INTRODUCTION: At the present time, the study of mechanisms of recognition of foreign agents, which is realized by means of Toll-like receptors (TLR) of the innate immune system, has become one of the main tasks of clinical immunology. The aim of our study was to investigate the prevalence of polymorphism of Toll-like receptor 4 (Asp299Gly, Gly299Gly) among children with chronic pyelonephritis (CP) and determine the association of this TLR4 polymorphism with phenotypic features of chronic pyelonephritis and level of interleukin-6 (IL-6)...

The current study describes a new support system for fine focusing and near-perfect astigmatism correction for scanning electron microscopy (SEM). The signal-to-noise ratio of a series of SEM images obtained from fast scan rates (TV scan) was adopted as a new metric for evaluating focus. Measured signal-to-noise ratio values were converted to an acoustic signal (sound wave frequency) using digital image processing techniques, enabling the SEM user to evaluate image focus using the auditory modality. Accurate focusing and correcting astigmatism in general-purpose SEM is traditionally time-consuming and difficult...

HIV/CMV co-infected persons despite prolonged viral suppression often experience persistent immune activation, have an increased frequency of myeloid derived suppressor cells (MDSC) and are at increased risk for cardiovascular disease. We examined how HIV MDSC control CD4(+) T cell IFNγ response to a CMVpp65 peptide pool (CMVpp65). We show that HIV/CMV co-infected persons with virologic suppression and recovered CD4(+) T cells compared to HIV(-)/CMV(+) controls exhibit an increase in CD4(+)CX3CR1(+)IFNγ(+) cells in response to CMVpp65; MDSC depletion further augmented CD4(+)CX3CR1(+)IFNγ(+) cells and IFNγ production...

BACKGROUND Human leukocyte antigen (HLA) mismatch is a characteristic feature of post-orthotopic liver transplantation (OLT) hepatitis C. To investigate the importance of donor HLA-restricted immune cells in post-OLT hepatitis C recurrence, we analyzed the frequency of donor chimerism and the clinical course of post-OLT hepatitis C. MATERIAL AND METHODS We analyzed peripheral blood chimerism in 11 HCV-reinfected patients with post-HLA mismatched OLT. Patients were divided into 2 groups: the OLT chronic hepatitis C (CHC) group (n=8), exhibiting active hepatitis C recurrence; and the OLT-persistently normal ALT (PNALT) group (n=3), without active hepatitis...

A useful method for eliminating the detrimental effect of laser frequency instability on Brillouin signals by employing the self-heterodyne detection of Rayleigh and Brillouin scattering is presented. From the analysis of Brillouin scattering spectra from fibers with different lengths measured by heterodyne detection, the maximum usable pulse width immune to laser frequency instability is obtained to be about 4 µs in a self-heterodyne detection Brillouin optical time domain reflectometer (BOTDR) system using a broad-band laser with low frequency stability...

Large numbers of statistically significant associations between sentinel SNPs and case-control status have been replicated by genome-wide association studies. Nevertheless, few underlying molecular mechanisms of complex disease are currently known. We investigated whether variation in binding of a transcription factor, the vitamin D receptor (VDR) whose activating ligand vitamin D has been proposed as a modifiable factor in multiple disorders, could explain any of these associations. VDR modifies gene expression by binding DNA as a heterodimer with the Retinoid X receptor (RXR)...

Trypanosoma brucei causes human African trypanosomiasis and regularly switches its major surface antigen, VSG, thereby evading the host's immune response. VSGs are monoallelically expressed from subtelomeric expression sites (ESs), and VSG switching exploits subtelomere plasticity. However, subtelomere integrity is essential for T. brucei viability. The telomeric transcript, TERRA, was detected in T. brucei previously. We now show that the active ES-adjacent telomere is transcribed. We find that TbRAP1, a telomere protein essential for VSG silencing, suppresses VSG gene conversion-mediated switching...

Worldwide mobile telephone and microwave use have resulted in an increasing presence of extremely low-frequency electromagnetic field radiations (ELF-EMFs) in ecosystems. ELF-EMFs have been associated with altered physiological processes that can adversely affect exposed organisms. In this study, Trichoplusia ni Hübner larvae were exposed for 24, 48, or 72 h to ELF-EMFs (60 Hz and 2.0 mT) to assess effects on immune response parameters and fertility. Trichoplusia ni life cycle and fertility were not affected by 24-h exposure...

In immediate serial recall, it is well established that performance is influenced by lexical factors such as imageability and word frequency. However, when participants are asked to recall the to-be-remembered items in their reverse order, known as backward recall, lexical factors produced contradictory findings. In 4 experiments, we tested the role of response modality in modulating the effects of imageability and word frequency in backward recall. The magnitude of the 2 tested lexical factors was only slightly reduced in backward compared with forward recall when participants responded manually...

