Epithelial cell shedding and barrier function: a matter of life and death at the small intestinal villus tip [PDF]

open access: yes, 2015
The intestinal epithelium is a critical component of the gut barrier. Composed of a single layer of intestinal epithelial cells (IECs) held together by tight junctions, this delicate structure prevents the transfer of harmful microorganisms, antigens ...

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

open access: yesAnimal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

Single channel recordings obtained from basolateral membranes of isolated rabbit enterocytes

open access: yesFEBS Letters, 1985
Epithelial cells isolated by hyaluronidase incubation from rabbit small intestine were used to explore the presence of ionic channels by the patch‐clamp method. Recordings were made from cell‐attached or excised patches of basolateral membrane. Evidence was obtained for the presence of at least two kinds of channels conducting potassium currents.

Pharmacokinetics and pharmacodynamics of intravenous and oral (S)‐ketamine: Investigating metabolite contribution to subjective effects

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Oral administration of (S)‐ketamine for treatment‐resistant depression (TRD), as alternative to the registered intranasal or off‐label intravenous administrations, has high potential. However, it is characterized by an extensive first‐pass metabolism, resulting in low (S)‐ketamine exposure and high levels of active metabolites, including (S ...

PPARγ-activation increases intestinal M1 macrophages and mitigates formation of serrated adenomas in mutant KRAS mice

open access: yesOncoImmunology, 2018
To identify novel hubs for cancer immunotherapy, we generated C57BL/6J mice with concomitant deletion of the drugable transcription factor PPARγ and transgenic overexpression of the mutant KRASG12V oncogene in enterocytes.

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

open access: yesBiological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Intracellular apoA-I and apoB distribution in rat intestine is altered by lipid feeding.

open access: yesJournal of Lipid Research, 1988
Intracellular forms of chylomicrons, very low density lipoprotein (VLDL) and high density lipoprotein (HDL) have previously been isolated from the rat intestine.

Immunometabolic and Spatiotemporal Control of Tissue‐Resident Memory T Cell Biology

open access: yesBarrier Immunity, EarlyView.
Tissue‐resident memory T (TRM) cells in barrier tissues provide a frontline defense against invading pathogens. Immune (Signals 1–3) and nutrient (Signal 4) cues play an integral role in directing TRM formation and heterogeneity. The spatial and temporal organization of these signals establishes durable TRM cells across tissues, enabling diverse ...

Lactoferrin and free secretory component of human milk inhibit the adhesion of enteropathogenic Escherichia coli to HeLa cells

open access: yesBMC Microbiology, 2001
Background Diarrhoea caused by Escherichia coli is an important cause of infant morbidity and mortality in developing countries. Enteropathogenic Escherichia coli (EPEC) is considered one of the major causes of diarrhoea in children living in developing ...
