AI Article Synopsis

  • We are creating effective techniques for gene transfer into tissue culture cells, using a combination of adenovirus and polylysine to enhance efficiency.
  • We previously demonstrated that a chimeric adenovirus-polylysine-reporter-gene complex could successfully transfer a transporter gene into HeLa cells with high efficiency.
  • Our latest methods involve simpler biochemical approaches that achieve nearly 100% transfection in various tissue culture cell lines, utilizing enzymatic coupling or biotin-streptavidin interactions to enhance the transfer process.

Article Abstract

We are developing efficient methods for gene transfer into tissue culture cells. We have previously shown that coupling of a chimeric adenovirus with polylysine allowed the construction of an adenovirus-polylysine-reporter-gene complex that transferred the transporter gene with great efficiency into HeLa cells. We have now explored simpler, biochemical means for coupling adenovirus to DNA/polylysine complexes and show that such complexes yield virtually 100% transfection in tissue culture cell lines. In these methods adenovirus is coupled to polylysine, either enzymatically through the action of transglutaminase or biochemically by biotinylating adenovirus and streptavidinylating the polylysine moiety. Combination complexes containing DNA, adenovirus-polylysine, and transferrin-polylysine have the capacity to transfer the reporter gene into adenovirus-receptor- and/or transferrin-receptor-rich cells.

Background: Autoimmune hepatitis (AIH) is a chronic liver inflammatory disease mediated by autoimmune reactions, the pathogenesis of AIH is probably related to the imbalance of intestinal flora. Yinchenhao decoction (YCHD) has been used to relieve AIH. However, the mechanisms underpinning YCHD's hepatoprotective effects with the gut microbito have not been fully revealed.

Respiratory Viral Infection Patterns in Hospitalised Children Before and After COVID-19 in Hong Kong.

Viruses

November 2024

Department of Paediatrics, Faculty of Medicine, The Chinese University of Hong Kong (CUHK), 6/F Lui Che Woo Clinical Sciences Building, Prince of Wales Hospital, Shatin, New Territories, Hong Kong, China.

Unlabelled: The study highlights the significant changes in respiratory virus epidemiology following the lifting of COVID-19 restrictions.

Method: In this single-centre retrospective study, the virological readouts of adenovirus (AdV), influenza virus A (IAV), influenza virus B (IBV), parainfluenza viruses (PIV) 1, 2, 3, 4, respiratory syncytial virus (RSV), and coupled enterovirus and rhinovirus (EV/RV) were extracted from the respiratory specimens of paediatric patients in Hong Kong from January 2015 to February 2024. The subjects were stratified into five age groups.

Article Synopsis
  • - The introduction of the non-native winter crane fly, Trichocera maculipennis, in maritime Antarctica may threaten the unique local ecosystem, which is vulnerable to foreign species.
  • - Researchers conducted tests using advanced methods to determine if T. maculipennis could mechanically transmit various viruses, and identified several human and plant virus genomic fragments in samples collected from the fly.
  • - Although the study found low amounts of human adenovirus and retrovirus in the fly samples, which were non-viable, it highlights the need for ongoing research into the impacts of non-native species on Antarctic ecosystems.

Clinical features and risk factors for development of post-infectious bronchiolitis obliterans in children.

BMC Pediatr

November 2024

Department of Respiratory Medicine, National Clinical Research Center of Respiratory Disease, Beijing Children's Hospital, Capital Medical University, National Center for Children's Health, NO.56, Nanlishi Road, Beijing, 100045, P. R. China.

Article Synopsis
  • Post-infectious bronchiolitis obliterans (PIBO) is a serious chronic lung disease in children that can develop after severe respiratory infections, and recognizing risk factors can enhance treatment options.
  • A study examined 308 children under five with PIBO and found high rates of ventilation use, co-infections, and a history of atopic conditions, with adenovirus often being a primary cause.
  • Further analysis indicated that co-infection, atopic conditions, and the length of fever are significant independent risk factors for developing PIBO following adenovirus pneumonia.

By coupling long-range polymerase chain reaction, wastewater-based epidemiology, and pathogen sequencing, we show that adenovirus type 41 hexon-sequence lineages, described in children with hepatitis of unknown origin in the United States in 2021, were already circulating within the country in 2019. We also observed other lineages in the wastewater, whose complete genomes have yet to be documented from clinical samples.
