En este primer capítulo de la **Salmon Immunology Series**, presentada por **Aqua Health by MNL Group** y su producto Futerpenol, en asociación con Pathovet Labs, comenzamos desde los fundamentos: los órganos y células que sostienen la defensa inmunológica en los peces. ## ¿Qué aborda este capítulo? A diferencia de los mamíferos, los peces carecen de médula ósea y ganglios linfáticos. Su sistema inmune descansa principalmente en la **inmunidad innata**, capaz de reconocer patógenos sin exposición previa. Los **órganos linfoides primarios** — el timo y el riñón anterior — cumplen roles esenciales: el timo participa en la diferenciación y selección de linfocitos T, mientras que el riñón anterior, con su alta capacidad hematopoyética, funciona como el análogo de la médula ósea en estos animales. Los **órganos linfoides secundarios**, como el bazo y los tejidos linfoides asociados a mucosas (MALT), se encargan de presentar antígenos e inducir respuestas inmunes adaptativas. El MALT se subdivide en tejidos asociados a la piel, branquias, intestino y órgano olfativo. La **barrera mucosa** constituye la primera línea de defensa: contiene moléculas antimicrobianas y genera microambientes que antagonizan a los patógenos antes de que estos logren penetrar. Cuando esa barrera es superada, los **receptores de reconocimiento de patrones (PRR)** detectan al agente patógeno y activan la respuesta inmune innata. ## ¿Por qué importa esto para la acuicultura? Comprender la arquitectura del sistema inmune de los salmónidos es el primer paso para tomar decisiones informadas sobre su manejo sanitario — desde el diseño de protocolos de vacunación hasta el uso de aditivos no farmacológicos que contribuyan a fortalecer sus defensas naturales. Este capítulo sienta las bases de los temas que desarrollaremos a lo largo de la serie. *Salmon Immunology Series es una iniciativa educativa de **Aqua Health by MNL Group** en asociación con **Pathovet Labs**, orientada a profesionales de la industria acuícola.* ##### Spread the word - [Share this blog post on Twitter](https://twitter.com/intent/tweet?text=I+found+this+interesting+blog+post&url=https://www.mnl-group.com/es/blog/salmon-immunology-series-capitulo-1-defensa-inmunologica-peces) - [Share this blog post on Facebook](http://www.facebook.com/share.php?u=https://www.mnl-group.com/es/blog/salmon-immunology-series-capitulo-1-defensa-inmunologica-peces) - [Share this blog post on LinkedIn](http://www.linkedin.com/shareArticle?mini=true&url=https://www.mnl-group.com/es/blog/salmon-immunology-series-capitulo-1-defensa-inmunologica-peces) ##### [Aqua Health by MNL Group](https://www.mnl-group.com/es/blog/author/aqua-health-by-mnl-group) ##### Leave a comment [![Logo MNL Group](https://www.mnl-group.com/hubfs/Logo_MNLGROUP-3.svg "Logo MNL Group")](https://mnl-group.com/?hsLang=es) Follow us and get in touch to stay up to date with our latest news.
