A single-nucleotide polymorphism (SNP) in the promoter region of MDM2 (SNP309T>G, rs2279744) has been shown to increase the expression of the MDM2 protein in various cancer types. However, only one study has analyzed the role of the MDM2 polymorphism in the development of Kaposi's sarcoma (KS). The association of MDM2 SNP309 with classic KS risk was evaluated in 79 Iranian patients with classic KS and 123 healthy controls. The MDM2 SNP309 was genotyped using PCR and restriction fragment length polymorphism methods...

We previously reported a pair of H5N1 avian influenza viruses which are genetically similar but differ greatly in their virulence in mice. A/Chicken/Jiangsu/k0402/2010 (CK10) is highly lethal to mice, whereas A/Goose/Jiangsu/k0403/2010 (GS10) is avirulent. In this study, to investigate the host factors that account for their virulence discrepancy, we compared the pathology and host proteome of the CK10- or GS10-infected mouse lung. Moderate lung injury was observed from CK10-infected animals as early as the first day of infection, and the pathology steadily progressed at later time point...

Paracoccidioides brasiliensis is one of the etiological agents of the human systemic mycosis paracoccidioidomycosis. Protease-activated receptors (PARs) are expressed in many cell types and comprise a family of G protein-coupled receptors (PAR-1, PAR-2, and PAR-4), which may be activated by proteases secreted by several pathogens. In the present study, we showed that the pathogenic fungus P. brasiliensis secretes components that promote interleukin (IL)-6 and IL-8 secretion by the lung epithelial cell line A549...

Infection with Burkholderia cepacia complex (Bcc) bacteria is a threat to cystic fibrosis (CF) patients, commonly leading to a fatal pneumonia, the cepacia syndrome. It causes a massive production of pro-inflammatory cytokines and leucocyte recruitment to airway epithelium without resolving infection and contributing to tissue lesion. To dissect how Bcc bacteria subvert the immune response, we developed a co-culture model with human dendritic cells (DCs) and B. cenocepacia clonal variants isolated from a chronically infected CF patient, who died with cepacia syndrome...

The assessment of the gender and age-specific seroprevalence of human papillomavirus (HPV) is essential for planning of HPV vaccine implementation into the preventive programs. In this study, we aimed to determine the age-specific seroprevalence of HPV-16 and 18 in both males and females in Tehran, Iran. Three hundred and seventy-eight women (10-35 years) and 162 men (10-25 years) from Tehran, Iran, were enrolled. Anti-HPV IgG antibodies against HPV-16 and HPV-18 were detected by ELISA using papillomavirus type 16 and 18 L1-capsids as antigen...

Human papillomaviruses (HPVs) are an acknowledged cause of a subset of oropharyngeal cancers, especially of tonsillar cancer. Similar to HPV, some human polyomaviruses (HPyVs), such as Merkel cell polyomavirus (MCPyV), have an oncogenic potential. Recently, several novel HPyVs have been discovered. The aim of our study was to determine viral DNA prevalence and viral DNA load of 13 different HPyVs in benign and malignant tonsillar tissue and to compare the data with those found for HPV. A total of 78 biopsies of palatine tonsils with a histologic diagnosis of non-malignant disease (chronic tonsillitis, tonsillar hyperplasia, n = 40) or tonsillar squamous cell carcinoma (n = 38) were included in the study...

Infections continue to be one of the leading causes of morbidity and mortality in liver transplant recipients. We retrospectively reviewed the symptomatic infectious episodes that occurred during the first year post-transplant to determine time of onset, causative pathogens and cell-mediated immunity response patterns. Ninety-eight of the 202 (48.5%) recipients enrolled developed at least one infectious episode. The total number of infectious episodes was 135: 77 (57.1%) bacterial, 45 (33.3%) viral and 13 (9...

Data about the prevalence of human papillomaviruses (HPV) in African women with normal and abnormal cervical cytology are still scarce. Current HPV vaccines contain HPV types, which mainly represent the HPV epidemiology of industrial countries. As further developments of HPV vaccines are going on, it is necessary to regard regional differences in HPV type prevalence to ensure optimal protection by the vaccine. Vaginal swabs of Ghanaian pregnant women, routinely collected before delivery to rule out bacterial infections causing early onset sepsis, were screened for 12 high-risk (HR), 13 probably/possibly (pHR), and 18 low-risk (LR) HPV types...

Cervical cancer is the fourth most common malignancy in women worldwide. In Chile, cervical cancer is the second leading cause of death among women of reproductive age, causing more than 600 deaths annually. This study was carried out to determine the burden and confirm the predominant human papillomavirus (HPV) genotypes among women presenting for cervical cancer screening in public health services in Chile. Women aged 18-64 years residing in the north and central areas covered by six primary care centers of Santiago, Chile, were invited to participate from March 2014 to August 2015...

