\n D\u00c9CRYPTAGE <\/strong>– Cet organe de l\u2019immunit\u00e9, tr\u00e8s actif pendant l\u2019enfance, s\u2019impose aujourd\u2019hui comme un acteur cl\u00e9 de notre sant\u00e9 m\u00eame \u00e0 l\u2019\u00e2ge adulte. Son \u00e9tat permettrait de pr\u00e9dire mortalit\u00e9, cancer et r\u00e9ponse \u00e0 certains traitements.<\/p>\n

Pendant des d\u00e9cennies,\u00a0le thymus<\/a>\u00a0a \u00e9t\u00e9 rel\u00e9gu\u00e9 au rang d\u2019acteur secondaire de l\u2019immunit\u00e9 adulte. Un organe tr\u00e8s actif dans l\u2019enfance, puis vou\u00e9 \u00e0 l\u2019oubli. Mais deux \u00e9tudes publi\u00e9es en mars dans la revue Nature bousculent cette certitude. Quel que soit votre \u00e2ge, un thymus en bonne sant\u00e9 serait associ\u00e9 \u00e0 une baisse de la mortalit\u00e9 toutes causes, un risque cardiovasculaire diminu\u00e9 et \u00e0 une incidence plus faible de\u00a0cancer<\/a>. Il am\u00e9liorerait \u00e9galement la r\u00e9ponse \u00e0 l\u2019immunoth\u00e9rapie<\/a>\u00a0en oncologie.<\/p>\n

Pour parvenir \u00e0 ces conclusions, les chercheurs de Harvard ont\u00a0entra\u00een\u00e9 un algorithme<\/a>\u00a0\u00e0 quantifier la \u00ab\u00a0sant\u00e9\u00a0\u00bb du thymus \u00e0 partir de scanners thoraciques de routine. Taille, forme, densit\u00e9… l\u2019IA calcule un score thymique confront\u00e9 aux donn\u00e9es de deux grandes cohortes.\u00a0Les r\u00e9sultats publi\u00e9s dans Nature<\/a> \u00a0parlent d\u2019eux-m\u00eames\u00a0: un score \u00e9lev\u00e9 est associ\u00e9 \u00e0 un risque de mortalit\u00e9 toutes causes inf\u00e9rieur de 50\u00a0%, un risque de mortalit\u00e9 cardiovasculaire r\u00e9duit de 63\u00a0% et un risque de cancer du poumon\u2026<\/p>\n
