Electron microscopy (EM), real-time polymerase chain reaction (PCR) and conventional PCR were used to identify viruses associated with infection in 2 transplantation patients. An autologous haematopoietic stem cell, liver and renal transplant recipient was found to be positive for simian virus 40 (SV40). Dual BK virus and SV40 infection was found in a heart and renal transplantation patient. SV40 infection can occur in immunocompromised patients.

Background: Mitochondrial dysfunction and damage can result in the release of mitochondrial DNA (mtDNA) into the cytoplasm, which subsequently activates the cGAS-STING pathway, promoting the onset of inflammatory diseases. Various factors, such as oxidative stress, viral infection, and drug toxicity, have been identified as inducers of mitochondrial damage. This study aims to investigate the role of mtDNA as a critical inflammatory mediator in the pathogenesis of ketamine (KET)-induced cystitis (KC) through the cGAS-STING pathway.

Broadly neutralizing antibodies (bnAbs) against HIV-1 have been shown to protect from systemic infection. When employing a novel challenge virus that uses HIV-1 Env for entry into target cells during the first replication cycle, but then switches to SIV Env usage, we demonstrated that bnAbs also prevented mucosal infection of the first cells. However, it remained unclear whether antibody Fc-effector functions contribute to this sterilizing immunity.

The low knock-in efficiency, especially in primary human cells, limits the use of the genome editing technology for therapeutic purposes, rendering it important to develop approaches for increasing the knock-in levels. In this work, the efficiencies of several approaches were studied using a model of knock-in of a construct coding for the peptide HIV fusion inhibitor MT-C34 into the human CXCR4 locus in the CEM/R5 T cell line. First, donor DNA modification was evaluated as a means to improve the efficiency of plasmid transport into the nucleus.

We obtained the near-complete simian foamy virus (SFV) genome from an infected human bitten by an African green monkey ( SFVcae_hu501). The genome is 13,062 nucleotides long with the classical SFV genome structure. Phylogenetically, SFVcae_hu501 clustered closely with SFV from (SFVagm_LK3).

Objectives: Oral cancer (OC) is the most common malignant tumor of the head and neck (HN) and ranks 16th among the most frequently diagnosed cancers worldwide. A systematic review and meta-analysis aimed to provide an evidence-based analysis of the relationship between polyomaviruses and oral cancer.
Methods: The global online databases was used to identify relevant studies published between January 2000 and September 2024.
