BACKGROUND: Severe myocarditis is often accompanied by cardiac fibrosis, but the underlying mechanism has not been fully elucidated. CXCL4 is a chemokine that has been reported to have pro-inflammatory and profibrotic functions. The exact role of CXCL4 in cardiac fibrosis remains unclear. METHODS: Viral myocarditis (VMC) models were induced by intraperitoneal injection of Coxsackie B Type 3 (CVB3). In vivo, CVB3 (100 TCID50) and CVB3-AMG487 (CVB3: 100 TCID50; AMG487: 5 mg/kg) combination were administered in the VMC and VMC+AMG487 groups, respectively...

Virus-related illnesses are a common phenomenon, especially in the colder months of the year. They usually manifest with cough, cold, and other flu-associated symptoms. They affect people of all ages and genders. In recent years, also virus-associated ocular symptoms have been documented repeatedly. One of the viruses known to cause these is the Coxsackievirus A, which causes hand, foot, and mouth disease. Three cases of these virus-associated macular changes are described below. In all three cases, the symptoms occurred unilaterally and with little time delay to the virus-typical general changes...

INTRODUCTION: In rare occasions, coxsackievirus infections can cause serious illness, such as encephalitis and myocarditis. The immunotherapies of cancer could increase the risk of myocarditis, especially when applying immune checkpoint inhibitors. Herein, we report a rare case of Coxsackie B virus-induced myocarditis in a patient with a history of lymphoma. CASE PRESENTATION: A 32-year-old woman was admitted to the hospital with recurrent fever for more than 20 days, and she had a history of lymphoma...

BACKGROUND: Kaposi Varicelliform Eruptions (KVE), also known as eczema herpeticum, is a rare and potentially life-threatening dermatological condition primarily attributed to herpes simplex virus (HSV) infection, with less frequent involvement of Coxsackie A16, vaccinia, Varicella Zoster, and smallpox viruses. Typically associated with pre-existing skin diseases, especially atopic dermatitis, KVE predominantly affects children but can manifest in healthy adults. Characterized by painful clusters of vesicles and sores on the skin and mucous membranes, it often masquerades as other dermatological disorders...

Bone and soft-tissue sarcomas are rare malignancies with histological diversity and tumor heterogeneity, leading to the lack of a common molecular target. Telomerase is a key enzyme for keeping the telomere length and human telomerase reverse transcriptase (hTERT) expression is often activated in most human cancers, including bone and soft-tissue sarcomas. For targeting of telomerase-positive tumor cells, we developed OBP-301, a telomerase-specific replication-competent oncolytic adenovirus, in which the hTERT promoter regulates adenoviral E1 gene for tumor-specific viral replication...

AIMS/HYPOTHESIS: Infection with coxsackie B viruses (CVBs) can cause diseases ranging from mild common cold-type symptoms to severe life-threatening conditions. CVB infections are considered to be prime candidates for environmental triggers of type 1 diabetes. This, together with the significant disease burden of acute CVB infections and their association with chronic diseases other than diabetes, has prompted the development of human CVB vaccines. The current study evaluated the safety and immunogenicity of the first human vaccine designed against CVBs associated with type 1 diabetes in a double-blind randomised placebo-controlled Phase I trial...

OBJECTIVES: Neonatal myocarditis is a rare but life-threatening complication of enterovirus infection that presents like bacterial sepsis. OUTBREAK: A sudden upsurge in cases of neonatal enteroviral myocarditis, reported from South West England and South Wales between June 2022 and April 2023 has alerted health agencies to bring in counteracting measures. IMPACT: In view of this outbreak situation, the World Health Organisation advisory has urged clinicians seeing neonates and infants with shock may consider myocarditis as a differential diagnosis and test for enteroviruses...

Recently, we identified the coxsackie and adenovirus receptor (CAR) as the entry receptor for rhesus enteric calicivirus (ReCV) isolate FT285 and demonstrated that co-expression of the CAR and the type B histo-blood group antigen (HBGA) is required to convert the resistant CHO cell line susceptible to infection. To address whether the CAR is also the functional entry receptor for other ReCV isolates and the requirement for specific HBGAs or other glycans, here we used a panel of recombinant CHO cell lines expressing the CAR and the type A, B, or H HBGAs alone or in combination...

