Extended receptor repertoire of an adenovirus associated with human obesity.
PLoS Pathog
January 2025
Department of Clinical Microbiology, Umeå University, Umeå, Sweden.
Human adenovirus type 36 (HAdV-D36) has been putatively linked to obesity in animals and has been associated with obesity in humans in some but not all studies. Despite extensive epidemiological research there is limited information about its receptor profile. We investigated the receptor portfolio of HAdV-D36 using a combined structural biology and virology approach.

Dokl Biochem Biophys
January 2025
Engelhardt Institute of Molecular Biology, Russian Academy of Sciences, Moscow, Russia.
In this work, two new compounds, N-(4,5-dimethoxyphenyl)adenine and N-(3,5-di-trifluoromethylphenyl)adenine, with a broad range of antiviral activity against RNA viruses were identified. We showed that these compounds exhibit pronounced antiviral activity against human poliovirus types 1, 2, and 3, belonging to enterovirus C species. Both compounds also demonstrated pronounced antiviral activity against Coxsackie viruses B3, B5, and B6, belonging to enterovirus B species.

Department of Ophthalmology, Stanley M. Truhlsen Eye Institute, University of Nebraska Medical Center, Omaha, NE, USA.
Purpose: To describe a rare case of presumed bilateral acute idiopathic maculopathy (AIM) in a pediatric patient.
Observation: An 11-year-old male was evaluated for a "fuzzy Dorito-shaped" spot in the central vision of his right eye (OD) that started 3 days before presenting to our clinic. On examination, best-corrected visual acuity (BCVA) was counting fingers at 5 feet OD, and 20/25 in the left eye (OS).
Ajwa date extract (): Phytochemical analysis, antiviral activity against herpes simplex virus-I and coxsackie B4 virus, and in silico study.

Objectives: To investigate the phytochemical composition of Ajwa date extract and evaluate its antiviral activity and mechanism of action.
Methods: High perfomance liquid chromatography, gas chromatography-mass spectrometry, and liquid chromatography-mass spectrometry were used to analyze the phytochemical profile of Ajwa date extract. The antiviral activity was assessed using the MTT colorimetric assay against herpes simplex virus type I (HSV-I) and coxsackievirus B4 (CVB-4).
Persistent Rhesus Enteric Calicivirus Infection in Recombinant CHO Cells Expressing the Coxsackie and Adenovirus Receptor.
Viruses
November 2024
Department of Veterinary Pathobiology, College of Veterinary Medicine & Biomedical Sciences, Texas A&M University, College Station, TX 77843, USA.
Recently, using a panel of recombinant CHO cell lines, we identified the coxsackie and adenovirus receptor (CAR) and histo-blood group antigens (HBGAs) or sialic acid as the minimum requirement for susceptibility to rhesus enteric calicivirus (ReCV) infections. While ReCVs cause lytic infection in LLC-MK2 cells, recombinant CHO (rCHO) cell lines did not exhibit any morphological changes upon infection. To monitor infectious virus production, rCHO cell cultures had to be freeze-thawed and titrated on LLC-MK2 monolayers.
