Vacuolated Parabasal Cells in Papanicolaou Smears Are Cellular Changes Caused by Human Papillomavirus 16 Infection.

In cervical cancer screening, cytology is used as a triage test to refer high-risk human papillomavirus (HR-HPV)-positive women for colposcopy, but its accuracy is inadequate. The present study aimed to demonstrate that the presence of atypical cells with large vacuoles in the cytoplasm of parabasal cells, referred to as vacuolated parabasal cells (VPCs), which are observed in the Pap smears of HPV-positive women, is associated with specific HPV genotypes. Among 2175 patients, 310 with a single HR-HPV infection and cytological diagnosis of high-grade squamous intraepithelial lesions (HSIL) or atypical squamous cells not excluding HSIL (ASC-H) were included, of which 86 were infected with HPV16.

The bovine leukemia virus (BLV) is a pathogen of high importance for the dairy industry. Currently, twelve genotypes have been described worldwide with different pathogenicity and virulence, so it is critical to evaluate the circulating genotypes in each country/region to associate this information with risk situations. The aim of this work was to perform a phylogenetic and mutational analysis of the BLV tax gene in cows that belong to specialized dairies in the Department of Antioquia, Colombia.

Department of Critical Care Medicine, The Eighth Medical Center of Chinese PLA General Hospital, Beijing, China.
Background: The roles of the Pink1/Parkin pathway and mitophagy in lung injury during heat stroke remain unclear. In this study, we investigated the role of Pink1/Parkin-mediated mitophagy in acute lung injury (ALI) in rats with exertional heat stroke (EHS).
Methods: Sixty Sprague Dawley rats were randomly divided into control (CON), control + Parkin overexpression (CON + Parkin), EHS, and EHS + Parkin overexpression (EHS + Parkin) groups.
Identification of Epinastine as CD96/PVR inhibitor for cancer immunotherapy.

School of Life Sciences, Zhengzhou University, Zhengzhou, 450001, China.
Background: Poliovirus receptor (PVR) and its receptor system, including TIGIT, CD226, and CD96, play a pivotal role in orchestrating tumor immune evasion. Upon engagement with PVR on tumor cells, CD96 exerts inhibitory effects on the function of T cells and NK cells, thereby fostering tumor immune evasion. Therefore, screening of immune checkpoint inhibitors (ICIs) targeting the CD96/PVR pathway will provide promising candidates for tumor immunotherapy.

Background: Oncolytic viruses (OVs) are promising immunotherapeutics to treat immunologically cold tumors. However, research on the mechanism of action of OVs in humans and clinically relevant biomarkers is still sparse. To induce strong T-cell responses against solid tumors, TILT-123 (Ad5/3-E2F-d24-hTNFa-IRES-hIL2, igrelimogene litadenorepvec) was developed.
