Epigenetic and immunological indicators of IPEX disease in subjects with FOXP3 gene mutation. J Allergy Clin Immunol 2023; 151:233-246.e10.

Abstract
BACKGROUND Forkhead box protein 3 (FOXP3) is the master transcription factor in CD4+CD25hiCD127lo regulatory T (Treg) cells. Mutations in FOXP3 result in IPEX (immune dysregulation, polyendocrinopathy, enteropathy, X-linked) syndrome. Clinical presentation of IPEX syndrome is broader than initially described, challenging the understanding of the disease, its evolution, and treatment choice. OBJECTIVE We sought to study the type and extent of immunologic abnormalities that remain ill-defined in IPEX, across genetic and clinical heterogeneity. METHODS We performed Treg-cell-specific epigenetic quantification and immunologic characterization of severe "typical" (n = 6) and "atypical" or asymptomatic (n = 9) patients with IPEX. RESULTS Increased number of cells with Treg-cell-Specific Demethylated Region demethylation in FOXP3 is a consistent feature in patients with IPEX, with (1) highest values in those with typical IPEX, (2) increased values in subjects with pathogenic FOXP3 but still no symptoms, and (3) gradual increase over the course of disease progression. Large-scale profiling using Luminex identified plasma inflammatory signature of macrophage activation and TH2 polarization, with cytokines previously not associated with IPEX pathology, including CCL22, CCL17, CCL15, and IL-13, and the inflammatory markers TNF-α, IL-1A, IL-8, sFasL, and CXCL9. Similarly, both Treg-cell and Teff compartments, studied by Mass Cytometry by Time-Of-Flight, were skewed toward the TH2 compartment, especially in typical IPEX. CONCLUSIONS Elevated TSDR-demethylated cells, combined with elevation of plasmatic and cellular markers of a polarized type 2 inflammatory immune response, extends our understanding of IPEX diagnosis and heterogeneity.

Abstract
Finding cytokine storm initiator factors associated with uncontrolled inflammatory immune response is necessary in COVID-19 patients. The aim was the identification of Fas/Fas Ligand (FasL) role in lung involvement and mortality of COVID-19 patients. In this case-control study, mild (outpatient), moderate (hospitalized), and severe (ICU) COVID-19 patients and healthy subjects were investigated. RNA isolated from PBMCs for cDNA synthesis and expression of mFas/mFasL mRNA was evaluated by RT-PCR. Serum sFas/sFasL protein by ELISA and severity of lung involvement by CT-scan were evaluated. Also, we docked Fas and FasL via Bioinformatics software (in silico) to predict the best-fit Fas/FasL complex and performed molecular dynamics simulation (MDS) in hyponatremia and fever (COVID-19 patients), and healthy conditions. mFasL expression was increased in moderate and severe COVID-19 patients compared to the control group. Moreover, mFas expression showed an inverse correlation with myalgia symptom in COVID-19 patients. Elevation of sFasL protein in serum was associated with reduced lung injury and mortality. Bioinformatics analysis confirmed that blood profile alterations of COVID-19 patients, such as fever and hyponatremia could affect Fas/FasL complex interactions. Our translational findings showed that decreased sFasL is associated with lung involvement; severity and mortality in COVID-19 patients. We think that sFasL is a mediator of neutrophilia and lymphopenia in COVID-19. However, additional investigation is suggested. This is the first report describing that the serum sFasL protein is a severity and mortality prognostic marker for the clinical management of COVID-19 patients.

Abstract
The COVID-19 pandemic has challenged researchers to rapidly understand the capabilities of the SARS-CoV-2 virus and investigate potential therapeutics for SARS-CoV-2 infection. COVID-19 has been associated with devastating lung and cardiac injury, profound inflammation, and a heightened coagulopathic state, which may, in part, be driven by cellular crosstalk facilitated by extracellular vesicles (EVs). In recent years, EVs have emerged as important biomarkers of disease, and while extracellular vesicles may contribute to the spread of COVID-19 infection from one cell to the next, they also may be engineered to play a protective or therapeutic role as decoys or "delivery drivers" for therapeutic agents. This review explores these roles and areas for future study.

Abstract
Cell death plays a pivotal role in the maintenance of tissue homeostasis. Key players in the controlled induction of cell death are the Death Receptors (DR). CD95 is a prototypic DR activated by its cognate ligand CD95L triggering programmed cell death. As a consequence, alterations in the CD95/CD95L pathway have been involved in several disease conditions ranging from autoimmune diseases to inflammation and cancer. CD95L-induced cell death has multiple roles in the immune response since it constitutes one of the mechanisms by which cytotoxic lymphocytes kill their targets, but it is also involved in the process of turning off the immune response. Furthermore, beyond the canonical pro-death signals, CD95L, which can be membrane-bound or soluble, also induces non-apoptotic signaling that contributes to its tumor-promoting and pro-inflammatory roles. The intent of this review is to describe the role of CD95/CD95L in the pathophysiology of cancers, autoimmune diseases and chronic inflammation and to discuss recently patented and emerging therapeutic strategies that exploit/block the CD95/CD95L system in these diseases.

