Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Regulation of β-cell death by ADP-ribosylhydrolase ARH3 via lipid signaling in insulitis [PDF]

Background: Lipids are regulators of insulitis and β-cell death in type 1 diabetes development, but the underlying mechanisms are poorly understood. Here, we investigated how the islet lipid composition and downstream signaling regulate β-cell death ...

Indian hedgehog (Ihh) both promotes and restricts thymocyte differentiation [PDF]

, 2009
We show that Indian Hedgehog (Ihh) regulates T-cell development and homeostasis in both fetal and adult thymus, controlling thymocyte number. Fetal Ihh-/- thymi had reduced differentiation to double-positive (DP) cell and reduced cell numbers compared ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Role of phosphoinositide 3-kinases in mast cell activation [PDF]

, 2009
Mast cells are primary effector cells in allergy and chronic inflammation. Class IB (PI3Kγ) and class IA (PI3Kδ) PI3K have been shown to play major roles in mast cell activation: antigen/IgE stimulation triggers autocrine/paracrine activation of mast ...

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Dissecting the roles of WNT signaling in breast cancer using "in vitro" and "in vivo" experimental models [PDF]

, 2009
Canonical WNT pathway regulates expression of target genes by modulating intracellular amount of β-catenin. Without WNT pathway activation, a so-called “destruction complex” including APC and Axin facilitates the degradation of β-catenin. Upon binding of

AUNIP/C1orf135 directs DNA double-strand breaks towards the homologous recombination repair pathway

Nature Communications, 2017
DNA double strand breaks can be repaired by homology-independent or homology-directed mechanisms. The choice between these pathways is a key event for genomic stability maintenance.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
