A Case for Anti‐IgE Vaccination

open access: yesAllergy, EarlyView.
ABSTRACT Immunoglobulin E (IgE) plays a central role in allergic diseases by binding to the high‐affinity receptor FcεRI on mast cells and basophils, where allergen‐induced crosslinking triggers potent inflammatory responses. Various mechanisms by which IgE responses are generated and functionally regulated remain elusive despite many years of research.

Peri‐operative management of diabetes mellitus: a multidisciplinary consensus statement from the Association of Anaesthetists and the Joint British Diabetes Societies for Inpatient Care group

open access: yesAnaesthesia, EarlyView.
Summary Introduction Surgery in patients with diabetes mellitus is associated with increased morbidity and mortality compared with those who do not have diabetes mellitus. This is likely multifactorial and could be attributed to organisational issues; dysglycaemia; hospital‐acquired diabetic ketoacidosis; errors with insulin prescribing and ...

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Plant organelle C‐to‐U RNA editing factors can operate successfully in yeast (Saccharomyces cerevisiae) as an easily amenable eukaryotic system for their functional analysis

open access: yesThe FEBS Journal, EarlyView.
Plant‐type pentatricopeptide repeat proteins capable of C‐to‐U RNA editing perform faithfully when expressed in a new heterologous system, the yeast Saccharomyces cerevisiae. They were tested with constitutive and inducible expression and with a set of different solubility tags. PPR56, PPR65, and PPR78 from P.

The effect of various carbon sources on the growth of single-celled cyanophyta [PDF]

open access: yes
In 19 strains of unicellular blue-green algae, belonging to general Synechococcus, Synechocystis, Aphanocapsa and Aphanothece, the capacity of growth under mixotrophic conditions in mineral media with organic carbon sources (carbohydrates, polyols) was ...

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

open access: yesThe FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Redox environment modulates aggregation of ataxin‐3 in vitro — Implications for drug screening of cysteine‐rich proteins

open access: yesThe FEBS Journal, EarlyView.
Redox environment modulates in vitro aggregation of Ataxin‐3, the protein implicated in spinocerebellar ataxia type 3. Reducing conditions stabilize native monomers and prevent aggregation, whereas oxidative conditions promote the formation of non‐native conformers and disulfide‐linked oligomers within the Josephin domain (JD).

Harnessing S. cerevisiae to advance the engineering of pentatricopeptide repeat proteins

open access: yesThe FEBS Journal, EarlyView.
Heterologous expression systems have been instrumental in furthering our understanding of plant RNA editing proteins. In this commentary, we discuss how the establishment of yeast as a model for studying plant RNA editing by Ramanathan et al. could advance the engineering of pentatricopeptide repeat proteins, and how in return pentatricopeptide repeat ...

H2‐dependent modulation of tetrahydromethanopterin S‐methyltransferase (Mtr complex) activity by the small protein MtrR in Methanosarcina mazei

open access: yesThe FEBS Journal, EarlyView.
Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...

Human IDO2 exhibits unique binding affinities distinct to those of human IDO1

open access: yesThe FEBS Journal, EarlyView.
Although indoleamine 2,3‐dioxygenase 2 (IDO2) is highly homologous to IDO1, it displays markedly lower catalytic activity. We found that IDO2 binds L‐tryptophan (L‐Trp) in a flipped orientation stabilized by the IDO2‐specific residue His143. Replacement of His143 with the IDO1‐equivalent tyrosine restored an IDO1‐like binding mode and increased ...
