PROBLEM: Herpes simplex virus 1 (HSV-1) commonly causes orolabial infection, but can also infect the genital mucosa. In contrast, HSV-2 is usually genital. Genital herpes can transmit the virus vertically to the fetus during pregnancy. We sought to estimate the prevalence of HSV-1/2 on the maternal and fetal sides of the placenta. METHOD OF STUDY: Placental tissues were collected from pregnant women seen at the Rio Grande University Hospital. HSV-1 and HSV-2 were detected by nested PCR...

Herpes B virus (BV, Macacine alphaherpesvirus 1) infects macaques asymptomatically, with rare exceptions, but can cause fatal encephalitis in humans. Here, we report disseminated BV infection in a cynomolgus macaque that had died within 12 hour after the onset of unspecific symptoms. Multifocal lesions surrounded by viral antigen were detected in liver while other organs remained inconspicuous, indicating that the liver is a major target. Moreover, high copy numbers of viral DNA were found in feces, underlining the excrements are a potential source of transmission...

BACKGROUND: Factors contributing to elevated inflammation in racial/ethnic minority populations are not well understood. We examined the association of viral exposure with C-reactive protein (CRP) in young Mexican American women. METHODS AND RESULTS: Participants (N=1,141) were currently non-pregnant women of Mexican background, aged 18-39 years, from the cross-sectional National Health and Nutrition Examination Survey (NHANES) 1999-2010. Viral exposure was defined as seropositive status for hepatitis B, and herpes simplex types 1 and 2, and classified as seronegative, seropositive for any one agent, and seropositive for 2 or 3 agents...

Re-exposure to chickenpox may boost varicella-zoster virus (VZV) immunity in the elderly. This secondary immune response is hypothesized to confer protection against herpes zoster. We longitudinally sampled 36 adults over the course of one year after re-exposure to chickenpox. The resulting 183 samples and those of 14 controls were assessed for VZV-specific T-cell immunity and antibody titres. The percentages of VZV-specific CD4+ IL-2-producing T-cells were increased in re-exposed grandparents compared to control participants up to 9 months after re-exposure...

Nuclear domain 10 (ND10) bodies are small (0.1-1 μM) nuclear structures containing both constant [e.g., promyelocytic leukemia protein (PML), SP100, death domain-associated protein (Daxx)] and variable proteins, depending on the function of the cells or the stress to which they are exposed. In herpes simplex virus (HSV)-infected cells, ND10 bodies assemble at the sites of DNA entering the nucleus after infection. In sequence, the ND10 bodies become viral replication compartments, and ICP0, a viral E3 ligase, degrades both PML and SP100...

Lectins are ubiquitous proteins/glycoproteins of non-immune origin that bind reversibly to carbohydrates in non-covalent and highly specific manner. These lectin-glycan interactions could be exploited for establishment of novel therapeutics, targeting the adherence stage of viruses and thus helpful in eliminating wide spread viral infections. Here the review focuses on the haemagglutination activity, carbohydrate specificity and characteristics of cyanobacterial lectins. Cyanobacterial lectins exhibiting high specificity towards mannose or complex glycans have potential role as anti-viral agents...

Senescent cells (SnCs) accumulate in many vertebrate tissues with age and contribute to age-related pathologies, presumably through their secretion of factors contributing to the senescence-associated secretory phenotype (SASP). Removal of SnCs delays several pathologies and increases healthy lifespan. Aging and trauma are risk factors for the development of osteoarthritis (OA), a chronic disease characterized by degeneration of articular cartilage leading to pain and physical disability. Senescent chondrocytes are found in cartilage tissue isolated from patients undergoing joint replacement surgery, yet their role in disease pathogenesis is unknown...

The use of quantum dots (QDs) for nanomedicine is hampered by their potential toxicologic effects and difficulties with delivery into the cell interior. We accomplished an in vivo study exploiting Daphnia magna and Xenopus laevis to evaluate both toxicity and uptake of QDs coated with the membranotropic peptide gH625 derived from the glycoprotein H of herpes simplex virus and widely used for drug delivery studies. We evaluated and compared the effects of QDs and gH625-QDs on the survival, uptake, induction of several responsive pathways and genotoxicity in D...

Lysosomes play vital roles in both innate and adaptive immunity. It is widely accepted that lysosomes do not function exclusively as a digestive organelle. It is also involved in the process of immune cells against pathogens. However, the changes in the lysosomal proteome caused by infection with various microbes are still largely unknown, and our understanding of the proteome of the purified lysosome is another obstacle that needs to be resolved. Here, we performed a proteomic study on lysosomes enriched from THP1 cells after infection with Listeria monocytogenes (L...

Duck enteritis virus (DEV) UL54 is a homologue of human herpes simplex virus-1 (HSV-1) ICP27, which plays essential regulatory roles during infection. Our previous studies indicated that DEV UL54 is an immediate-early protein that can shuttle between the nucleus and the cytoplasm. In the present study, we found that UL54-deleted DEV (DEV-ΔUL54) exhibits growth kinetics, a plaque size and a viral DNA copy number that are significantly different from those of its parent wild-type virus (DEV-LoxP) and the revertant (DEV-ΔUL54 (Revertant))...

The herpes simplex virus (HSV) diseases represent a relevant medical and social problem due to their communicability and recurrence following latency. The green algae are rich source of polysaccharides referred to as ulvans, reported as being biologically and pharmacologically active. In this work, we analyzed the activity of seven chemically modified polysaccharides from Enteromorpha compressa (Chlorophyta, Ulvaceae), against HSV. Only the derivative named SU1F1 showed satisfactory viral inhibition activity, with a high selectivity index, and, therefore, it was submitted to analysis of the probable mechanism of action and structure...
