23. Comparison of the morphology of the megachiropteran and microchiropteran eye

Author

Bojarski, C and Bernard, R.T.F.

Abstract

The structure of the eyes of two South African bat species, Rousettus aegyptiacus (Megachiroptera: Pteropodidae) and Rhinolophus capensis (Microchiroptera: Rhinolophidae) was examined and compared by means of light microscopy. The eyes of both species exhibit characteristics of a typical ‘nocturnal eye’ (presence pf only rods in the retina; the cornea shows a marked curvature and occupies about one third of the globe; the anterior and posterior chambers are very large in relation to the vitreous) and neither possess a fovea. The main difference occurs in the choroid and the retina. The fruit bat R. aegyptiacus shows a marked folding of the retina, as a result of papillae that project inwards from the choroid. This does not occur in the insectivorous bat R. capensis, where the choroid and the retina form a smooth layer. It is suggested that this unique feature of the fruit bat, and the associated increase in surface area and hence the number of photoreceptors is probably responsible for its good nocturnal vision.

25. Campylobacter jejuni impairs sodium transport and epithelial barrier function via cytokine release in human colon

Abstract

Campylobacter jejuni is the most prevalent cause of foodborne bacterial enteritis worldwide. Patients present with diarrhea and immune responses lead to complications like arthritis and irritable bowel syndrome. Although studies exist in animal and cell models, we aimed at a functional and structural characterization of intestinal dysfunction and the involved regulatory mechanisms in human colon. First, in patients' colonic biopsies, sodium malabsorption was identified as an important diarrheal mechanism resulting from hampered epithelial ion transport via impaired epithelial sodium channel (ENaC) beta- and gamma-subunit. In addition, barrier dysfunction from disrupted epithelial tight junction proteins (claudin-1, -3, -4, -5, and -8), epithelial apoptosis, and appearance of lesions was detected, which cause leak-flux diarrhea and can perpetuate immune responses. Importantly, these effects in human biopsies either represent direct action of Campylobacter jejuni (ENaC impairment) or are caused by proinflammatory signaling (barrier dysfunction). This was revealed by regulator analysis from RNA-sequencing (cytometric bead array-checked) and confirmed in cell models, which identified interferon-gamma, TNF alpha, IL-13, and IL-1 beta. Finally, bioinformatics' predictions yielded additional information on protective influences like vitamin D, which was confirmed in cell models. Thus, these are candidates for intervention strategies against C. jejuni infection and post-infectious sequelae, which result from the permissive barrier defect along the leaky gut.

Abstract

© 2017 by the authors. Licensee MDPI, Basel, Switzerland. Gluten-related disorders have recently been reclassified with an emerging scientific literature supporting the concept of non-celiac gluten sensitivity (NCGS). New research has specifically addressed prevalence, immune mechanisms, the recognition of non-immunoglobulin E (non-IgE) wheat allergy and overlap of NCGS with irritable bowel syndrome (IBS)-type symptoms. This review article will provide clinicians with an update that directly impacts on the management of a subgroup of their IBS patients whose symptoms are triggered by wheat ingestion.
