Tuttavia, alcune delle malattie attuali ci spaventano ancora. Nonostante i miglioramenti delle tecniche mediche, la cura per molte malattie rimane un mistero. \u00c8 il caso dell'HIV.<\/p>\n<p>Gli scienziati di tutto il mondo hanno cercato di decodificare il virus dell'HIV per capire come combatterlo. Dopo anni di piccoli passi verso la cura, sembra che sia necessario fare un passo indietro e guardare al passato del virus.<\/p>\n<p><a href=\"https:\/\/mindthegraph.com\/\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter wp-image-5936 size-full\" src=\"https:\/\/blog.mindthegraph.com\/wp-content\/uploads\/2016\/06\/hiv-in-the-blood.jpg\" alt=\"Virus HIV\" width=\"720\" height=\"350\" srcset=\"https:\/\/mindthegraph.com\/blog\/wp-content\/uploads\/2016\/06\/hiv-in-the-blood.jpg 720w, https:\/\/mindthegraph.com\/blog\/wp-content\/uploads\/2016\/06\/hiv-in-the-blood-300x146.jpg 300w\" sizes=\"(max-width: 720px) 100vw, 720px\" \/><\/a><\/p>\n<p><a href=\"http:\/\/www.bbc.com\/earth\/story\/20151119-we-know-the-city-where-hiv-first-infected-a-human?ocid=fbert\">Nuno Faria e i suoi colleghi<\/a> dell'Universit\u00e0 di Oxford stanno studiando la nascita di una malattia che non muore mai nel tentativo di sviluppare una cura. Nel corso delle loro ricerche, sono state scoperte cose curiose sul virus dell'HIV.<\/p>\n<p>Dopo aver raccolto campioni da 800 persone infettate dal virus HIV in Africa, Faria ha costruito l'albero genealogico del virus. Il risultato ha determinato che tutti i genomi dell'HIV condividono un antenato comune risalente a pi\u00f9 di 100 anni fa.<a href=\"https:\/\/mindthegraph.com\/\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter wp-image-5732 size-medium\" src=\"https:\/\/blog.mindthegraph.com\/wp-content\/uploads\/2016\/06\/untitled-creation63724-1-300x120.png\" alt=\"Virus HIV\" width=\"300\" height=\"120\" srcset=\"https:\/\/mindthegraph.com\/blog\/wp-content\/uploads\/2016\/06\/untitled-creation63724-1-300x120.png 300w, https:\/\/mindthegraph.com\/blog\/wp-content\/uploads\/2016\/06\/untitled-creation63724-1-1024x410.png 1024w, https:\/\/mindthegraph.com\/blog\/wp-content\/uploads\/2016\/06\/untitled-creation63724-1.png 1500w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a>L'origine del virus HIV intorno al 1920 ha aiutato i ricercatori a risalire alla citt\u00e0 in cui il virus potrebbe essere comparso: Kinshasa, nella Repubblica Democratica del Congo. La storia ci dice che questa promettente citt\u00e0 \u00e8 cambiata con la costruzione di ferrovie e con i lavoratori del sesso - due forme di trasporto che il virus dell'HIV ha trovato per diffondersi.<\/p>\n<p>In origine, esistono due tipi di virus HIV: Il gruppo M dell'HIV-1 e il gruppo O dell'HIV-1. Il gruppo M dell'HIV-1 \u00e8 quello che si \u00e8 diffuso da Kinshasa nel mondo. Il gruppo O dell'HIV-1, invece, \u00e8 nato nelle vicinanze ma non si \u00e8 mai diffuso, rimanendo in Africa occidentale fino ai giorni nostri.<\/p>\n<p><a href=\"https:\/\/mindthegraph.com\/\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter wp-image-5937 size-full\" src=\"https:\/\/blog.mindthegraph.com\/wp-content\/uploads\/2016\/06\/output_vx7nah.gif\" alt=\"Virus HIV\" width=\"945\" height=\"708\" \/><\/a><\/p>\n<p>Faria ritiene che l'evoluzione di entrambi i gruppi possa aiutarci a capire come si sviluppa questa malattia. Si concentra sulle differenze tra i gruppi e su come queste possano determinare le fasi successive del virus.<\/p>\n<p>Scoprire il passato dell'HIV potrebbe essere la risposta per cambiare il futuro di questo virus.
