Il sistema immunitario usa delle cellule staminali particolarmente efficienti per rifornire pi\u00f9 rapidamente l’organismo delle difese necessarie, le cosiddette cellule ‘natural killer’, a contrastare virus e altri agenti patogeni.
\nLo ha scoperto uno studio dell’Ospedale Pediatrico Bambino Ges\u00f9 e dell’Universit\u00e0 di Genova con la collaborazione di altri Centri italiani, finanziato anche da Airc, pubblicato sul Journal of Allergy and Clinical Immunology.<\/p>\n

Nella ricerca sono stati coinvolti pazienti pediatrici e adulti affetti da HIV, epatite C e infezione da citomegalovirus. Gli studi di laboratorio sul sangue dei pazienti investigati, scrive Ansa<\/a>, hanno portato alla scoperta di due nuovi tipi di staminali, individuate grazie a particolari marcatori della loro superficie cellulare.<\/p>\n

“Le cellule staminali identificate per la prima volta con la nostra ricerca sono state rintracciate in grandi quantit\u00e0 nel sangue di pazienti con infezioni virali. Rappresentano, quindi, una sorta di scorciatoia utilizzata dal sistema immunitario per generare rapidamente ‘natural killer’ quando c’\u00e8 bisogno di nuove armi contro i patogeni – commenta Lorenzo Moretta, responsabile dell’Area di Ricerca di Immunologia del Bambino Ges\u00f9 insieme ad Andrea De Maria del Dipartimento di Scienze della Salute dell’Universit\u00e0 di Genova -. Una volta isolate e coltivate in laboratorio, le nuove staminali si moltiplicano e, in circa 3 settimane, danno origine a cellule NK mature, dotate di una spiccata capacit\u00e0 di uccidere le cellule tumorali e pronte a combattere i virus, soprattutto il citomegalovirus”.<\/p>\n

Lo studio \u00e8 svolto insieme all’Ospedale Pediatrico Istituto Gaslini, all’Ospedale Sacro Cuore Don Calabria, all’Universit\u00e0 di Torino, all’Ospedale Sanremo e all’Ospedale Policlinico San Martino.<\/p>\n
