Heavy functions for light chains

Immunologists are just beginning to understand the early signals required to recruit memory T cells to sites of antigen-specific inflammation. Now it seems that activation of κ light chain–sensitized mast cells by antigen-specific recognition initiates local immune responses (pages 694–701).
