obtaining hemocytes from the hawaiian bobtail squid euprymna scolopes and observing their adherence to symbiotic and non-symbiotic bacteria

Estudios sobre el papel del sistema inmune en la mediación de señalización molecular entre bacterias beneficiosas y sus anfitriones tienen, en los últimos años, hizo importantes contribuciones a nuestra comprensión de la co-evolución de los eucariotas con la microbiota presente. La asociación simbiótica entre el hawaiano calamar bobtail,<em&gt; Euprymna scolopes</em&gt; Y la bacteria bioluminiscente<em&gt; Vibrio fischeri</em&gt; Se ha utilizado como un sistema modelo para entender los efectos de las bacterias beneficiosas en el desarrollo animal. Estudios recientes han demostrado que los macrófagos-hemocitos, el único componente celular del sistema inmune innato del huésped calamar, probablemente juegan un papel importante en la mediación de la creación y el mantenimiento de esta asociación. Este protocolo se mostrará cómo obtener hemocitos de<em&gt; E. scolopes</em&gt; Y luego usar estas células en ensayos de unión bacteriana. Adultos calamar son los primeros anestesiados antes de la hemolinfa se recoge con una jeringa de los vasos sanguíneos principales cefálica. Los hemocitos de acogida, contenida en la hemolinfa extraída, se adhieren a cubreobjetos de vidrio de cámara y luego se exponen a la proteína verde fluorescente marcada con simbiótica<em&gt; Vibrio fischeri</em&gt; Y no simbiótica-<em&gt; Vibrio harveyi</em&gt;. Los hemocitos son contrastados con un tinte fluorescente (celular Rastreador de Orange, Invitrogen) y luego se visualizan mediante microscopía de fluorescencia.
