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.

CRISPR-Cas9 has emerged as a highly effective and customizable genome editing tool, holding significant promise for the treatment of KRAS mutations in lung cancer. In this study, we introduce a novel micelleplex, named C14-PEI, designed to co-deliver Cas9 mRNA and sgRNA efficiently to excise the mutated KRAS allele in lung cancer cells. C14-PEI is synthesised from 1,2-epoxytetradecane and branched PEI 600 Da a ring-opening reaction.

Merkel cell carcinoma (MCC) is a rare but aggressive neuroendocrine skin cancer with limited treatment options, often associated with Merkel cell polyomavirus (MCPyV) and marked by hypoxic tumor microenvironments that promote resistance to therapies. Belzutifan, an FDA-approved hypoxia-inducible factor-2α (HIF-2α) inhibitor, has shown promise in inhibiting tumor growth; however, its clinical efficacy is hindered by its low solubility, rapid clearance, and limited bioavailability. In this study, we present a strategy using porous silicon (pSi) microparticles and nanoparticles as carriers for the sustained delivery of benzoate to MCC cells.

It is well known that clonal integration of the Merkel cell polyomavirus into the dermal precursor cells is a hypothesized pathway in Merkel cell carcinoma pathogenesis. Here, we demonstrate a case of Merkel cell carcinoma (primary origin unknown) presenting with high Merkel cell polyomavirus DNA levels in swabs obtained from normal skin.

Merkel cell carcinoma (MCC) is an uncommon aggressive neoplasm, usually arising in sun-exposed skin of the head and neck. By immunohistochemistry, KRT20 and MCPyV positivity are found in about 90% and 80% of MCCs, respectively. Noteworthy, viral status in lip/oral cavity MCCs is poorly known.
