Resumen

La gacela india es oriunda de la zona silvestre del norte de Pendjab (Pakistán). De acuerdo a las categorías de la lista roja de la Unión Internacional de Conservación de la Naturaleza y los Recursos Naturales, constituye una especie en peligro. El entendimiento de la genética de la respuesta inmune en esta especie puede ser útil para diseñar efectivas estrategias de conservación. El objetivo del estudio fue evaluar la diversidad genética molecular en la interleukina 2 (IL-2), secuencias de genes que ponen en peligro a G. bennetti como un gen que codifica una citokina involucrada en algunas actividades vitales de regulación de la respuesta inmune. El gen IL-2 (492 bp) fue amplificado y secuenciado en muestras de ADN colectadas de la naturaleza, así como de ejemplares cautivos de gacela india, seguidos por la alineación y el análisis filogenético. Los vecinos que unen el árbol construido de MEGA6 mostraron que G. bennetti es distinto de otros y forma un clado diferente. El análisis de los resultados del estudio mostró que las gacelas indias constituyen una única población aislada encontrada en Pakistán, la cual es endémica y está expuesta al peligro. Por consiguiente, las técnicas de conservación in-situ y ex-situ para G. bennetti constituyen una buena alternativa para evitar el peligro de extinción de la especie.
