In light of the scarcity of reports on the interaction between HSV-1 nucleocapsid protein UL25 and its host cell proteins, the purpose of this study is to use yeast two-hybrid screening to search for cellular proteins that can interact with the UL25 protein. C9orf69, a protein of unknown function was identified. The interaction between the two proteins under physiological conditions was also confirmed by biological experiments including co-localization by fluorescence and immunoprecipitation. A preliminary study of the function of C9orf69 showed that it promotes viral proliferation. Further studies showed that C9orf69 did not influence viral multiplication efficiency by transcriptional regulation of viral genes, but indirectly promoted proliferation via interaction with UL25.

Gammaherpesviruses are DNA tumor viruses that establish lifelong latent infections in lymphocytes. For viruses such as Epstein-Barr virus and murine gammaherpesvirus 68, this is accomplished through a viral gene-expression program that promotes cellular proliferation and differentiation, especially of germinal center B cells. Intrinsic host mechanisms that control virus-driven cellular expansion are incompletely defined.

Fungal spores are abundant in the environment and a major cause of asthma. Originally characterised as a type 2 inflammatory disease, allergic airway inflammation that underpins asthma can also involve type 17 inflammation, which can exacerbate disease causing failure of treatments tailored to inhibit type 2 factors. However, the mechanisms that determine the host response to fungi, which can trigger both type 2 and type 17 inflammation in allergic airway disease, remain unclear.

Antimicrobial resistance (AMR) is a pandemic spread across multiple infectious disease-causing microbes. To provide a host-specific tool to study antibiotic susceptibility and resistance, here we develop Klebsiella pneumoniae cell-free gene expression (CFE) systems from laboratory and clinical isolates. Using proteomics, we identify relative differences and unique proteins for these new CFE systems in comparison to an Escherichia coli MG1655 CFE model.

Host metabolic fitness is a critical determinant of infectious disease outcomes. Obesity, aging, and other related metabolic disorders are recognized as high-risk disease modifiers for respiratory infections, including coronavirus infections, though the underlying mechanisms remain unknown. Our study highlights fatty acid-binding protein 4 (FABP4), a key regulator of metabolic dysfunction and inflammation, as a modulator of SARS-CoV-2 pathogenesis, correlating strongly with disease severity in COVID-19 patients.

Vulvovaginal candidiasis (VVC) is one of the most common infections caused by . VVC is characterized by an inadequate hyperinflammatory response and clinical symptoms associated with colonization of the vaginal mucosa. Compared to other host niches in which can cause infection, the vaginal environment is extremely rich in lactic acid that is produced by the vaginal microbiota.
