Anaphylaxis is a severe allergic reaction with a rapid onset and it is potentially life-threatening. Its clinical manifestations are varied; they may affect the skin, the cardiovascular system, the respiratory system, and the digestive system, among others. The treatment of choice, which is an intra-muscular injection of epinephrine (adrenaline), must be applied promptly.

Correction to: Combination of ELISA screening and seroneutralisation tests to expedite Zika virus seroprevalence studies.

In the original publication of this article [1], Table 1 has some errors.

Combination of ELISA screening and seroneutralisation tests to expedite Zika virus seroprevalence studies.

Here we propose a strategy allowing implementing efficient and practicable large-scale seroepidemiological studies for Zika Virus (ZIKV). It combines screening by a commercial NS1 protein-based Zika IgG ELISA, and confirmation by a cytopathic effect-based virus neutralization test (CPE-based VNT). In post-epidemic samples from Martinique Island blood donors (a population with a dengue seroprevalence above 90%), this strategy allowed reaching specificity and sensitivity values over 98%.

Calcium sensing receptor effects in adipocytes and liver cells: Implications for an adipose-hepatic crosstalk.

The calcium sensing receptor (CaSR) is expressed in human adipose cells, and its activation may associate with adipose tissue (AT) dysfunction. We evaluated whether CaSR stimulation influences adipocyte triglyceride (TG) and fatty acid binding protein 4 (aP2) content, and hepatocyte TGs and proinflammatory cytokine expression. The effect of the calcimimetic cinacalcet on TGs (fluorimetry), lipogenic genes (qPCR) and aP2 (immunoblot) was evaluated in LS14 adipocytes or AT.

Preadipocyte proliferation is elevated by calcium sensing receptor activation.

Obesity is a major worldwide problem, despite considerable efforts against it. While excess body fat defines obesity, adipose tissue quality and functionality are key to whether cardiovascular and metabolic comorbidities develop. Adipose tissue cellular composition can vary considerably, and excess adipocyte progenitors (preadipocytes) is associated with obesity.

Antiphospholipase A2 Receptor Antibody Levels Predict the Risk of Posttransplantation Recurrence of Membranous Nephropathy.

Background: Secretory phospholipase A2 receptor (PLA2R) is the target antigen of the auto-antibodies produced in most (∼ 70%) patients with primary membranous nephropathy (pMN). The applicability of anti-PLA2R1 antibody monitoring for the prediction of MN recurrence in kidney transplant recipients still is a matter of debate.

Methods: We sought to characterize the presence and concentration of anti-PLA2R antibodies by enzyme-linked immunosorbent assay (ELISA) in a cohort of 21 patients with pMN before and after transplantation to evaluate whether anti-PLA2R concentrations could predict pMN recurrence.

Calcium, obesity, and the role of the calcium-sensing receptor.

The elevated prevalence of obesity worldwide is a challenging public health problem. Dietary calcium intake is frequently below recommendations, and evidence gathered for more than a decade suggests that inadequate calcium intake may be related to increased body weight and/or body fat, although a consensus has yet to be reached. Whole-body energy balance and the cellular mechanisms involved have been proposed to explain this relationship, and increasing evidence from epidemiological, clinical, and basic research lends support to the hypothesis that calcium is linked to the regulation of body weight.

Identification of novel 11β-HSD1 inhibitors by combined ligand- and structure-based virtual screening.

11 beta-hydroxysteroid dehydrogenase type 1 (11β-HSD1) converts cortisone to cortisol in a NADPH dependent manner. Overexpression of 11β-HSD1 in key metabolic tissues is related to the development of type 2 diabetes, obesity, hypertension and metabolic syndrome. Using crystal structures of human 11β-HSD1 in complex with inhibitors as source of structural information, a combined ligand and structure-based virtual screening approach was implemented to identify novel 11β-HSD1 inhibitors.
