Cecilia Ley
I am a veterinary pathologist, researcher and senior lecturer in veterinary pathology at SLU. I am fascinated by the subject of pathology (the doctrine of our diseases) and my work aims to increase our knowledge of causes and mechanisms of disease in animals. Through increased disease knowledge, preventative disease strategies, improved methods for diagnosis and treatment can be developed. I am also program director for the specialist education in veterinary pathology at SLU.

Presentation

As a veterinary pathologist, I have a broad interest in animal diseases, but I am particularly interested in diseases that affect companion animals. As a specialist in veterinary pathology, I have broad knowledge in the subject and can contribute with expertise in several different contexts. In addition to research and teaching, my employment at SLU includes performing diagnostic pathology on biopsies from patients seen at the University Animal Hospital and the Ambulatory Clinic at SLU. I thoroughly enjoy teaching both at undergraduate and postgraduate level, and I think it is especially rewarding when teaching and research is linked, for example through students' degree projects. 

Teaching

I teach in the courses Special Pathology and Diagnostic Pathology, and I have been course leader for Special Pathology in the Veterinary program for many years. The teaching has mainly involved necropsies, diseases of the endocrine system, neuropathology and histopathology. Further, I am mentor for veterinarians who participate in specialist training in pathology at BVF.

Research

My current research is focused on diseases of cats and dogs. I lead projects about the joint disease osteoarthritis in cats and encephalitis in dogs. I also work in projects aiming to increase our knowledge about chest malformations in Bengal cats, and 'staggering disease' and diabetes mellitus in cats. 

In my research on osteoarthritis in cats, underlying causes, disease development and how the diagnosis of the disease can be improved are investigated. I am mainly interested in how inflammation and metabolic parameters (such as body fat and bone density) are related to osteoarthritis. In the latest project, "Mechanisms of joint disease in cats - from whole body examination to molecular changes", the focus is on associations between osteoarthritis and bone-stimulatory substances. In the studies, whole-body computed tomography is combined with different types of tissue examinations. 

In the project "Genetic background to flat chest in Bengal cats", the goal is to determine the genetic defect/s associated with malformation of the chest.

In collaboration with colleagues from Sweden and Germany I have ongoing research on 'staggering disease' in cats. 'Staggering disease' is a serious infectious disease that causes inflammation of the brain and spinal cord.

The research on encephalitis in dogs is a collaboration between SLU, the Swedish Veterinary Agency (SVA), Uppsala University, Ludwig Maximilian University and Friedrich-Loefller Institute. The studies aim to increase our understanding of encephaliltis in dogs, investigate known and so far unknown viruses as causes and to perform comparative studies to people.

Background

After my veterinary degree in 1994, I worked for a few years as a clinic veterinarian in Sweden and abroad (Great Britain and Australia).

In 2003 I started a postgraduate position in pathology at SLU, focusing on the role of inflammation in osteoarthritis in horses. In 2010 I defended my thesis "Inflammatory Response in Equine Joints - Studies on Proinflammatory Cytokines in Diseased Joints and Chondrocyte Cultures".
