Nobel Prize 2025 – Redefining Autoimmune Regulation

The 2025 Nobel Prize in Physiology or Medicine honoured Mary Brunkow, Fred Ramsdell, and Shimon Sakaguchi for discoveries that transformed understanding of immune self-tolerance. Sakaguchi revealed that beyond deletion of self-reactive T-cells during maturation, regulatory T-cells (Tregs) suppress autoimmune responses in the body’s periphery. In 1995, his team showed that removing CD4⁺ Tregs in mice caused autoimmune disease, while restoring them prevented it. Brunkow and Ramsdell’s work on scurfy mice traced severe autoimmunity to a mutation on the X chromosome, identifying the FOXP3 gene as the molecular switch for Treg development and function. Mutations in FOXP3 in humans were later linked to fatal autoimmune disorders. These findings redefined the immune system’s view from a simple on/off mechanism to a dynamic balance of activation and restraint. Current therapies aim at expanding or engineering Tregs for autoimmune and transplant applications, or selectively depleting tumour-associated Tregs in cancer. However, high costs, technical challenges, and the complexity of immune regulation hinder widespread use, while raising ethical and policy questions over equitable access.

Ensuring Compliance in India’s Pharmaceutical Sector

India’s goal of becoming self-reliant in pharmaceuticals – a key pillar of Atmanirbhar Bharat – faces serious challenges due to recurring lapses in drug quality. The recent detection of high levels of diethylene glycol (DEG) in cough syrup samples during tests by Tamil Nadu’s Drugs Control Department, following child deaths in Rajasthan and Madhya Pradesh, is the latest example. While initial Union Health Ministry tests in those states ruled out DEG contamination, one batch tested in Tamil Nadu contained it, alongside other lapses in Good Manufacturing and Good Laboratory Practices. The contaminated medicine was linked to the use of non-pharmacopoeial grade propylene glycol, which can introduce toxic substances like DEG and ethylene glycol. The Central Drugs Standard Control Organisation has moved to cancel the manufacturer’s licence, and a doctor who recommended the syrup to many affected children has been arrested. Authorities stress the need for zero tolerance toward poor-quality drugs, with strict enforcement, surprise inspections, and immediate action on violations before fatalities occur, sending a clear message that public health cannot be compromised.

Spurious Cough Syrup Deaths – A Wake-up Call for Pharma Regulation

The deaths of at least 14 children in Madhya Pradesh’s Chhindwara district and in Rajasthan from Coldrif cough syrup contamination highlight India’s grave pharmaceutical regulatory failures. The syrup contained 48.6% diethylene glycol (DEG), a toxic industrial solvent far above the WHO limit of 0.10%, and was given for common ailments. Similar tragedies have occurred elsewhere — from Cameroon (2023) to Gambia and Uzbekistan (2022), and Jammu & Kashmir (2020) — showing a global pattern of preventable deaths involving poor-quality drugs. India’s pharmaceutical industry, hailed as the “pharmacy of the world” for its global supply of generics, suffers from weak oversight, especially in small-scale production units. In 2023-24, 36% of inspected manufacturing units were shut for serious violations, yet many others escape scrutiny. State regulators, with limited resources and autonomy, fail to ensure timely pharmacovigilance, as officials in MP admitted being unaware of the ongoing crisis for weeks. Past scandals have seen little accountability, with implicated companies facing minimal legal consequences. The MP deaths underline the urgent need to strengthen inspections, enforce manufacturing compliance, and restore public trust in India’s drug quality.

Nobel Prize Work Unlocks Key to Immune Regulation

Mary Brunkow, Fred Ramsdell, and Shimon Sakaguchi have jointly won the 2025 Nobel Prize in Physiology or Medicine for pioneering discoveries on how the immune system prevents attacking the body’s own cells. Their research focused on T-cells, a type of white blood cell crucial for defending against pathogens. Sakaguchi identified regulatory T-cells (Tregs), which suppress harmful T-cell activity and protect healthy tissues. Brunkow and Ramsdell discovered the FOXP3 gene enabling certain T-cells to function as Tregs, completing the picture of immune self-tolerance. These insights have major implications: in autoimmune diseases, modulating Tregs can reduce self-damage; in organ transplants, managing Tregs could prevent rejection; and in cancer treatment, limiting tumour-attracted Tregs may empower immune cells to fight cancer effectively. This foundational work continues to shape research in disease management and immunotherapy
