Abstract
Inhibiting pathological secretion of Interleukin-1β has shown beneficial effects in disease models and in the clinic and thus there is interest in finding inhibitors that can reduce its release from macrophages in response to their activation by foreign pathogens. We used an in vitro human macrophage model to investigate whether ICRF-193, a Topoisomerase II inhibitor could modulate IL1B mRNA expression and IL-1β secretion. These macrophage-like cells readily secrete IL-1β in response to Lipopolysaccharide (LPS). Upon exposure to a non-toxic dose of ICRF-193, IL-1β secretion was diminished by ~ 40%; however, level of transcription of IL1B was unaffected. We show that there was no Topoisomerase 2B (TOP2B) binding to several IL1B gene sites, which may explain why ICRF-193 does not alter IL1B mRNA levels. Hence, we show for the first time that ICRF-193 can reduce IL-1β secretion. Its low cost and the development of water-soluble prodrugs of ICRF-193 warrants its further investigation in the modulation of pathological secretion of this cytokine for the treatment of inflammatory disorders.

DNA damage independent inhibition of NF-κB transcription by anthracyclines. eLife 2022; 11:77443.

Abstract
Anthracyclines are among the most used and effective anticancer drugs. Their activity has been attributed to DNA double-strand breaks resulting from topoisomerase II poisoning and to eviction of histones from select sites in the genome. Here, we show that the extensively used anthracyclines Doxorubicin, Daunorubicin, and Epirubicin decrease the transcription of nuclear factor kappa B (NF-κB)-dependent gene targets, but not interferon-responsive genes in primary mouse (Mus musculus) macrophages. Using an NMR-based structural approach, we demonstrate that anthracyclines disturb the complexes formed between the NF-κB subunit RelA and its DNA-binding sites. The anthracycline variants Aclarubicin, Doxorubicinone, and the newly developed Dimethyl-doxorubicin, which share anticancer properties with the other anthracyclines but do not induce DNA damage, also suppressed inflammation, thus uncoupling DNA damage from the effects on inflammation. These findings have implications for anticancer therapy and for the development of novel anti-inflammatory drugs with limited side effects for life-threatening conditions such as sepsis.

Am J Reprod Immunol 2021; 86:e13493.

Abstract
The disruption of the inflammatory microenvironment in the uterus affects pregnancy outcome. However, the exact quantification and distribution of leukocyte subpopulations in the uterus in preeclampsia (PE) have not been clearly characterized. Inflammasomes promote the release of proinflammatory cytokines interleukin (IL)-β and IL-18. A higher expression of NLRP3 inflammasome in placentas contributes to excessive inflammation in PE. However, related studies on the uterus are scarce. We aimed to investigate changes in the infiltration of leukocyte subpopulations in decidual and uterine tissues, and explore the role of activation of uterine NLRP3 inflammasomes in PE. Decidual tissues were collected from normotensive pregnant women and preeclamptic women. A PE-like model was established via administration of lipopolysaccharide to normal pregnant rats. Uterine and decidual tissues were collected from all experimental groups. It was found that the number of leukocytes was significantly elevated in decidual and uterine tissues in PE patients compared to normal controls. The leukocytes (predominantly macrophages and NK cells) particularly infiltrated into the decidua and uterine decidua in PE-like rats, and these were sparse in the myometrium. The NLRP3 immunoreactivity in the uterus was extremely little in control rats, its immunoreactivity and caspase-1 immunoreactivity were significantly elevated in the PE-like rats; the mRNA expression results also indicated an upward trend in the activation of NLRP3 inflammasomes. These results support that leucocyte infiltration in the decidua and uterine deciduas, and the activation of NLRP3 inflammasome in the uterus, which participate in the pathogenesis, are responsible for the excessive inflammation at the maternal-fetal interface during PE.

Abstract
The innate immune system represents the host’s first-line defense against pathogens, dead cells or environmental factors. One of the most important inflammatory pathways is represented by the activation of the NOD-like receptor (NLR) protein family. Some NLRs induce the assembly of large caspase-1-activating complexes called inflammasomes. Different types of inflammasomes have been identified that can respond to distinct bacterial, viral or fungal infections; sterile cell damage or other stressors, such as metabolic imbalances. Epigenetic regulation has been recently suggested to provide a complementary mechanism to control inflammasome activity. This regulation can be exerted through at least three main mechanisms, including CpG DNA methylation, histones post-translational modifications and noncoding RNA expression. The repression or promotion of expression of different inflammasomes (NLRP1, NLRP2, NLRP3, NLRP4, NLRP6, NLRP7, NLRP12 and AIM2) through epigenetic mechanisms determines the development of pathologies with variable severity. For example, our team recently explored the role of microRNAs (miRNAs) targeting and modulating the components of the inflammasome as potential biomarkers in bladder cancer and during therapy. This suggests that the epigenetic control of inflammasome-related genes could represent a potential target for further investigations of molecular mechanisms regulating inflammatory pathways.
