Microbes start immune response by sneaking inside cells

Researchers have discovered that bacteria can enter immune system cells through a pore in the cell membrane, triggering an immune response without activating Toll-like receptors. This finding offers new perspectives for developing human vaccines and drugs that target inflammatory responses in autoimmune diseases like rheumatoid arthritis.
