A New Dawn in Lupus Treatment: The Promise of Topical RNA Therapeutics Systemic Lupus Erythematosus (SLE) is a debilitating autoimmune disease that has long puzzled researchers and clinicians. Howeve

The inflammasome is one of the few innate pathways that destroys the cell it activates. A macrophage that assembles NLRP3 has committed to a decision it cannot reverse: a priming signal through TLR4

Imagine a battlefield where the enemy doesn't just hide from soldiers—it actively sabotages their weapons. In the tumor microenvironment, cancer cells have evolved a devious strategy: they transfer th

Transplant rejection is the fastest, most violent adaptive immune response a body can mount — and it is a response to a molecule rather than to a pathogen. Somewhere between one and ten per cent of a

Imagine a future where a simple blood test could detect cancer in its earliest stages, long before symptoms appear. This isn't science fiction; it's the rapidly advancing reality of liquid biopsy, a r

Both interferon families run through STAT1, and that single shared subunit is why they are so often conflated — and why conflating them is a mistake. Type I interferon assembles STAT1 into a three-pa
