Alongside the intestinal border, dendritic cells (DCs) sample large amounts of endogenous and potentially pathogenic antigens followed by initiation of protective immune responses or induction of tolerance. Breakdown of oral tolerance towards commensal bacteria is suggested to be crucial for the development of both human and canine inflammatory bowel(More)
Multicentric lymphomas, usually of B-cell origin, are rather common neoplasms in pigs, which usually affect lymph nodes and different organ systems. An uncommon manifestation of malignant lymphoma represents neoplastic peripheral nerve involvement, which has been reported in human medicine. So far, only single cases of lymphoma with manifestation in(More)
A male Angler-Red Holstein crossbred calf was almost completely hairless since its birth. Hair growth was not observed within the course of its life, but with increasing age the hair structure changed from a thin and soft hair to a wiry to coarse hair fibre. Growth rate of the animal was reduced, body condition was poor but appetite was good. In addition,(More)
Intestinal immune regulation including development of oral tolerance is of great importance for the maintenance of intestinal homeostasis. Concerning this, regulatory T cells (Tregs) occupy a pivotal role in cell-mediated immunosuppression. Dysregulation of mucosal immunology leading to an abnormal interaction with commensal bacteria is suggested to play a(More)
An 8-week-old puppy was presented to the clinic because of anorexia, polyuria, polydipsia and azotemia. The urinary sediment displayed large amounts of protozoan-like organisms, which could be identified by PCR as Encephalitozoon cuniculi genotype I. In the immunofluorescence antibody test (IFAT) an antibody titer against E. cuniculi of 1  :  2560 was(More)
Histamine is an important mediator of many physiological processes including gastrointestinal function that acts via four different histamine receptors (H1R to H4R). Elevated histamine levels and increased HR messenger ribonucleic acid (mRNA) have been shown in humans with gastrointestinal disorders such as irritable bowel syndrome or allergic intestinal(More)
A cutaneous mass in the neck was excised in a 13-year-old cat. Histopathological examination of the resected tissue revealed a multicentric squamous cell carcinoma in situ resembling Bowen's disease of man. The tumor showed a multifocal transformation to an infiltrative squamous cell carcinoma. Histological and immunohistological findings excluded actinic(More)
