On this day in 1982 Nobel Prize laureate James Allison published a paper in the Journal of Immunology identifying the protein structure of the T cell receptor, the previously mysterious ignition switch for immune response.

His research led to a pioneering approach for treating cancer patients by using the body's own immune system.

Data from Merck and Moderna’s phase 3 clinical trial for an mRNA-based skin cancer vaccine were leaked and then spread on social media last week, prompting the pharmaceutical companies to release an early look at the results of the trial.

The results, which triggered a drop in Moderna’s stock, are positive, experts say. The findings are “really encouraging,” says Karen Knudsen, CEO of the nonprofit Parker Institute for Cancer Immunotherapy. This kind of mRNA cancer vaccine was “fiction” 10 years ago, she says. https://www.scientificamerican.com/article/heres-what-modernas-latest-mrna-cancer-vaccine-data-actually-show/

In the 20th century polio was one of the most worrying childhood diseases with epidemics in a large number of cities. Today polio is almost eradicated thanks to a safe and effective vaccine.

The virus causing polio was discovered in 1908 by Karl Landsteiner and Erwin Popper. Landsteiner was later awarded a Nobel Prize for another discovery – that of human blood groups.

Later, in 1949, Enders, Weller and Robbins showed how to produce large quantities of the virus and was awarded the 1954 ‪‎Nobel Prize in Physiology or Medicine. Jonas Salk applied the Enders-Weller-Robbins technique and developed a polio vaccine in 1952.

Visualising the 3D structure of a polio vaccine was enabled by yet another Nobel Prize awarded discovery. Cryo-EM, or cryo-electron microscopy, allows scientists to see intricate details in biological structures. Jacques Dubochet, Joachim Frank and Richard Henderson were awarded the 2017 chemistry prize for their work developing the technique.

Nature Reviews Disease Primers: Birt–Hogg–Dubé syndrome is an autosomal dominant tumour predisposition disorder caused by pathogenic variants in the gene encoding folliculin. In this Primer, the authors describe the epidemiology, mechanisms, diagnosis and management of Birt–Hogg–Dubé syndrome, and highlight patients’ quality of life, and questions for future research.
