Nobel Prize 2025: Nobel For Medicine Awarded To Mary Brunkow, Fred Ramsdell, Shimon Sakaguchi; Who Are They?

The 2025 Nobel Prize announcements commenced with the Medicine category. Mary E. Brunkow and Fred Ramsdell from the United States, along with Shimon Sakaguchi from Japan, were honoured with the Nobel Prize in Physiology or Medicine. This accolade was revealed by the Karolinska Institute in Stockholm. Since its inception, this prestigious award has been presented 115 times to 229 laureates between 1901 and 2024.

Their groundbreaking work on 'peripheral immune tolerance' earned them this recognition. This discovery has significantly advanced the understanding of the body's immune system. It paves the way for treating autoimmune diseases like rheumatoid arthritis, type-1 diabetes, and lupus.

Peripheral immune tolerance is a crucial mechanism that stops the immune system from attacking the body's own cells. The Karolinska Institute in Sweden acknowledged this research, which has expanded knowledge of autoimmune diseases. It also opens new avenues for treatments in immune science and cancer medicine.

The Nobel Prize in Physics will be announced on Tuesday, followed by Chemistry on Wednesday and Literature on Thursday. The Nobel Peace Prize will be declared on Friday, while the Nobel Memorial Prize in Economic Sciences is set for October 13th.
