Chemokines in Alzheimer's Disease: Early Defence, Late Damage and the Impact of Sex and Infection

Basic &Clinical Pharmacology &Toxicology, Volume 139, Issue 2, August 2026.
ABSTRACT Chemokines constitute a versatile signalling network maintaining homeostasis and glia–neuron communication in the healthy brain but become progressively dysregulated during aging and Alzheimer's disease (AD). This review examines how chemokine systems transition from tightly regulated homeostatic signals to drivers of chronic neuroinflammation

A Comparison of Endodontic Microbiomes Associated With Symptomatic and Asymptomatic Apical Periodontitis by Next‐Generation Sequencing

International Endodontic Journal, Volume 59, Issue 8, Page 1608-1618, August 2026.
ABSTRACT Aim This cross‐sectional study aimed to compare the endodontic microbiome assessed from root canals of teeth associated with either symptomatic or asymptomatic apical periodontitis and analysed by 16S rDNA gene sequencing. Methodology 60 teeth presenting clinical and radiographic signs of symptomatic or asymptomatic apical periodontitis (n ...

Bactofilins are essential spatial organizers of peptidoglycan insertion in the Lyme disease spirochete Borrelia burgdorferi

Journal of Bacteriology
The Lyme disease spirochete Borrelia burgdorferi has a distinctive pattern of growth. Newly born cells elongate by primarily inserting peptidoglycan at mid-cell, while in longer cells, additional insertion sites form at the one-quarter and three-quarter ...

Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies

Journal of Applied Entomology, Volume 150, Issue 7, Page 990-1015, August 2026.
ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.

Riboflavin Salvage Supports Glycolysis in Borrelia burgdorferi Through Flavin‐Dependent NAD+ Regeneration

Molecular Microbiology, Volume 126, Issue 2, Page 208-219, August 2026.
The Lyme disease agent Borrelia burgdorferi has limited metabolic capabilities and depends on salvage of riboflavin via the BB0316‐BB0319 transport system for generation of critical flavin cofactors FMN and FAD. Riboflavin is important for NAD+ regeneration to fuel glycolysis.

The Periplasmic Flagellum of Spirochetes

Microbial Physiology, 2004
Although spirochete periplasmic flagella have many features similar to typical bacterial flagella, they are unique in their structure and internal periplasmic location. This location provides advantages for pathogenic spirochetes to enter and to adapt in the appropriate host, and to penetrate through matrices that inhibit the motility of most other ...
