Research Group(s):

Donald is a Senior Lecturer in Comparative Biomedical Sciences. His main research interests are immunosenesence, particularly with regards to age-associated thymic involution. He is also interested in the use of antibody phage display technology to identify novel markers on stem cells and cancer cells.


Biography

Donald is a Senior Lecturer in Immunology. He did his undergraduate studies (Medical Sciences) at Bradford University, his postgraduate studies (MSc in Immunology) at King's College London and obtained his PhD which involved investigating the genetic regulation of Beta-2-microglobulin in the Division of Transplantation Biology, MRC Clinical Science Centre, Northwick Park Hospital.

This was followed by a post doctoral position at Cancer Research UK, looking at lymphocyte development in transgenic and mutant mice in the laboratory of Dr Mick Owen. Donald undertook another post doctoral position at Imperial College in the laboratory of Professor Mary Ritter, again working in the area of lymphocyte development, but in the context of the microenvironment. Donald successfully obtained an MRC Career Development Award and became a Research Lecturer at Imperial College London. During this award he used antibody phage display technology to study cellular interactions in the thymus and investigated intrathymic neuroendocrine communications. He joined the RVC in 2002.

Donald is currently a member of the British Society for Immunology (BSI), was Secretary of the London Immunology Group (a Regional Group of the BSI; 2002-2007) and now a board member of the BSI council. He is also a member of the British Society for Research on Ageing.

Donald is currently a Senior Honorary Lecturer at Imperial College, London

Research

Donald’s main area of research is focused on investigating the cellular and molecular interactions involved in T cell development and in particularly understanding the processes that are involved in age-associated thymic involution and immunosenescence.

He has used antibody phage display technology to identify cell surface structures expressed on thymic epithelium that are involved in stromal cell-thymocyte interaction; which is still an ongoing project. Furthermore, in a collaborative project he has used this technology to identify cell surface structures on tumours. Cross-talk between the immune, endocrine and nervous systems involve common neuroendocrine circuits and Dr Palmer’s work has demonstrated the expression of several neuropeptides and their receptors in the thymus of different species and showed that these peptides can directly modulate thymocyte differentiation.

These studies led Dr Palmer to pursue an interest in understanding how ageing affected the immune system, in particular the mechanisms involved in age-related thymic atrophy. He’s group have been investigating the architectural changes in the ageing thymus, and made the novel finding of the presence of senescent cells in the thymus of older animals (in collaboration with Professor Thomas von Zglinicki, Institute of  Ageing and Health, University of Newcastle). In addition to these observations, examination of thymocytes also revealed age-related alterations in phenotype and function. Dr Palmer has extended his interest on the affect of ageing on other components of the immune system and is examining Natural Killer cell function in the elderly (in collaboration with Prof Arne Akbar and Dr Sian Henson, UCL).

He also has an interest in comparative immunology and is currently examining the thymic architecture and function in different species.

Donald currently organises the college’s external seminar programme (2003-present).
