For generations, the treatment of depression has been a slow and imprecise art, asking suffering people to wait weeks for relief while accepting the limitations of imperfect medicines. Now, scientists have mapped the precise cellular pathways through which ketamine lifts the weight of depression — not through the neurotransmitter channels long assumed to govern mood, but through the brain's own immune cells. This discovery, made at the intersection of psychiatry and immunology, offers something rare in medicine: not just a better drug, but a fundamentally clearer understanding of what depressi