The incidence of Staphylococcus aureus bacteremia (SAB) is significantly higher in African American (AA) than in European-descended populations. We used admixture mapping (AM) to test the hypothesis that genomic variations with different frequencies in European and African ancestral genomes influence susceptibility to SAB in AAs. A total of 565 adult AAs (390 cases with SAB; 175 age-matched controls) were genotyped for AM analysis. A case-only admixture score and a mixed χ(2)(1df) score (MIX) to jointly evaluate both single-nucleotide polymorphism (SNP) and admixture association (P<5...

BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most common cancers in China and frequently occurs with chronic hepatitis B virus infection. To investigate whether cell-based cancer immunotherapy induces tumor specific immune responses in patients with HCC and provides clinical benefits, as well as to elucidate the most immunogenic tumor associated antigens (TAAs), multiple antigen stimulating cellular therapy (MASCT) was applied in addition to standard of care. METHODS: Mature dendritic cells (DCs) and activated T cells prepared for MASCT were generated from autologous peripheral blood mononuclear cells (PBMCs)...

Background.: Human infection by orthopoxviruses is being reported with increasing frequency, attributed in part to the cessation of smallpox vaccination and concomitant waning of population-level immunity. In July 2015, a female resident of interior Alaska, presented to an urgent care clinic with a dermal lesion consistent with poxvirus infection. Laboratory testing of a virus isolated from the lesion confirmed infection by an Orthopoxvirus. Methods.: The virus isolate was characterized by using electron microscopy and nucleic acid sequencing...

The newborn's immune system must transition from a sterile haploidentical uterus to the world full of antigens. Regulatory B-cells (Breg; broadly defined as CD19(+)CD24(hi)CD38(hi)) are tolerance promoters in the adult immune system. They can inhibit IFN-γ and IL-17 production by T-cells and are essential in different conditions, including pregnancy. Breg have still not been well characterized in umbilical cord blood, where we hypothesize that they are pivotal in the achievement of tolerance. We studied CD19(+)CD24(hi)CD38(hi) Breg in healthy umbilical cord blood (hUCB) compared to healthy peripheral adult blood (hAPB)...

Coexistence of the hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) is an uncommon phenomenon, and the underlying mechanisms remain largely unknown. Amino-acid (aa) substitution from glycine to arginine at aa 145 (G145R), in the major hydrophilic region, has been reported in patients with HBsAg and anti-HBs coexistence. However, there is limited knowledge about the clinical features and viral quasispecies characteristics associated with G145R mutant hepatitis B virus (HBV) infection...

The purpose of this study was to evaluate if an early exposure to human papillomavirus (HPV) during the prenatal period or infancy could result in HPV16-specific T helper (Th) responses resembling those of adults with HPV-induced lesions. We tested HPV16-specific cell-mediated immunity (CMI) in children born with HPV-positive umbilical cord blood and/or placenta or having persistent oral HPV infection and in constantly oral HPV-negative controls. Peripheral blood mononuclear cells from 33 children from the Finnish HPV Family Study cohort (mean age 14...

The synthetic androgen, 17 alpha-methyltestosterone (MT), is profusely used and practically needed in the production of all-male Nile tilapia fry; however, such androgenic hormones badly disrupt the immune system. This study aimed to alleviate or counteract the immunotoxic effect of MT using vitamin C (ascorbic acid, vit C). Our results show that the highest phagocytic activity (PA), phagocytic index (PI) and lysozyme activity were detected in the vit C group and the MT plus vit C group. Furthermore, PA and PI were significantly suppressed, but lysozyme activity was stronger in the MT group than the control...

Parvalbumin inhibitory interneurons (PVIs) are crucial for maintaining proper excitatory/inhibitory balance and high-frequency neuronal synchronization. Their activity supports critical developmental trajectories, sensory and cognitive processing, and social behavior. Despite heterogeneity in the etiology across schizophrenia and autism spectrum disorder, PVI circuits are altered in these psychiatric disorders. Identifying mechanism(s) underlying PVI deficits is essential to establish treatments targeting in particular cognition...

Experimental autoimmune encephalomyelitis (EAE) is a demyelinating pathology of the central nervous system (CNS) used as a model to study multiple sclerosis immunopathology. EAE has also been extensively employed to evaluate potentially therapeutic schemes. Considering the presence of an immune response directed to heat shock proteins (hsps) in autoimmune diseases and the immunoregulatory potential of these molecules, we evaluated the effect of a previous immunization with a genetic vaccine containing the mycobacterial hsp65 gene on EAE development...

Development of immunoprotection against visceral leishmaniasis (VL) focused on the identification of antigens capable of inducing a Th1 immune response. Alternatively, antigens targeting the CD8 and T-regulatory responses are also relevant in VL pathogenesis and worthy of being included in a preventive human vaccine. We assessed in active and cured patients and VL asymptomatic subjects the clinical signs and cytokine responses to the Leishmania donovani nucleoside hydrolase NH36 antigen and its N-(F1), central (F2) and C-terminal (F3) domains...
