RESUMEN

El sistema respiratorio se encuentra en contacto con agentes patógenos; sin embargo, gracias a la respuesta inmune innata de éste, sólo en raras ocasiones se produce la enfermedad. Las células epiteliales del tracto respiratorio desempeñan un papel importante para evitar la colonización del pulmón por agentes infecciosos, identificando a los microorganismos a través de receptores especializados como los toll-like. Asimismo, son capaces de secretar citocinas, péptidos antimicrobianos y otras moléculas proinflamatorias, las cuales evitan el establecimiento de patógenos.
