Genomic variability of lipooligosaccharide biosynthesis locus and sequence type among Campylobacter jejuni isolated from patients with Guillain-Barré syndrome

open access: yesMicrobiology Spectrum
Lipooligosaccharide (LOS) is a crucial component of the Campylobacter jejuni (C. jejuni) cell membrane that mimics human gangliosides and can induce autoimmune neuropathies like Guillain-Barré syndrome (GBS). Approximately one in 1,000 C.

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

THE AXIS DEER (AXIS AXIS ) IN BRIJUNI NATIONAL PARK

open access: yesJournal of Central European Agriculture, 2008
The axis deer (Axis axis) was imported from Germany and introduced into Brijuni in 1911. Brijuni are a group of islands in the Adriatic Sea along the western coast of the southern peak of the Istrian Peninsula in the Republic of Croatia. In 1983 the area was declared a National Park.

Axis Screw Fixation – A Step-by-Step Review of the Surgical Techniques

open access: yesBrazilian Neurosurgery, 2017
In this article, we present the techniques of axis screw fixation (laminar, pars, pedicle and transarticular screws), discussing the indications and contraindications of each one, as well as surgical tips and anatomical landmarks.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

PD-1/PD-L1 Axis Downregulation in Guillain-Barré Syndrome: A Potential Mechanism Driving the Autoimmune Pathogenesis

open access: yesInternational Journal of Infectious Diseases
Introduction: Guillain-Barré syndrome (GBS), an immune-mediated disorder of the peripheral nervous system characterized by progressive muscle weakness, is often triggered by Campylobacter jejuni infection. Molecular mimicry between C.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Resistome phylodynamics of multidrug-resistant Shigella isolated from diarrheal patients

open access: yesMicrobiology Spectrum
Multi-drug resistance (MDR) in Shigella continues to pose a significant public health challenge, particularly in developing countries. Recent advances in genomics strengthen the surveillance of MDR-pathogens and antimicrobial resistance (AMR) mediators ...

Wnt, Ptk7, and FGFRL expression gradients control trunk positional identity in planarian regeneration

open access: yeseLife, 2016
Mechanisms enabling positional identity re-establishment are likely critical for tissue regeneration. Planarians use Wnt/beta-catenin signaling to polarize the termini of their anteroposterior axis, but little is known about how regeneration signaling ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...
