Peter C. Doherty – Podcast

Nobel Prize Conversations

“This is the first time we have had a completely novel virus infection and we are trying to vaccinate our way out of it”

In this conversation, conducted in January 2021, immunologist Peter Doherty speaks about how we should learn from the current corona pandemic to be better prepared for and preferably prevent future pandemics.

The host of this podcast is nobelprize.org’s Adam Smith.

Nobel Prize Conversations was produced with the support of 3M, ABB, Ericsson and Scania.

Speed read: Double-checking cells

Viruses, such as those that cause the common cold or flu, are a particularly devious form of intruder to tackle. Once they enter their host, these infectious agents find cells to hide in while they reproduce in order to infiltrate more targets. Fortunately for us our internal defence system has a trick up its sleeve to seek out this hidden threat. It recruits a specialized form of white blood cell, T killer lymphocytes, that can identify and destroy virus-infected cells, and yet can somehow leave normal healthy cells unharmed.

Investigating how this form of virus scan works turned out to provide profound insights into how the immune system functions at the cellular level, and it is for these achievements that Peter Doherty and Rolf Zinkernagel received the 1996 Nobel Prize in Physiology or Medicine. Investigating how mice are protected against infection from a viral agent that can cause the disease meningitis, they were surprised to find that virus-killing T lymphocytes taken from a mouse could only execute their destructive effect in infected cells belonging to the same strain. Doherty and Zinkernagel proposed that lymphocytes ignored infected cells in other strains because they need to simultaneously recognise two distinct signals on their suspected target – a specific molecule belonging to the concealed virus, and a specific protein marker found on all host cells that signifies that it belongs to itself. Closer inspection revealed that the virus’ molecule actually distorts the host’s marker protein by attaching to it, and this altered self protein informs the T lymphocytes that the cell is infected.

Doherty and Zinkernagel’s findings finally unmasked the true purpose of these self-recognition protein molecules, the major histocompatibility antigens. As early as the 1940s, researchers investigating adverse effects in organ transplants had pointed out that the body rejects foreign, incompatible tissues by recognizing that they carry different versions of the major histocompatibility antigens from their own. Why these proteins create a barrier to transplantation was far from obvious, but the discoveries of Doherty and Zinkernagel revealed that this is merely an unavoidable side-effect of their true biological function. Acting as a surveillance system to distinguish self from non-self, these major histocompatibility antigens allow immune cells to make their crucial life-or-death decision in the face of numerous threats.

Rolf M. Zinkernagel’s speech at the Nobel Banquet, December 10, 1996

Your Majesties, Your Royal Highness, Ladies and Gentlemen,

May I express Peter Doherty’s and my own gratitude for having been chosen among many immunologists to share this true high point in our careers as researchers, and may I convey our admiration and respect to Alfred Nobel who died 100 years ago. This is a very special day to commemorate.

When I arrived in Canberra in 1973, Peter Doherty greeted me with the usual Australian confusion: Switzerland? I know, sure, I like Sweden, I sure would once like to go to Stockholm. That we are now both together with our families and mentors here in Stockholm gives us the greatest pleasure of our life.

Why are we both in Stockholm? I suppose because Peter and I, as young 30-year old post-docs had no fixed ideas about the immunological mechanisms at work and little respect for dogmas.

As you know, in science there are collectors, classifiers, compulsory tidiers-up and permanent contestors, detectives, some artists and many artisans, there are poet-scientists and philosophers and even a few mystics. Peter is a Celt and a true Australian and to the chagrin of his wife and of mine, he is a mystic. I am very Swiss and to the chagrin of my family, I am a true collector. We are both a bit crazy, which is necessary, but not sufficient to do science but – we think – that we are both kept reasonably sane by our wives, children and collaborators.

To ask questions, to search for answers, to do research – I mean re-search in nature, what is already there, but has not been revealed so far is the most fascinating and the most exciting thing we can dream of doing and what we would like to continue doing. We researchers are a bit like musicians – and the Nobel Foundation and this assembly tell us we are reasonably good musicians – who are re-creating as best as possible what true creators, as a Mozart or Rossini once have conceived. Peter, let us face it: We have been very lucky! Had we not found the rules of restricted immune T cell recognition, somebody else would have later. Without Isaak Stern or Luciano Pavarotti, we would still have Mozart’s violin concerto or Don Giovanni, but we all recognise that without Mozart The Enchanted Flute would not exist.

To have had the unique chance to find something we did not know before and to be recognised for this here today is a great moment for both of us.

We thank the Nobel Foundation for bestowing this prize upon us. This honours not only us, but basic research and a high human good that needs our full support. That is the urge to find out more about the basic principles of nature and disease.