With the cover headline 'T cells on the attack,' the journal Science celebrated individualized cancer immunotherapy by adoptive transfer of T cells as the 'Breakthrough of the Year' 2013 (J. Couzin-Frankel in Science 342:1432-1433, 2013). It is less well recognized and appreciated that individualized T cell immunotherapy of cytomegalovirus (CMV) infection is approaching clinical application for preventing CMV organ manifestations, interstitial CMV pneumonia in particular. This coincident medical development is particularly interesting as reactivated CMV infection is a major viral complication in the state of transient immunodeficiency after the therapy of hematopoietic malignancies by hematopoietic cell transplantation (HCT)...

Bodo Plachter
Congenital human cytomegalovirus (HCMV) infection is one leading cause of childhood disabilities. Prevention of congenital HCMV disease by vaccination has consequently been identified as a priority public healthcare goal. Several vaccine candidates have been introduced in the past that aimed at the prevention of primary HCMV infection in pregnancy. None of these has provided complete protection, and no licensed vaccine is thus far available. An additional level of complexity has been reached by recent studies indicating that the burden of HCMV transmission and disease following non-primary infections in pregnancy may be higher than previously anticipated...

Mycobacterium tuberculosis (Mtb), the etiologic agent of tuberculosis (TB), is recognized by a number of pathogen recognition receptors (PRRs), either soluble or predominantly expressed on the surface of various cells of innate and adaptive immunity. C-type lectin receptors (CTLRs) are a class of PRRs which can recognize a variety of endogenous and exogenous ligands, thereby playing a crucial role in immunity, as well as in maintaining homeostasis. Mtb surface ligands, including mannose-capped lipoarabinomannan and cord factor, are important immune modulators which recently have been found to be directly recognized by several CTLRs...

There are concerns about central nervous system (CNS)-replication of HIV-1 in patients on boosted protease inhibitors. Purpose of this study was to compare HIV-1 viral loads (VLs) from patients treated with only boosted dual protease inhibitor (bdPI), versus combination antiretroviral therapy (cART group), containing two nucleoside analogue reverse transcriptase inhibitors (NRTI) and a third partner. All patients from a large German HIV-treatment cohort with available medication, clinical and demographic data, including results from simultaneous HIV-1 viral load (VL) assessments in cerebrospinal fluid (CSF) and blood plasma, were retrospectively evaluated as controlled cross-sectional study...

The frequency of P. penneri isolation from hospital patients, mostly from urine and wounds, keeps on growing, and numerous isolates are multi-drug resistant. P. penneri rods produce lipopolysaccharide (LPS), which may lead to the septic shock. Until now, O-specific polysaccharide has been the best structurally and serologically characterized region of P. penneri LPS. It is worth having an insight into the serological specificity of both poly- and oligosaccharide parts of P. penneri LPS. The P. penneri core region is less structurally diverse than OPS, but still, among other enterobacterial LPS core regions, it is characterized by structural variability...

The pathogenesis of Staphylococcus aureus from local infection to systemic dissemination involves a range of virulence factors including structural and secreted products. Among various control mechanisms, small noncoding RNAs are involved in the regulation of multiple pathogenicity factors in S. aureus. The sRNA SprX which is encoded in the pathogenicity island of methicillin-susceptible S. aureus strain Newman and was shown to influence antibiotic resistance previously, upregulated the expression of virulence genes, especially the cell wall-associated clumping factor B (ClfB) and delta hemolysin (Hld)...

The concept of zoonotic hepatitis E in industrialized countries has emerged with the discovery of swine strains of hepatitis E virus (HEV) genotype 3, closely related to human HEV. Different routes of zoonotic HEV transmission have been recognized, including contact with infected pigs. Workers occupationally exposed to swine (WOES) have been considered a risk group for HEV infection, but contradictory results have been reported. In the present study, we searched for anti-HEV IgG in WOES (butchers, slaughterhouse workers, veterinarians and pig farmers; n = 114) and in the general population (n = 804) in order to investigate the potential occupational risk of zoonotic HEV infection in this work group...

Infection with the parasite Toxoplasma gondii causes serious public health problems and is of great economic importance worldwide. No vaccine is currently available, so the design of efficient vaccine strategies is still a topical question. In this study, we evaluated the immunoprophylactic potential of a T. gondii virulence factor, the rhoptry kinase ROP18, in a mouse model of chronic toxoplasmosis: first using a recombinant protein produced in Schneider insect cells adjuvanted with poly I:C emulsified in Montanide SV71 by a parenteral route or adjuvanted with cholera toxin by the nasal route and second using a DNA plasmid encoding ROP18 adjuvanted with GM-CSF ± IL-12 DNA...

Nowadays, use of prebiotics as feed and food additives has received increasing interest because of the beneficial effects of prebiotics on the health of animals and humans. One of the beneficial effects of prebiotics is stimulation of immune system, which can be direct or indirect through increasing population of beneficial microbes or probiotics, especially lactic acid bacteria and bifidobacteria, in the gut. An important mechanism of action of probiotics and prebiotics, by which they can affect the immune system, is changing the expression of cytokines...
