  Evaluation Summary:

  Low voltage-activated T-type calcium channels (CaV3.1-3.3) are important for several physiological processes. It is challenging to distinguish their specific physiological / pathophysiological roles as they share similar biophysical properties, expression profiles and there is a lack of subtype selective pharmacology. This study reports a spider toxin, Pn3a, which exhibits 100-fold selectivity for inhibiting CaV3.3 over CaV3.1 and CaV3.2 isoforms, and which therefore makes for an excellent reagent for the physiological study of CaV3.3.

  Evaluation Summary:

  This work reveals the pathway by which an important human parasite synthesizes a nuclear hormone receptor ligand critical for progression through its life cycle and demonstrates the potential therapeutic implications of perturbing this pathway. The experiments are insightfully and expertly conceived, designed and executed, and the data support the conclusions. This manuscript will be of general interest to parasitologists, nematode biologists, and those studying transcriptional regulatory networks governed by ligand-gated nuclear receptors.

  Evaluation Summary:

  This paper is of interest to a broad audience of cell biologists, pharmacologists and researchers who work in metabolic diseases. The work provides substantial new insights into the mechanism of action for a plant derived pentacyclic triterpene called celastrol elastrol, in effectively reducing the high fat diet induced tissue hypertrophy in mouse liver and adipose. A series of compelling experiments depict the site of covalent inhibition of the ER stress sensor GRP78 as essential for the beneficial effects in-vivo, supporting the main conclusions.

  Evaluation Summary:

  The manuscript by Munoz et al describes the effect of the bisphosphonate zoledronic acid on tissue-resident macrophages. For this, the investigators used both a fluorescent bisphosphonate derivative and an unmodified zoledronic acid, in combination with macrophage populations isolated from different tissues. Based on the pattern of cytokines released by macrophages in the presence of zoledronic acid, the authors conclude that administration of bisphosphonates could, in addition to preventing bone loss, boost immune responses and lessen the consequences of respiratory infections.