Adenovirus (AdV) infection of the respiratory epithelium is common but poorly understood. Human AdV species C types, such as HAdV-C5, utilize the Coxsackie-adenovirus receptor (CAR) for attachment and subsequently integrins for entry. CAR and integrins are however located deep within the tight junctions in the mucosa where they would not be easily accessible. Recently, a model for CAR-independent AdV entry was proposed. In this model, human lactoferrin (hLF), an innate immune protein, aids the viral uptake into epithelial cells by mediating interactions between the major capsid protein, hexon, and yet unknown host cellular receptor(s)...

Endometriosis is a benign high prevalent disease exhibiting malignant features. However, the underlying pathogenesis and key molecules of endometriosis remain unclear. By integrating and analysis of existing expression profile datasets, we identified coxsackie and adenovirus receptor (CXADR), as a novel key gene in endometriosis. Based on the results of immunohistochemistry (IHC), we confirmed significant down-regulation of CXADR in ectopic endometrial tissues obtained from women with endometriosis compared with healthy controls...

The Eucalyptus tree, belonging to the myrtle family, grows all over the world for its pharmaceutical and industrial benefits. In this article, we present a comparative analysis of the chemical composition of the hydrodistilled oils obtained from three different Eucalyptus species growing in Egypt viz. E. citriodora , E. camaldulensis , and E. ficifolia . Gas Chromatography-Mass Spectrometric guided analysis resulted in the identification of a total of 20 metabolites in E. citriodora oil with citronellal (54...

Enteroviral infections have been linked to the development of islet autoimmunity (IA) and type 1 diabetes (T1D), and the coxsackie and adenovirus receptor (CXADR) is one of the ligands used by adenoviruses and enteroviruses for cell internalization. Two CXADR single nucleotide polymorphisms (SNPs), rs6517774 and rs2824404, were previously associated with an increased susceptibility to IA in the international TEDDY study (The Environmental Determinants of Diabetes in the Young). This study aimed to replicate the results by genotyping 2886 children enrolled in the Finnish Diabetes Prediction and Prevention study (DIPP)...

The clinical association between Coxsackievirus B (CVB) and methicillin-sensitive Staphylococcus aureus (MSSA) has not been well established in the current literature. Here, we report a case of a 29-year-old male who presented with fever and malaise 24 hours after noticing a pruritic lesion on the anterior foreleg that resembled a mosquito bite. After multiple ED visits, laboratory studies, and imaging tests, the patient was admitted for treatment of high fevers and pancytopenia. The final diagnosis was viral sepsis complicated by co-infection with MSSA...

In the past, histological diagnosis of (post-)viral myocarditis was based on the so-called Dallas criteria, which have been criticized because of high interobserver variability and sampling error. Immunohistochemical qualification and quantification of interstitial intramyocardial leucocytes was established and standard values concerning adults were published. Fatal casualties due to a viral myocarditis are rare as far as babies and children are concerned (sudden unexpected death in infancy; SUDI). Cases of sudden unexpected death in the first year of life are frequently regarded as sudden infant death syndrome (SIDS)...

Objective: This study was aimed to describe the clinical features and outcomes of Omicron-associated croup in children. Methods: A total of 105 children aged 3-60 months (median age 11 months) with coronavirus disease 2019 (COVID-19) and cough were admitted to our hospital from December 16, 2022, to December 31, 2022. Their clinical features, treatment, and outcomes were reviewed. These children were followed up for 8 months. Results: Among the cases, 5 had complex medical histories, while the other children were generally healthy...

Human adenoviruses represent attractive candidates for the design of cancer gene therapy vectors. Modification of adenovirus tropism by incorporating a targeting ligand into the adenovirus capsid proteins allows retargeting of adenovirus towards the cells of interest. Human adenovirus type 5 (HAdV-C5) bearing NGR containing peptide (CNGRCVSGCAGRC) inserted into the fiber (AdFNGR) or the hexon (AdHNGR) protein demonstrated an increased transduction of endothelial cells showing expression of aminopeptidase N, also known as CD13, and αvβ3 integrin both present on tumor vasculature, indicating that NGR-bearing adenoviruses could be used as tools for anti-angiogenic cancer therapy...

Holoptelea integrifolia , also known as the Indian Elm Tree, has been used in Ayurvedic medicine for its medicinal properties. In this study, two biologically active metabolites, 5(6) dihydrostigmast 22en 3- O -β-glucoside (DHS) and 1- O -eicosanoyl glycerol-2'- O -β-galactouronic (EGG), were isolated for the first time from the n -butanol fraction of H. integrifolia using a chromatographic technique and identified by NMR, and HRESI-MS. The antiviral and multidrug-resistant activities of these metabolites were evaluated as well as the n -butanol fraction...
