A depletion experiment is only as good as the depletion you can prove. Injecting a functional-grade antibody and assuming the population is gone is the most common failure mode in in vivo immunology.

Techniques · Gene DeliveryTransduction vs Transfection: Understanding Gene Delivery TechniquesTransduction and transfection are the two main routes for introducing genetic material into cells. Transdu

Regulatory T cells cannot make the cytokine they depend on. FOXP3 represses the Il2 locus, so every Treg lives on IL-2 secreted by the conventional T cells it exists to restrain. That asymmetry expla

Imagine a microscopic sniper, capable of delivering a lethal blow to a single cancer cell while leaving its healthy neighbors virtually untouched. This is the promise of targeted alpha therapy, a rev
