These are surface proteins on antigen-presenting cells that provide crucial co-stimulatory signals to naive T cells, enabling their activation. The B7 molecules on dendritic cells binding to CD28 on T cells is a key example.
Proteínas de superficie celular en células presentadoras de antígenos que entregan señales coestimulatorias a las células T vírgenes. Ejemplos son las moléculas B7 en las células dendríticas, que son ligandos para CD28 en las células T vírgenes.
