The aim of this study was to investigate the presence of Herpes simplex virus (HSV) type 1 and type 2 DNA from the clinical samples sent to our routine laboratory, by real-time polymerase chain reaction (PCR). A total of 328 samples collected from 306 female and 7 male patients who were admitted to different outpatient clinics were included in the study. The samples included 235 cervical swab samples (of which 150 were from pregnant women), 77 amniotic fluid, 8 blood, 6 cerebrospinal fluid (CSF), one pericardial fluid and one cervical biopsy. DNA extraction were performed with High Pure Viral Nucleic Acid Kit (Roche, Germany) and amplified in Light Cycler (Roche, Germany) with a commercial amplification mix (Metis Biotechnology, Ankara). HSV-DNA positivity were found in 2.1% of the cervical samples (three of 150 pregnant and two of 85 non-pregnant women), two of the blood samples and one of the CSF sample, while there were no positive result for the other clinical specimens. It can be concluded that, real-time PCR would be preferred in conditions requiring rapid diagnosis such as HSV infections of central nervous system and HSV suspected infections of immunosupressed patients, as a rapid and practical method.

Herpes simplex keratitis (HSK) is a prevalent infectious corneal disorder. This study aims to explore the role of plasmacytoid dendritic cells (pDCs) in HSK, an area that remains underexplored. The investigation centers on the effects of a STAT1 transcription enhancer, 2-NP, on pDCs and its underlying mechanisms.

Background: Herpes simplex virus type 2 (HSV-2) is a common sexually transmitted infection (STI) primarily acquired through sexual contact. In 2000, the World Health Organization (WHO) for the first time reported the association of STIs with male infertility. Infertility is described as the inability to achieve a clinical pregnancy after engaging in regular, unprotected sexual intercourse for a year or more.

Alzheimer's disease (AD) diagnosis relies on the presence of extracellular β-amyloid (Aβ) and intracellular hyperphosphorylated tau (p-tau). Emerging evidence suggests a potential link between AD pathologies and infectious agents, with herpes simplex virus 1 (HSV-1) being a leading candidate. Our investigation, using metagenomics, mass spectrometry, western blotting, and decrowding expansion pathology, detects HSV-1-associated proteins in human brain samples.

Background: Early Onset Alzheimer's Disease (EOAD) is thought to result from a combination of environmental, genetic, and lifestyle factors. Herpesvirus infections may contribute to the development of EOAD and the objective of our study is to identify potential associations between herpes virus infections and the risk of developing EOAD.
Method: Amyloid-status Alzheimer's disease was diagnosed based on clinical history and ATN criteria, determined by the measuring the Amyloidß42:40 ratio, tau, and 181-Phospho-tau in the cerebrospinal fluid.
Background: Millions of people suffer from traumatic brain injury (TBI) annually and many subsequently develop AD-like characteristics, but the processes occurring in the brain and the reasons for the acquisition of AD-like dementia are unknown. TBI is the leading cause of mortality in young adults and causes a huge socioeconomic burden. Improving outcomes in these patients would be a significant public health benefit.
