Quick Info Section: Key Facts About MogamulizumabWhat is Mogamulizumab?Mogamulizumab is an anti-CCR4 monoclonal antibody used primarily for treating certain cancers, including cutaneous

Almost any inflammatory phenotype in a mouse can be assigned to a cytokine by taking that cytokine away. Neutralisation is the most direct causal test immunology has: inject a functional-grade antibo

Toll-like receptors are the reason a milligram of endotoxin can kill a mouse. They are the fastest, least discriminating layer of immunity: germline-encoded sensors that read conserved microbial chem

Why do powerful cancer immunotherapies work wonders for some patients but fail for others? The answer may lie not just in the cancer cells themselves, but in the energy levels of our own immune warrio

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
