🧬 New Year, new health goals - let’s get real: exercise fads, diets & oxygen therapies promise “blood cleansing,” but oxygen transport, circulation, cholesterol, and immune defence rely on real macromolecular complexes, not detox trends.

🌿 Why it matters
• Excess NH₄⁺ disrupts growth and cellular balance
• Species differ in ammonium tolerance, influencing biodiversity
• Human-driven nitrogen favours ammonium-tolerant species
💡 Plants aren’t passive nitrogen absorbers-they actively regulate uptake to balance nutrition and stress.

🌱 Balancing Act: Plants & Ammonium
Plants constantly adjust to shifting nitrogen levels. Ammonium transporters (AMTs) mediate NH₄⁺ uptake, redistribution, & sensing.
💡At high ammonium, AMT complexes rapidly shut down uptake via phosphorylation & later reduce AMT gene expression.

Don’t just publish - be found! 🔍
I didn’t realize how vital biocuration was until I became a curator. A well-curated dataset doesn’t just sit in a paper - it lives on in databases and fuels new discoveries.

🧬 On #GlobalPNHAwarenessDay, we spotlight the GPI-GnT complex - a key enzyme disrupted in PNH, a rare and life-threatening blood disorder.
🧩 Its failure (often via PIGA mutations) removes GPI-anchored proteins, leaving blood cells unprotected from complement attack.
