Unlabelled: Respiratory and encephalitic virus infections represent a significant risk to public health globally. Detailed investigations of immunological responses and disease outcomes during sequential virus infections are rare. Here, we define the impact of influenza virus infection on a subsequent virus encephalitis.

The molecular mechanisms by which vaccinia virus (VACV), the prototypical member of the poxviridae family, reprograms host cell metabolism remain largely unexplored. Additionally, cells sense and respond to fluctuating nutrient availability, thereby modulating metabolic pathways to ensure cellular homeostasis. Understanding how VACV modulates metabolic pathways in response to nutrient signals is crucial for understanding viral replication mechanisms, with the potential for developing antiviral therapies.

Further understanding of the molecular mediators of alternative RBC invasion phenotypes in endemic malaria parasites will support malaria blood-stage vaccine or drug development. This study investigated the prevalence of sialic acid (SA)-dependent and SA-independent RBC invasion pathways in endemic parasites from Cameroon and compared the schizont stage transcriptomes in these two groups to uncover the wider repertoire of transcriptional variation associated with the use of alternative RBC invasion pathway phenotypes. A two-color flow cytometry-based invasion-inhibition assay against RBCs treated with neuraminidase, trypsin, and chymotrypsin and deep RNA sequencing of schizont stages harvested in the first replication cycle in culture were employed in this investigation.

Background: Akabane virus (AKAV) is an arthropod-borne virus that causes congenital malformations and neuropathology in cattle and sheep. In South Korea, AKAVs are classified into two main genogroups: K0505 and AKAV-7 strains. The K0505 strain infects pregnant cattle, leading to fetal abnormalities, while the AKAV-7 strain induces encephalomyelitis in post-natal cattle.

Since cartilage injury is often accompanied by subchondral bone damage, conventional single-phase materials cannot accurately simulate the osteochondral structure or repair osteochondral injury. In this work, a gradient gelatin-methacryloyl (GelMA) hydrogel scaffold was constructed by a layer-by-layer stacking method to realize full-thickness regeneration of cartilage, calcified cartilage and subchondral bone. Of note, to surmount the inadequate mechanical property of GelMA hydrogel, nanohydroxyapatite (nHA) was incorporated and further functionalized with hydroxyethyl methacrylate (nHA-hydroxyethyl methacrylate, nHAMA) to enhance the interfacial adhesion with the hydrogel, resulting in better mechanical strength akin to human bone.
