Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Prompt-guided LLM agent for end-to-end ontology learning

open access: yesÌнформаційні технології та компʼютерна інженерія
Turning the vast knowledge of large language models (LLMs) into logical, machine-interpretable ontologies poses a difficult task. Conventional single-prompt strategies often generated ambiguous or mutually inconsistent triples could not be merged safely ...

A set-based reasoner for the description logic $\shdlssx$ (Extended Version)

open access: yes, 2018
We present a \ke-based implementation of a reasoner for a decidable fragment of (stratified) set theory expressing the description logic $\dlssx$ ($\shdlssx$, for short). Our application solves the main TBox and ABox reasoning problems for $\shdlssx$. In

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

A \textsf{C++} reasoner for the description logic $\shdlssx$ (Extended Version)

open access: yes, 2018
We present an ongoing implementation of a \ke\space based reasoner for a decidable fragment of stratified elementary set theory expressing the description logic $\dlssx$ (shortly $\shdlssx$).

Investigating the cell of origin and novel molecular targets in Merkel cell carcinoma: a historic misnomer

open access: yesMolecular Oncology, EarlyView.
This study indicates that Merkel cell carcinoma (MCC) does not originate from Merkel cells, and identifies gene, protein & cellular expression of immune‐linked and neuroendocrine markers in primary and metastatic Merkel cell carcinoma (MCC) tumor samples, linked to Merkel cell polyomavirus (MCPyV) status, with enrichment of B‐cell and other immune cell

Methodology for testing and validating knowledge bases [PDF]

open access: yes
A test and validation toolset developed for artificial intelligence programs is described. The basic premises of this method are: (1) knowledge bases have a strongly declarative character and represent mostly structural information about different ...
