Interkingdom Interactions in the Gut: Ecological Mechanisms, Homeostasis, and Therapeutic Modulation

Gut Medicine, EarlyView.
ABSTRACT The gut microbiota constitutes a highly complex and dynamic ecosystem that profoundly influences host physiology, metabolism, and immunity. This review provides an integrative overview of the mechanisms through which gut microorganisms—particularly bacteria and fungi—interact with host cells and with each other to maintain intestinal ...

Salmonella adhesion is decreased by hypoxia due to adhesion and motility structure crosstalk

Veterinary Research, 2023
Initial stages of Salmonella Typhimurium infection involve a series of coordinated events aimed at reaching, attaching to, and invading host cells. Virulence factors such as flagella, fimbriae, and secretion systems play crucial roles in these events and

Antigenic relationships among type-1 fimbriae of Enterobacteriaceae revealed by immuno-electronmicroscopy [PDF]

Journal of Medical Microbiology, 1987
Antigenic relationships among type-1 fimbriae of 40 strains of Enterobacteriaceae representing 19 species and seven genera were determined by immuno-electronmicroscopy. Ten distinct antigenic groups were distinguished. Intra- and inter-generic relationships were observed although some antigenic groups were species-specific only. Antigenic relationships

Expression of type 1 fimbriae and mannose-sensitive hemagglutinin by recombinant plasmids [PDF]

Infection and Immunity, 1989
Deletions within the cloned genes (fimA) encoding the type 1 major fimbrial subunits of two isolates of Klebsiella pneumoniae resulted in a nonfimbriate but hemagglutinating phenotype after transformation of Escherichia coli HB101 or ORN103. Phenotypic expression of type 1 fimbriae could be restored by transformation with plasmids containing the fimA ...

Associations of cannabis use, tobacco use and co‐use with brain volume: A systematic review and meta‐analysis

Addiction, EarlyView.
Abstract Background and aims Cannabis is the most widely used illicit drug worldwide and is often co‐used with tobacco, the leading cause of preventable death. Although cannabis and tobacco have distinct neurobiological actions, their associations with brain volumes are unclear.

Characterization of Shigella type 1 fimbriae: expression, FimA sequence, and phase variation [PDF]

Infection and Immunity, 1997
This study documents the presence of type 1 fimbriae on Shigella and confirms these mannose-sensitive adherence structures to be bona fide components of the Shigella surface. While laboratory-passaged Shigella strains and lyophilized clinical isolates failed to express type 1 fimbriae, 6 of 20 recent clinical isolates, including 4 Shigella flexneri ...

Tau‐targeting active immunotherapy slows progression and reduces pathology in mouse models of tauopathy

Brain Pathology, EarlyView.
The efficacy of the novel anti‐tau active immunotherapy, p5555kb, was tested using two mouse models of tau pathology. p5555kb inoculation increased the survival rate and reduced tau pathology in tau‐overexpressing P301L mice and decreased tau seeding in the brains of C57BL/6 mice injected with human‐purified Alzheimer's disease tau.
