Visit our science section to explore some of the most important sciences behind biotechnology and medicine including: Immune checkpoint inhibitors. Checkpoint inhibitors are drugs that help release the brakes cancer cells put on the immune system to prevent their destruction. This is usually achieved with an antibody which is used to block certain proteins carried on the surface of cancer cells that prevent their recognition by the immune system and hence their destruction. In 2015 Jimmy Carter, the former president of the US, announced he was free of melanoma that had spread to his liver and brain. He had improved following treatment with an immune checkpoint inhibitor drug. How do checkpoint inhibitors work? Such therapy is designed to block the biological pathways cancer cells use to disguise themselves from the immune system and prevent their destruction. Immune checkpoint inhibitors are now considered one of the most promising avenues for the treatment of advanced cancer. Their development grew out of research to understand the regulation of immune responses. Click here to learn more about immune checkpoint inhibitors.
Ever wanted to tread in the footsteps of scientists to understand how they come up with new ideas in the laboratory and translate these into new products for patients? You can do this by visiting our special exhibitions section. Using photographs, laboratory notebooks and other historical sources, these exhibitions bring to life some of this process. See for yourself some of the ups and downs the scientists have faced along the way.
One of the most important tools in biotechnology and medicine today is DNA sequencing, invented by Frederick Sanger, a British biochemist. This exhibition follows the journey of Sanger starting in the 1940s when he began looking for ways to decipher the composition of proteins through to his development of DNA sequencing in the 1970s. Come see the time-consuming and painstaking steps Sanger went through to perfect the DNA sequencing technique and the many different areas of medicine where DNA sequencing is now being applied all the way from the Human Genome Project through to cancer and antimicrobial resistance.
A third of all new medicines introduced into the world today are monoclonal antibodies, many of which go on to become blockbuster drugs. This exhibition is the story of how one specific monoclonal antibody, the oldest humanised monoclonal antibody created with therapeutic potential, moved from the laboratory bench through to the clinic and the impact it has had on patients' lives. The antibody, which originated from the CAMbridge PATHology family of antibodies, started life in 1979 not as a therapeutic, but as a laboratory tool for understanding the immune system. Within a short time, however, the antibody, YTH66.9, was being used to improve the success of bone marrow transplants and as a treatment for leukaemia, lymphoma, vasculitis, organ transplants and multiple sclerosis. Highlighting the many twists and turns that this monoclonal antibody took over time, this exhibition explores the multitude of actors and events involved in the making of a biotechnology drug.
Today monoclonal antibodies are indispensable to medicine. They are not only used as therapeutics, comprising six out of ten of the best selling drugs in the world, but are also critical to unravelling the pathways of disease and integral components of diagnostic tests. Yet, the story of how these unsung microscopic heroes came into the world and helped change healthcare remains largely untold. The journey of monoclonal antibodies all started when an Argentinian émigré called César Milstein arrived at the Laboratory of Molecular Biology in Cambridge, the same laboratory where Watson and Crick discovered the structure of DNA. This exhibition tells the story of how Milstein came to develop monoclonal antibodies and demonstrated their clinical application for the first time.
Exploring the lives and works of the leading people from across the world like Joseph Sinkovics (pictured) whose efforts have helped build biotechnology into a world changing science. Joseph Sinkovics (Born: 1924) Sinkovics was one of the first scientists to recognise the possibility of immortalising a specific antibody-producing cell by fusion with a lymphoma cell, the principle that underlines the generation of monoclonal antibodies today. He has also been a major pioneer in cancer research, being one of the first to discover large granular lymphocytes could kill cancer cells without pre-immunisation of the host and that attenuated (weakened) viruses could destroy tumour cells in vitro which led to his development of some of the first viral therapies against cancer.

Exploring the places and institutions, and people working in them, across the world like Wistar Institute (pictured) where the science of biotechnology has been developed. America's first non-profit independent research institution, the Wistar Institute played an important role in the development of monoclonal antibodies and is today renowned for its cancer research and vaccine development.

The untold story of monoclonal antibodies
Yale University Press has announced the publication of The Lock and Key of Medicine: Monoclonal Antibodies and the Transformation of Healthcare by Lara V. Marks (Yale University Press, Amazon). Forty years ago, viable monoclonal antibodies, imperceptibly small 'magic bullets', became available for the first time. First produced in 1975 by César Milstein and Georges Köhler at the Laboratory of Molecular Biology in Cambridge, England (where Watson and Crick unraveled the structure of DNA), Mabs have had a phenomenally far-reaching effect on our society and daily life. The Lock and Key of Medicine is the first book to tell the extraordinary yet unheralded history of monoclonal antibodies, or Mabs. Though unfamiliar to most nonscientists, these microscopic protein molecules are everywhere, quietly shaping our lives and healthcare. They have radically changed understandings of the pathways of disease, enabling faster, cheaper, and more accurate clinical diagnostic testing.
Historian of medicine Lara V. Marks recounts the risks and opposition that a daring handful of individuals faced while discovering and developing Mabs, and she addresses the related scientific, medical, technological, business, and social challenges that arose. She offers a saga of entrepreneurs who ultimately changed the healthcare landscape and brought untold relief to millions of patients. Even so, controversies over Mabs remain, which the author explores through the current debates on their cost-effectiveness.
Engineering Health: How Biotechnology Changed Medicine
The Royal Society of Chemistry has announced the publication of Engineering Health: How Biotechnology Changed Medicine edited by Lara V. Marks (The Royal Society of Chemistry). Written in an accessible style, experts trace the development of biotechnologies like stem cells, gene therapy, monoclonal antibodies and synthetic biology and how these are reshaping the diagnostic and therapeutic landscape.
Building on material from this website, this book shows the challenges behind the application of biotechnology to medicine. With medicines increasingly shifting from small organic molecules to large, complex structures, such as therapeutic proteins, drugs have become more difficult to make, administer and regulate. This book will intrigue anyone interested in the past, present and future of how we engineer better health for ourselves. The rise of biotechnology has major implications for how and where drugs are manufactured, the cost of medicine and how far society is prepared to go to combat disease.
Celebrating the first publication of monoclonal antibodies
It is now over 40 years since César Milstein and Georges Kohler published their technique for producing monoclonal antibodies. To celebrate the occasion we invite you to watch the film Un Fuegito about the life and work of Milstein, produced by Ana Fraile, Pulpofilms. The film, which you can find on vimeo.com, has been released to help raise funds for a new educational film to promote greater understanding about monoclonal antibodies and how they have transformed the lives of millions of patients across the world.
The Debate: Genome editing
Scientists have recently begun to adopt a new technique for genetic engineering, called CRISPR-Cas9, in a wide number fields ranging from agriculture to medicine. Part of its attraction is that it permits genetic engineering on an unprecedented scale and at a very low cost. The technique is already being used in a variety of fields (click here for more information about CRISPR-Cas9). But because of its potential to modify DNA in human embryos, it has prompted calls for a public debate about where the technology should be applied. Researchers working with WhatIsBiotechnology.org recently ran a pilot survey to gather people's views on the new technology. Dr Lara Marks, Managing Editor of WhatisBiotechnology.org and historian of medicine and Dr Silvia Camporesi, bioethicist at King's College London, led the project. Some 567 people contributed to the debate. The analysis of their contributions is available on this page.
We are working on a number of new and exciting projects with highly talented partners and collaborators that we plan to launch in the latter part of this year and next year. These projects include an examination of the role of women in healthcare and the life sciences, a project about conquering hepatitis B and an in-depth exploration of the new sciences around cancer immunotherapy.
