Preeclampsia and Glomerulonephritis: A Bidirectional Association
No full textPurpose of Review: We focus on the current understanding of preeclampsia (PE) in order to examine how it mediates glomerular injury and affects the course of glomerulonephritis (GNs). In addition, this review discusses the role of GNs on the development of PE. Recent Findings: In PE, the dysfunctional utero-placental perfusion causes the release into the mother’s circulation of anti-angiogenic substances, leading to systemic endotheliosis. In preeclamptic patients, the imbalance between pro- and anti-angiogenic factors is responsible for the kidney injury, and PE may reveal a silent pre-existent GN or may induce the development of the disease. Moreover, in women with chronic kidney disease (CKD), it could accelerate the disease progression. In any case, GNs compromise renal function, making the kidney less responsive to physiological changes that occur during pregnancy and, at the same time, cause maternal vascular inflammation, representing a risk factor for PE development. Summary: Although a bidirectional correlation between GNs and PE has been demonstrated, the data are limited, and further large studies are warranted. Close collaboration between a multidisciplinary team of obstetricians and nephrologists is essential to establish the correct diagnosis and safely manage these vulnerable women and their fetuses
The mucosal immune system and IgA nephropathy
No full textThe precise pathogenesis of immunoglobulin A nephropathy (IgAN) is still not clearly established but emerging evidence confirms a pivotal role for mucosal immunity. This review focuses on the key role of mucosa-associated lymphoid tissue (MALT) in promoting the onset of the disease, underlying the relationship among microbiota, genetic factors, food antigen, infections, and mucosal immune response. Finally, we evaluate potential therapies targeting microbes and mucosa hyperresponsiveness in IgAN patients
TGF-beta: a master switch in tumor immunity.
No full textThe capacity of the immune system to distinguish foreign from self-antigen, and to subsequently eliminate the threat of disease without injuring the host is crucial to survival. It also serves to defend against tumor formation and progression via a process termed cancer immunosurveillance. Innate and adaptive immune cell types and effector molecules collectively function as extrinsic tumor-suppressor mechanisms. However, tumors may escape immune surveillance through a variety of mechanisms that create a local microenvironment that is unfavorable for effective tumor immunity. Transforming growth factor β (TGF-β) has pleiotropic effects on the immune system, and is recognized as one of the most potent immunosuppressive agents in facilitating oncogenesis. The TGF-β pathway promotes cancer progression by concomitantly enhancing tumor metastases while inhibiting the protective host immunity. In this review, we discuss mechanisms through which TGF-β interferes with the development of an anti-tumor immunity and potential means by which to circumvent its activity in order to define more effective cancer immunotherapies

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
