Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

c-Jun Proto-Oncoprotein Plays a Protective Role in Lung Epithelial Cells Exposed to Staphylococcal α-Toxin

open access: yesFrontiers in Cellular and Infection Microbiology, 2018
c-Jun is a member of the early mammalian transcriptional regulators belonging to the AP-1 family, which participates in a wide range of cellular processes such as proliferation, apoptosis, tumorigenesis, and differentiation.

Resurfacing receptor binding domain of Colicin N to enhance its cytotoxic effect on human lung cancer cells

open access: yesComputational and Structural Biotechnology Journal, 2021
Colicin N (ColN) is a bacteriocin secreted by Escherichia coli (E. coli) to kill other Gram-negative bacteria by forcefully generating ion channels in the inner membrane.

Host glycan recognition by a pore forming toxin. [PDF]

open access: yesStructure, 2012
An exposed F-type lectin domain fused to the N-terminus of a cholesterol-dependent cytolysin scaffold allows Streptococcus mitis lectinolysin to cluster at fucose-rich sites on target cell membranes, thereby leading to increased pore-forming toxin activity.

Pore-forming activity of clostridial binary toxins

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2016
Clostridial binary toxins (Clostridium perfringens Iota toxin, Clostridium difficile transferase, Clostridium spiroforme toxin, Clostridium botulinum C2 toxin) as Bacillus binary toxins, including Bacillus anthracis toxins consist of two independent proteins, one being the binding component which mediates the internalization into cell of the ...

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Serine clamp of Clostridium perfringens binary toxin BECb (CPILEb)-pore confers cytotoxicity and enterotoxicity

open access: yesCommunications Biology
BEC (CPILE) is a virulence factor of the pathogen, Clostridium perfringens, which has caused foodborne outbreaks in Japan. BEC is a binary toxin that comprises the enzymatic A-component (BECa) and the B-component (BECb); the latter forms a membrane pore ...

Cytotoxic Effect of Recombinant Fragaceatoxin C on Peripheral Blood Mononuclear Cells [PDF]

open access: yesJournal of Advanced Biomedical Sciences, 2020
Background & Objectives: Actinoporins from sea anemones are potent pore-forming toxins. Fragaceatoxin C belongs to this family with a molecular weight of 20 kDa that mainly binds sphingomyelin in membranes and forming 2nm in diameter cation-selective ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Exolysin Shapes the Virulence of Pseudomonas aeruginosa Clonal Outliers

open access: yesToxins, 2017
Bacterial toxins are important weapons of toxicogenic pathogens. Depending on their origin, structure and targets, they show diverse mechanisms of action and effects on eukaryotic cells.
