Cornelis Joseph Maria Melief (born 20 January 1943) is a Dutch immunologuist[1] specialising in cancer immunology and immunotherapy, with a focus on therapeutic cancer vaccines. He is emeritus Professor, former head of the Department of Immunohematology and Blood Transfusion at the Leiden University Medical Center,[1] and Chief Scientific Officer at ISA Therapeutics in Netherlands.[2] He is known for his work in the field of cancer immunology,[1] devising new cancer therapies based on the activation of the patient's own immune system.
In 1975, he joined the Netherlands Red Cross Blood Transfusion Service, as Head of Department of cell-mediated immunology. From 1975 to 1985 he became a scientific staff member of the CLB Amsterdam. In 1976, Melief was made head of the new Department of Experimental Tumour Immunology which in 1982 was renamed the Department of Cellular Immunology.
From 1985 to 1991, he worked as the Head of the Division of Immunology at the Netherlands Cancer Institute[3] in Amsterdam. In 1991, he became head of the Department of Immunohematology and blood transfusion at Leiden University Medical Center. In 2004 he co-founded and became Chief Scientific Officer at the Biotech company Immune System Activation (ISA) Pharmaceuticals[2]
He is author of more than 550 peer-reviewed publications, cited over 71,000 times[4] and inventor on more than 30 patents and patent applications.
Major patents include:
2003- Induction of anti-tumor CTL immunity through in vivo triggering of 4-1BB and/or CD40[5]
2007 - Long peptides of 22-45 amino acid residues that induce and/or enhance antigen specific immune responses[6]
Major publications include:
1998 - Published T-cell help for cytotoxic T lymphocytes is mediated by CD40–CD40L interactions which was a breakthrough in the understanding of the importance of helper T-cells in priming cytotoxic T lymphocytes.[7]
2009 - Published that therapeutic vaccination with long peptides caused complete or partial regression of premalignant lesions caused by human papilloma virus type 16 (HPV16).[8]
2020 – Published that strong vaccine responses against HPV16 oncogenic proteins in patients with late stage cervical cancer during chemotherapy are associated with prolonged survival.[9]
Chairman of the Dutch Society for Immunology from 2001 to 2008.
Member of the Scientific Advisory Board of NCT, a Translational and Clinical Oncology Center of excellence of the German Cancer Institute (Deutsches Krebs Forschungs Zentrum) in Heidelberg and the Comprehensive Cancer Center of University of Dresden from 2015 to present.
