It sounds simple, but this discovery is a huge deal for millions of people who suffer from conditions like Lupus, Type 1 Diabetes, and Rheumatoid Arthritis.

At Taza News, we want to break down this complex science into simple terms so you can understand why this work is so important.

The Problem: Your Immune System's Friendly Fire

Think of your immune system as an elite security force protecting a city. Its job is to spot intruders (viruses, bacteria, etc.) and destroy them. This is what it does thousands of times a day.

But what happens when this security force gets confused and starts attacking the city’s own buildings and residents? That’s what we call an autoimmune disease. It's the body turning on itself.

For decades, scientists knew how the body trained its immune cells (called T cells) in a special organ called the thymus. They thought any cell that might attack the body was eliminated there. This was the "central control." But this explanation was incomplete. A small number of "rogue" cells still escaped the training camp, and yet, most people don't develop severe autoimmune diseases. Something else had to be keeping them in check.

The Breakthrough: The Immune System's Peacekeepers

The three Nobel laureates solved this puzzle by finding the immune system’s secret set of "peacekeepers" and the master switch that controls them.

Chapter 1: The Discovery of the Security Guards (Shimon Sakaguchi)

Back in the 1990s, Dr. Shimon Sakaguchi of Japan decided to look for a different mechanism of control, one that worked outside the thymus (what scientists call "peripheral tolerance").

He discovered a brand-new type of immune cell that didn't attack invaders—it suppressed the immune system's own aggressive cells. He called them Regulatory T cells (or Tregs). These are the security guards that step in and tell the other, overzealous T cells to "calm down" and stop attacking the body’s healthy tissues. This was the first piece of the puzzle.

Chapter 2: Finding the Master Switch (Mary Brunkow and Fred Ramsdell)

A few years later, in the US, Mary Brunkow and Fred Ramsdell were studying a strain of mice that suffered from severe autoimmune diseases. After painstaking genetic research, they found a single flaw in a specific gene, which they named Foxp3. This gene defect completely disabled the mice’s ability to regulate their immune system, leading to the body’s defenses running wild.

Crucially, they realized the human version of this gene was responsible for a rare but fatal autoimmune condition in children, proving this gene was a master control for preventing self-attack.

Chapter 3: Linking the Two

Finally, Dr. Sakaguchi connected the dots. He proved that the Foxp3 gene—the master switch found by Brunkow and Ramsdell—was exactly what controlled the development and function of the Regulatory T cells—the peacekeepers he had discovered.

The whole system suddenly made sense: The Foxp3 gene tells the body to create the Tregs, and the Tregs patrol the body, ensuring the main immune army doesn't commit friendly fire.

Why This Matters for You

This isn't just a win for science; it’s a massive step forward for human health.

1. Hope for Autoimmune Diseases: In conditions like Multiple Sclerosis or Type 1 Diabetes, the patient’s Tregs are often either too weak or too few. Now that scientists understand the mechanism, they can work on therapies to boost the number of Tregs or make them more powerful. This could one day lead to cures, or at least far better treatments, than the current drugs that just broadly suppress the entire immune system.

2. Better Cancer Treatments: In some cancers, the tumors actually recruit Tregs to protect themselves from the body's own immune attack. Researchers are now looking at ways to temporarily disable or remove those Tregs near a tumor, allowing the immune system to finally fight the cancer effectively.

3. Safer Organ Transplants: When someone receives an organ transplant, the body’s immune system naturally views the new organ as an enemy and attacks it (rejection). By using Tregs, doctors hope to train the immune system to tolerate the new organ without having to rely on harsh immunosuppressive drugs that leave the patient vulnerable to infection.

The work of Brunkow, Ramsdell, and Sakaguchi has launched an entire new field of medicine. It gives millions of people battling chronic illnesses a strong reason for hope. It's a reminder that fundamental research, even on something as tiny as a T cell, can have the largest impact on human life.

The changes will take effect from October 26, 2025, aligning with the winter travel schedule. This adjustment, announced by Air India, is designed to manage the reduced domestic capacity at T3 as the terminal focuses on expanding its role as India’s primary international gateway.

The New Terminal Breakdown

Air India group airlines—which currently operate entirely from T3 for both domestic and international flights—will now be spread across all three terminals for domestic departures:

• Air India (AI): The national carrier will relocate 60 of its 180 daily domestic departures out of Delhi to the newly upgraded Terminal 2 (T2). All other domestic flights will continue to operate from T3.

• Air India Express (AIX): The low-cost subsidiary will move all its domestic operations to the newly renovated Terminal 1 (T1).

• International Flights: All international flights for both Air India and Air India Express will continue to operate exclusively from Terminal 3 (T3).

Why the Shuffle? Expanding the International Gateway

The primary driver for this major operational adjustment is the ongoing expansion of T3. T3 is currently the only terminal at Delhi Airport that handles international flights, and with international passenger traffic on a steady rise, the Delhi International Airport Ltd. (DIAL) is converting one of T3’s domestic piers into an international one.

This conversion, while essential for increasing T3’s international handling capacity to meet projected growth for the next few years, will inevitably reduce the terminal's capacity for domestic operations, making the relocation necessary.

Guidance for Passengers: Check Your Terminal

To ensure a smooth transition for the thousands of passengers affected daily, Air India is implementing several measures:

1. Flight Renumbering: Air India domestic flights operating from T2 will be renumbered into a four-digit series prefixed with ‘1’ (e.g., AI1737, AI1787). This clear distinction will help travelers easily identify that their flight departs from T2.

2. Proactive Notification: Air India and Air India Express will proactively notify all passengers with existing bookings for the relocated flights via their registered contact details (email and phone).

3. Seamless Transfers: For passengers with connecting flights (including between Air India, Air India Express, and codeshare partners) who have through-checked baggage, the airlines will provide seamless airside baggage transfer, eliminating the need to collect and re-check bags between terminals.

4. Terminal Connectivity: For all other passengers requiring transfers between T1, T2, and T3, the airport will operate a free shuttle service running every 10 minutes. Buggy rides will also be available between T2 and T3 for passengers with reduced mobility. Taza News advises all travelers to update their contact details and check their terminal information via the official airline websites or apps before heading to the airport.

This large-scale terminal reshuffle marks a significant phase in Delhi Airport’s growth, temporarily redirecting domestic traffic to prioritize the expansion of international capacity at T3, setting the stage for India to become a major global aviation hub.
