Unlike other herpesviruses, Epstein-Barr virus (EBV) has not yet been shown to infect macrophages. Six macrophage cultures were isolated from normal and affected samples. Nested polymerase chain reaction revealed the existence of the EBV genome in all these macrophages. EBV latent genes expression in all cultures were detected by mRNA in situ hybridization and immunofluorescence staining. Some cultures also expressed EBV replicative-infection proteins, while in other cultures induction of these proteins was demonstrated. These findings are the first to show expression of several latent and replicative-infection genes of EBV in macrophages, indicating that EBV proliferates in macrophages.

Tripartite organization of brain state dynamics underlying spoken narrative comprehension.

Speech comprehension involves the dynamic interplay of multiple cognitive processes, from basic sound perception, to linguistic encoding, and finally to complex semantic-conceptual interpretations. How the brain handles the diverse streams of information processing remains poorly understood. Applying Hidden Markov Modeling to fMRI data obtained during spoken narrative comprehension, we reveal that the whole brain networks predominantly oscillate within a tripartite latent state space.

Background: Osteoarthritis (OA) is one of the most common bone disorders and has a serious impact on the quality of life of patients. LncRNA-HCP5 (HCP5) is downregulated in OA tissues. However, the latent function and regulatory mechanisms of HCP5 in OA are unclear.

Extant models of health behaviour change often overlook stages in which individuals decide to partake in interventions. The current study aimed to identify behavioural and psychological factors that could capture a person's readiness to change a health behaviour and whether these could predict progression through stages of commitment. Rather than explicitly advertising a health behaviour intervention, we invited individuals to partake in a general health behaviour survey using a paid advertising campaign on Facebook (Phase 1).

Co-inhibitory molecules, such as cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell death protein 1 (PD-1), known as immune checkpoints, regulate the activity of T and myeloid cells during chronic viral infections and are well-established for their roles in cancer therapy. However, their involvement in chronic bacterial infections, particularly those caused by pathogens endemic to developing countries, such as Mycobacterium tuberculosis (Mtb), remains incompletely understood. Cytokine microenvironment determines the expression of co-inhibitory molecules in tuberculosis: Results indicate that the cytokine IL-12, in the presence of Mtb antigens, can enhance the expression of co-inhibitory molecules while preserving the effector and memory phenotypes of CD4+ T cells.

Clear cell renal cell carcinoma (ccRCC) is characterised by significant genetic heterogeneity, which has diagnostic and prognostic implications. Very limited evidence is available regarding DNA methylation heterogeneity. We therefore generate sequence level DNA methylation data on 136 multi-region tumour and normal kidney tissue from 18 ccRCC patients, along with matched whole exome sequencing (85 samples) and gene expression (47 samples) data on a subset of samples.
