πŸ”† Nobel Prize 2025: Redefining the Immune System

πŸ“ Context
βœ… The 2025 Nobel Prize in Physiology/Medicine was awarded for discoveries transforming understanding of autoimmune regulation.
βœ… Laureates: Mary Brunkow, Fred Ramsdell & Shimon Sakaguchi β€” pioneers who identified regulatory T-cells (Tregs) and the FOXP3 gene.

πŸ“ Key Findings
βœ… FOXP3 acts as a molecular switch for immune self-tolerance.
βœ… Mutations in FOXP3 cause autoimmune collapse, proving its central role in immune regulation.
βœ… Their discoveries revealed how the immune system balances activation and restraint, preventing self-destruction.

πŸ“ Applications
βœ… Treg-based therapies are being tested to treat autoimmune diseases, improve graft acceptance, and enhance cancer immunity without triggering autoimmunity.
βœ… Highlights how private-sector research (Celltech Chiroscience) can drive major biomedical breakthroughs.

πŸ“˜ Challenges
βœ… Translating these insights into affordable, scalable cell therapies remains difficult due to high costs and ethical issues.

Just at this time, Bitcoin and the broader crypto market have dropped to new 2022 lows. The Bitcoin price has tanked 10 percent dropping to $20,000. On the other hand, the altcoin space is witnessing even more brutal correction. Bitcoin has dropped nearly 60 percent year-to-date and more than 70 percent since its all-time high in November 2021. Telegram offers a powerful toolset that allows businesses to create and manage channels, groups, and bots to broadcast messages, engage in conversations, and offer reliable customer support via bots. Healing through screaming therapy Ng Man-ho, a 27-year-old computer technician, was convicted last month of seven counts of incitement charges after he made use of the 100,000-member Chinese-language channel that he runs and manages to post "seditious messages," which had been shut down since August 2020. With the β€œBear Market Screaming Therapy Group,” we’ve now transcended language.