Diagnostic and prognostic significance of cell death markers in patients with cirrhosis and acute decompensation. PLoS One 2022; 17:e0263989.

Abstract
Background The transition from compensated to decompensated liver cirrhosis is a hallmark of disease progression, however, reliable predictors to assess the risk of decompensation in individual patients from routine diagnostics are lacking. Here, we characterize serum levels of cell death-associated markers and routine biochemistry from patients with chronic liver disease with and without decompensation. Methods A post-hoc analysis was based on prospectively collected clinical data from 160 patients with chronic liver disease, stably compensated or decompensated at baseline or during follow-up, over a median period of 721 days. Serum levels of damage-associated molecular patterns (DAMPs) and routine biochemistry are quantified at baseline (for all patients) and during follow-up (for patients with acute decompensation). The panel of DAMPs assessed in this study comprises high-mobility group-box protein 1 (HMGB1), cytochrome C (cyt C), soluble Fas-ligand (sFasL), interleukin 6 (IL-6), soluble cytokeratin-18 (CK18-M65) and its caspase‐cleaved fragment CK18-M30. Results In this cohort study, 80 patients (50%) were diagnosed with alcoholic liver cirrhosis, 60 patients (37.5%) with hepatitis C virus- and 20 patients (13.5%) with hepatitis B virus-related liver cirrhosis. At baseline, 17 patients (10.6%) showed decompensated liver disease and another 28 patients (17.5%) developed acute decompensation during follow-up (within 24 months). One hundred fifteen patients showed stable liver disease (71.9%). We found DAMPs significantly elevated in patients with decompensated liver disease versus compensated liver disease. Patients with acute decompensation during follow-up showed higher baseline levels of IL-6, sFasL, CK18-M65 and–M30 (P<0.01) compared to patients with stably compensated liver disease. In multivariate analyses, we found an independent association of baseline serum levels of sFasL (P = 0.02; OR = 2.67) and gamma-glutamyl transferase (GGT) (P<0.001; OR = 2.1) with acute decompensation. Accuracy of the marker combination for predicting acute decompensation was high (AUC = 0.79). Elevated aminotransferase levels did not correlate with decompensated liver disease and acute decompensation. Conclusions DAMPs are elevated in patients with decompensated liver disease and patients developing acute decompensation. The prognostic value of a marker combination with soluble Fas-ligand and GGT in patients with liver cirrhosis should be further evaluated.

Aging whole blood transcriptome reveals candidate genes for SARS-CoV-2-related vascular and immune alterations. J Mol Med (Berl) 2021; 100:285-301.

Abstract
Abstract The risk of severe COVID-19 increases with age as older patients are at highest risk. Thus, there is an urgent need to identify how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) interacts with blood components during aging. We investigated the whole blood transcriptome from the Genotype-Tissue Expression (GTEx) database to explore differentially expressed genes (DEGs) translated into proteins interacting with viral proteins during aging. From 22 DEGs in aged blood, FASLG, CTSW, CTSE, VCAM1, and BAG3 were associated with immune response, inflammation, cell component and adhesion, and platelet activation/aggregation. Males and females older than 50 years old overexpress FASLG, possibly inducing a hyperinflammatory cascade. The expression of cathepsins (CTSW and CTSE) and the anti-apoptotic co-chaperone molecule BAG3 also increased throughout aging in both genders. By exploring single-cell RNA-sequencing data from peripheral blood of SARS-CoV-2-infected patients, we found FASLG and CTSW expressed in natural killer cells and CD8 + T lymphocytes, whereas BAG3 was expressed mainly in CD4 + T cells, naive T cells, and CD14 + monocytes. In addition, T cell exhaustion was associated with increased expression of CCL4L2 and DUSP4 over blood aging. LAG3, PDCD1, TIGIT, VCAM1, HLA-DRA, and TOX also increased in individuals aged 60–69 years old; conversely, the RGS2 gene decreased with aging. We further identified a distinct gene expression profile associated with type I interferon signaling following blood aging. These results revealed changes in blood molecules potentially related to SARS-CoV-2 infection throughout aging, emphasizing them as therapeutic candidates for aggressive clinical manifestation of COVID-19. Key messages • Prediction of host-viral interactions in the whole blood transcriptome during aging. • Expression levels of FASLG, CTSW, CTSE, VCAM1, and BAG3 increase in aged blood. • Blood interactome reveals targets involved with immune response, inflammation, and blood clots. • SARS-CoV-2-infected patients with high viral load showed FASLG overexpression. • Gene expression profile associated with T cell exhaustion and type I interferon signaling were affected with blood aging.
