The high frequency of monoclonal gammopathy in adult patients with C3 glomerulopathy (C3G) emphasizes the role of the monoclonal immunoglobulin (MIg) in the occurrence of renal disease and raises the issue of the therapeutic management. The aim of the study was to evaluate the effect of chemotherapy in a large cohort of patients with MIg-associated C3G. Fifty adult patients with MIg and biopsy-proven C3G were extracted from the French national database of C3G. We retrospectively compared renal outcomes in patients who received or not chemotherapy targeting the underlying B-cell clone...

Dengue virus (DENV) infection causes dengue fever, dengue hemorrhagic fever, or dengue shock syndrome. Interferons (IFNs), and IFN-γ dependent chemokines, chemokine (C-X-C motif) ligand (CXCL)10/IFN-γ-induced protein 10 (IP-10), CXCL9/MIG and CXCL11/I-TAC, and their common receptor chemokine (C-X-C motif) receptor (CXCR)3 are induced by DENV infection; however it has been shown that the latter two could not compensate for the absence of IP-10. This paper reviews studies about DENV and IP-10. Evidences show the importance of IP-10 induction during DENV infection, in macrophages, lymphocytes, hepatic cells, denritic cells, in skin and in the brain...

BACKGROUND: Microinvasive glaucoma surgery (MIGS) is a relatively new addition to the glaucoma treatment paradigm. Small metallic stents are inserted into the trabecular meshwork in order to increase aqueous humour drainage. MIGS procedures are rapidly being adopted due to a more favourable side effect profile when compared to traditional surgery. Remarkably, this rapid rate of utilization has occurred without any published studies on the effect of metal alloys used in these stents on human trabecular meshwork cells (HTMCs)...

Precise positioning of cells is crucial for metazoan development. Despite immense progress in the elucidation of the attractive cues of cell migration, the repulsive mechanisms that prevent the formation of secondary leading edges remain less investigated. Here, we demonstrate that Caenorhabditis elegans Hippo kinases promote cell migration along the anterior-posterior body axis via the inhibition of dorsal-ventral (DV) migration. Ectopic DV polarization was also demonstrated in gain-of-function mutant animals for C...

BACKGROUND: During acute HIV infection (AHI) HIV actively replicates but seroconversion has not yet occurred. Primary HIV infection (PHI) is characterized by a transient non-specific febrile illness, a massive inflammatory response and the progressive appearance of anti-HIV specific antibodies. In this study we have identified patterns of inflammatory biomarkers associated with the innate immunological reaction prior to completion of a full humoral response. METHODS: A symptom-based screening was used to identify AHI in the Manhiça District Hospital in Mozambique...

A perfect ohmic contact formation technique for low-resistance source/drain (S/D) contact of germanium (Ge) n-channel metal-oxide-semiconductor field-effect transistors (MOSFETs) is developed. A metal-interlayer-semiconductor (M-I-S) structure with an ultrathin TiO2/GeO2 interlayer stack is introduced into the contact scheme to alleviate Fermi-level pinning (FLP), and reduce the electron Schottky barrier height (SBH). The TiO2 interlayer can alleviate FLP by preventing formation of metal-induced gap states (MIGS) with its very low tunneling resistance and series resistance and can provide very small electron energy barrier at the metal/TiO2 interface...

We demonstrate the contact resistance reduction for III-V semiconductor-based electrical and optical devices using the interfacial dipole effect of ultrathin double interlayers in a metal-interlayers-semiconductor (M-I-S) structure. An M-I-S structure blocks metal-induced gap states (MIGS) to a sufficient degree to alleviate Fermi level pinning caused by MIGS, resulting in contact resistance reduction. In addition, the ZnO/TiO2 interlayers of an M-I-S structure induce an interfacial dipole effect that produces Schottky barrier height (ΦB) reduction, which reduces the specific contact resistivity (ρc) of the metal/n-type III-V semiconductor contact...

