Composite of a Scanning Electron Micrograph and Immunofluorescence Image

Caption

Composite of a scanning electron micrograph and immunofluorescence image showing a T cell (SEM) on an array of clusters of T cell receptor ligands, fluorescently labeled red. The green fluorescent signal comes from phosphorylation of a component of the T cell receptor, indicating that triggering has occurred (i.e., the T cell has been stimulated).
