Quand l\u2019immunit\u00e9 devient menace<\/strong><\/span><\/h1>\n

Et si le corps, au lieu de se prot\u00e9ger, apprenait \u00e0 se mettre en danger ?<\/p>\n

Avec L\u2019Anaphylaxie<\/em>, Charles Richet signe l\u2019un des textes les plus \u00e9tonnants de l\u2019histoire de la m\u00e9decine moderne. En 1902, il forge un mot nouveau pour d\u00e9signer un ph\u00e9nom\u00e8ne d\u00e9routant : une premi\u00e8re exposition \u00e0 une substance peut rendre l\u2019organisme non pas plus r\u00e9sistant, mais plus vuln\u00e9rable. Ce qui \u00e9tait tol\u00e9r\u00e9 hier peut devenir, demain, un poison foudroyant.<\/p>\n

\u00c0 rebours de l\u2019id\u00e9e simple d\u2019une immunit\u00e9 toujours protectrice, Richet r\u00e9v\u00e8le une v\u00e9rit\u00e9 plus inqui\u00e9tante : le vivant garde m\u00e9moire de ses rencontres. S\u00e9rums, toxines, aliments, infections, substances \u00e9trang\u00e8res \u2014 tout peut laisser dans le corps une trace silencieuse. Cette trace, lors d\u2019un second contact, peut d\u00e9clencher une r\u00e9action violente, parfois mortelle.<\/p>\n

La puissance de cet essai tient \u00e0 son originalit\u00e9 conceptuelle. Richet ne se contente pas de d\u00e9crire un accident biologique. Il d\u00e9couvre une m\u00e9moire du corps, qu\u2019il nomme \u00ab individualit\u00e9 humorale \u00bb. Chaque \u00eatre vivant devient ainsi le produit de son histoire chimique. Aucun organisme ne revient exactement \u00e0 son \u00e9tat ant\u00e9rieur apr\u00e8s une exposition d\u00e9cisive. Le corps se souvient, et cette m\u00e9moire peut sauver autant qu\u2019elle peut frapper.<\/p>\n

Texte fondateur de l\u2019immunologie et de l\u2019allergologie modernes, L\u2019Anaphylaxie<\/em> est aussi une r\u00e9flexion saisissante sur l\u2019identit\u00e9 biologique. Richet y montre que le vivant n\u2019est jamais neutre devant le monde : il re\u00e7oit, transforme, conserve, r\u00e9agit. Et parfois, dans l\u2019exc\u00e8s m\u00eame de sa d\u00e9fense, il se retourne contre lui-m\u00eame.<\/p>\n

Ce livre invite le lecteur \u00e0 d\u00e9couvrir une pens\u00e9e scientifique audacieuse, n\u00e9e du laboratoire, mais port\u00e9e par une intuition presque philosophique : nous ne sommes pas seulement ce que nous sommes ; nous sommes aussi ce que notre corps a rencontr\u00e9.<\/p>","protected":false},"excerpt":{"rendered":"
