Celebrated Scientists Awarded For Breakthroughs In Immune Research

Andrea Ablasser along with Glen Barber and Zhijian Chen recognized for pivotal discoveries in immune response mechanisms.

On March 14, 2025, the prestigious Paul Ehrlich and Ludwig Darmstaedter Prize was awarded to three eminent scientists—Dr. Andrea Ablasser, Glen Barber, and Zhijian Chen—for their groundbreaking research on the immune system. The accolade was presented at the historic Paulskirche in Frankfurt, marking not just recognition of their achievements but also signaling the potential for transformative therapies aimed at treating infections and cancer.

Dr. Andrea Ablasser, who was born on July 13, 1983, and raised in Buchloe, is currently a professor at the École polytechnique fédérale de Lausanne (EPFL) in Switzerland. Her academic path has been stellar, with medical studies at the Ludwig-Maximilians-University (LMU) Munich beginning in 2001, where she also earned her doctorate. After completing her postdoctoral studies, she moved to Bonn and finally to Lausanne, where she has been leading significant research efforts. Ablasser's accomplishments have also included winning the Nachwuchspreis of the Paul Ehrlich and Ludwig Darmstaedter Prize back in 2014 and the German Cancer Prize in 2021.

This most recent honor—the Paul Ehrlich and Ludwig Darmstaedter Prize, endowed with 120,000 euros—recognizes the trio's extensive research elucidation of the cGAS-STING signaling pathway. This signaling pathway plays a pivotal role within the immune response mechanism, particularly when DNA is detected where it shouldn't be, such as during infections or cancerous activity. The significance of their findings lies not only in theoretical knowledge but also extends to practical applications, opening pathways for new pharmaceutical developments.

“With the discovery and mapping of the cGAS-STING signaling pathway, the award winners have opened up completely new avenues for drug research,” noted Thomas Boehm, chairman of the Paul Ehrlich Foundation, during the award presentation.

During the course of their work spanning from 2008 to 2013, Ablasser, Barber, and Chen displayed remarkable perseverance. Initially uncertain of the sweeping therapeutic possibilities their research could yield, they remained steadfast and ventured to identify the intricacies of how human cells react when they find foreign DNA. Their efforts laid out the very foundations of the innate immune response, likened to alarm systems alerting the body to intrusions by pathogens.

“We have developed the ability for the body to recognize DNA from pathogens and engage the immune system effectively,” said Ablasser, detailing the scientific ingenuity behind their research. The trio's findings also included identifying how this response can become counterproductive, leading to autoimmune conditions when the immune system turns against the body itself.

Adding to the conversation, Barber emphasized, “We started with the significance it has for combating viral infections. We can develop drugs to amplify this signaling chain,” elaborated on how their research facilitates the potential for medicines targeted against infections and providing effective vaccine responses. He also underscored the therapeutic routes for conditions like cancer, hinting at creating agents to bolster anti-tumor immunity.

With approximately 20 experimental drugs currently under development targeting various facets of this freshly mapped signaling pathway, the outlook for more effective treatments is bright. Pharmaceutical companies are actively engaged, testing these new therapies aimed at outsmarting tumor cells, which often evade immune detection.

The Paul Ehrlich and Ludwig Darmstaedter Prize, established since 1952, stands as one of the most respected awards within the medical research community. It has been awarded to 128 scientists, many of whom later received Nobel Prizes, underlining its significance and the high expectations placed upon its winners.

The event, marked by notable academic figures and public interest, aligned with Paul Ehrlich’s birthday, emphasizes the continued importance of medical research and recognition of innovative contributions. The ceremony welcomed attendees interested in the pivotal role of immunology, and those seeking to engage with leading scientific minds.

Dr. Ablasser’s commitment to her work is mirrored by her multifaceted life, balancing her roles as both scientist and mother of two. Her skillful navigation of her responsibilities speaks to the realities faced by many women and families within the research community. “It requires considerable organization,” she reflected, indicative of the challenges many working parents face. Her husband’s support and the aid of family allow her the flexibility necessary to pursue her demanding career, including her research expeditions across several continents.

The future shines bright for Ablasser and her colleagues, not just from recognition through awards but also from their leading role as pioneers unlocking pathways for treatment not previously possible. Her life's work serves as inspiration, pointing toward not just the hope of curing diseases but redefining how we understand and react to bodily threats.

Through this awarding ceremony, the world is reminded of the vibrant and life-changing nature of scientific inquiry—the kind led by people like Andrea Ablasser, Glen Barber, and Zhijian Chen. With determination and ingenuity, their work ensures the horizon of medical advancements continually expands, promising new avenues for tackling health challenges across the globe.
