Ten Feizi

She is a Fellow of the Academy of Medical Sciences, the Royal College of Physicians and the Royal College of Pathologists. In May 2021 she was elected Fellow of the Royal Society.

Feizi showed that during both cellular differentiation and the transformation of normal cells to tumorous cells, anti-li blood group antibodies could be used to track changes in glycosylation. She studied the ability of animal lectins to bind to oligosaccharides. Her interest in both the structure and recognition of glycans led her to develop a new glycan screening protocol. Feizi created the neoglycolipid (NGL)-based oligosaccharide microarray system, which allowed her to explore the whole spectrum of glycans, specific cells and glycoproteins. In 2002 her system was the first to encompass entire glycomes. Her glycoarray system, which is supported by the Wellcome Trust, is one of the world's most diverse, which allows better understanding of host–pathogen interactions and the interactions between glycans and proteins in disease processes. The system was used to assign the host-cell receptors in SV40 and Influenza A virus subtype H1N1.

In 1973 Feizi joined the Medical Research Council Clinical Research Centre, where she was appointed Head of the Glycoconjugates Section. She eventually established the Imperial College London Glycosciences Laboratory. She was made a Professor at Imperial College London in 1994.

Ten Feizi FMedSci FRS (born in 1937) is a British molecular biologist who is Professor and Director of the Glycosciences Laboratory at Imperial College London. Her research considers the structure and function of glycans. She was awarded the Society for Glycobiology Rosalind Kornfeld award in 2014. She was also awarded the Fellowship of the Academy of Medical Sciences in 2021.

Born in Nicosia, Cyprus in 1937 to a Turkish Cypriot family, Feizi completed her primary and secondary education in Cyprus before moving to London to continue her studies. She studied medicine at the Royal Free Medical School, and graduated with distinction in 1961. After qualifying as a doctor, Feizi worked as a registrar in surgery and haematology at the Hammersmith Hospital. During her placement at the Hammersmith, Feizi became interested in atypical pneumonia. Almost one third of patients who suffer from atypical pneumonia develop cold agglutinins in their blood, which are misdirected antibodies that bind to red blood cells. She demonstrated that mycoplasma can stimulate the production of auto-antibodies on binding to red blood cells. She earned her MD degree at University College London, where she researched mycoplasma pneumoniae. As an early career researcher, Feizi joined the Columbia University Vagelos College of Physicians and Surgeons as an College of Physicians and Surgeons of British Columbia Fellow, where she worked with Elvin A. Kabat on glycans. She was later appointed a research fellow at Rockefeller University, where she extracted carbohydrates in the laboratory of Richard Krause.
