Abstract
The cannabinoid 2 receptor (CB2R) is a crucial element of the endocannabinoid system (ECS), which is predominantly expressed on cells of the reticuloendothelial system. Alterations in CB2R expression have shown a prognostic role in various human neoplastic diseases and its expression has been studied in canine mast cell tumours (MCT). Canine diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma in dogs and has a variable clinical behaviour. Expression of CB2R was assessed by means of immunohistochemistry in fifteen dogs with proven histological diagnosis of DLBCL. A semiquantitative and quantitative assessment of immunoreactivity (IR) by digital analysis was performed in all cases. Our results indicate that CB2R expression is conserved in canine DLBCL but does not correlate with clinical outcome.
期刊介绍：
Research in Veterinary Science is an International multi-disciplinary journal publishing original articles, reviews and short communications of a high scientific and ethical standard in all aspects of veterinary and biomedical research.
The primary aim of the journal is to inform veterinary and biomedical scientists of significant advances in veterinary and related research through prompt publication and dissemination. Secondly, the journal aims to provide a general multi-disciplinary forum for discussion and debate of news and issues concerning veterinary science. Thirdly, to promote the dissemination of knowledge to a broader range of professions, globally.
High quality papers on all species of animals are considered, particularly those considered to be of high scientific importance and originality, and with interdisciplinary interest. The journal encourages papers providing results that have clear implications for understanding disease pathogenesis and for the development of control measures or treatments, as well as those dealing with a comparative biomedical approach, which represents a substantial improvement to animal and human health.
Studies without a robust scientific hypothesis or that are preliminary, or of weak originality, as well as negative results, are not appropriate for the journal. Furthermore, observational approaches, case studies or field reports lacking an advancement in general knowledge do not fall within the scope of the journal.