Recently many new devices and procedures have been developed to lower intraocular pressure in a less invasive and purportedly safer manner than traditional glaucoma surgery. These new devices might encourage an earlier transition to surgery and reduce the long term commitment to topical glaucoma medications with their associated compliance and intolerance issues. While often seen as an adjunct to cataract surgery, a growing body of evidence suggests that primary MIGS may be a viable initial treatment option...

The Mesenchymal Stromal Cells from umbilical cord Wharton's jelly (WJSCs) are a source of cells with high potentiality for the treatment of human immunological disorders. Footprints of the oncogenic viruses Simian Virus 40 (SV40) and JC Virus (JCPyV) have been recently detected in human WJSCs specimens. The aim of this study is to evaluate if WJSCs can be efficiently infected by these Polyomaviruses and if they can potentially exert tumoral activity. Cell culture experiments indicated that WJSCs could sustain both SV40 and JCPyV infections...

Endometrial cancer is a frequently occurring gynecological disorder. Estrogen-dependent endometrioid carcinoma is the most common type of gynecological cancer. One of the major pathologic phenomena of endometrial cancer is the loss of estrogen (E2) and progesterone (P4) control over uterine epithelial cell proliferation. P4 antagonizes the growth-promoting properties of E2 in the uterus. P4 prevents the development of endometrial cancer associated with unopposed E2 by blocking E2 actions. Mitogen inducible gene 6 (Mig-6, Errfi1, RALT, or gene 33) is an immediate early response gene that can be induced by various mitogens and common chronic stress stimuli...

Individual susceptibility to HIV is heterogeneous, but the biological mechanisms explaining differences are incompletely understood. We hypothesized that penile inflammation may increase HIV susceptibility in men by recruiting permissive CD4 T cells, and that male circumcision may decrease HIV susceptibility in part by reducing genital inflammation. We used multi-array technology to measure levels of seven cytokines in coronal sulcus (penile) swabs collected longitudinally from initially uncircumcised men enrolled in a randomized trial of circumcision in Rakai, Uganda...

BACKGROUND: Glaucoma comprises a group of neurodegenerative diseases resulting in retinal ganglion cell death within the optic nerve head. It is projected to affect almost 80 million people worldwide by 2020. The condition's asymptomatic nature translates to over half of glaucoma sufferers being unaware of their condition. By the time of diagnosis, irreversible blindness is likely to have occurred. Prime areas of glaucoma research therefore include identification and optimization of risk factors for the disease, accurate and early diagnostic tools and novel therapeutic methods...

Porphyromonas gingivalis, a keystone pathogen in chronic periodontitis, has been found to associate with remote body organ inflammatory pathologies, including atherosclerosis and Alzheimer's disease (AD). Although P. gingivalis has a plethora of virulence factors, much of its pathogenicity is surprisingly related to the overall immunosuppression of the host. This review focuses on P. gingivalis aiding suppression of the host's adaptive immune system involving manipulation of cellular immunological responses, specifically T cells and B cells in periodontitis and related conditions...

The tests for diagnosing latent tuberculosis infection (LTBI) are limited by poor predictive value for identifying people at highest risk for progression to active TB, and have varying sensitivity and specificity in different populations. The identification of a more robust signature for LTBI is important for TB prevention and elimination. A pilot study was conducted with samples from immigrants to the U.S. that were screened for LTBI by the three commercially approved tests: Tuberculin Skin Test (TST), QuantiFERON-TB Gold In-Tube (QFT-GIT), and T-SPOT...

Inflammation of the skin is the pathological base of contact dermatitis (CD), and cytokines are very important in its pathogenesis. Recently it has been shown that interferon (IFN)-γ, and the IFN-γ dependent chemokines, monokine induced by IFN-γ (MIG), IFN-γ-induced protein 10 (IP-10), and IFN-inducible T cell alpha chemoattractant (I-TAC), play an important role in CD. Allergic CD (ACD) is a T-cell-mediated disease in which expression of a distinct repertoire of chemokines results in the recruitment of effector T cells into the skin...
