including pathogenesis and host susceptibility.
emerging human infectious diseases.
systems immunology.
molecular epidemiology/genetics of host pathogen interactions.
microbiota and host "interactions".
vaccine development, including novel strategies and adjuvants.
Clinical studies, accounts of clinical trials and biomarker studies in infectious diseases are within the scope of the journal.
Microbes and Infection publishes articles on human pathogens or pathogens of model systems. However, articles on other microbes can be published if they contribute to our understanding of basic mechanisms of host-pathogen interactions. Purely descriptive and preliminary studies are discouraged.
