\ud83d\udd2c ER-100 Nedir?<\/strong><\/p>\n\n\n\n
ER-100, h\u00fccrelerin ya\u015flanma s\u00fcrecinde kaybettikleri fonksiyonlar\u0131 geri kazand\u0131rmay\u0131 hedefleyen k\u0131smi epigenetik reprogramlama yakla\u015f\u0131m\u0131n\u0131 kullan\u0131yor.
Bu y\u00f6ntemde:
H\u00fccre DNA\u2019s\u0131 de\u011fi\u015ftirilmez
Ancak genlerin \u00e7al\u0131\u015fma d\u00fczeni (epigenetik yap\u0131) gen\u00e7 h\u00fccrelere benzer bir duruma d\u00f6nd\u00fcr\u00fclmeye \u00e7al\u0131\u015f\u0131l\u0131r
Ama\u00e7, h\u00fccreleri tamamen k\u00f6k h\u00fccreye \u00e7evirmek de\u011fil, \u201cdaha gen\u00e7 bir i\u015flevsel seviyeye\u201d getirmektir
Bu teknoloji daha \u00f6nce fare ve primat deneylerinde test edilmi\u015fti. \u0130nsanlarda uygulanmas\u0131 ise ilk kez bu \u00e7al\u0131\u015fma ile m\u00fcmk\u00fcn oldu.<\/p>\n\n\n\n
Deneme do\u011frudan \u201ckozmetik gen\u00e7le\u015fme\u201d de\u011fil; ya\u015fa ba\u011fl\u0131 ciddi g\u00f6z hastal\u0131klar\u0131n\u0131 hedefliyor:
A\u00e7\u0131k a\u00e7\u0131l\u0131 glokom
Non-arteritik anterior iskemik optik n\u00f6ropati (NAION)
Bu hastal\u0131klarda optik sinir h\u00fccreleri hasar g\u00f6r\u00fcr ve mevcut tedaviler hasar\u0131 geri \u00e7eviremez. ER-100 ise h\u00fccre fonksiyonunu yeniden canland\u0131rmay\u0131 ama\u00e7l\u0131yor.
\ud83d\udcca Klinik \u00c7al\u0131\u015fma Hangi A\u015famada?
FDA, ER-100 i\u00e7in IND (Investigational New Drug) ba\u015fvurusunu onaylad\u0131.
Deneme \u015fu anda Faz 1 a\u015famas\u0131nda.
\u00d6ncelikli ama\u00e7: g\u00fcvenlik ve tolere edilebilirlik de\u011ferlendirmesi.

\u0130lk g\u00fcvenlik verilerinin y\u0131l sonuna kadar a\u00e7\u0131klanmas\u0131 bekleniyor.
Faz 1 a\u015famas\u0131nda genellikle:
Az say\u0131da hasta yer al\u0131r

\ud83e\uddec Neden Tarihi Bir Ad\u0131m?<\/strong>
Bu \u00e7al\u0131\u015fma, ya\u015flanmay\u0131 biyolojik d\u00fczeyde geri \u00e7evirme iddias\u0131n\u0131 insanlarda test eden ilk resmi FDA onayl\u0131 klinik giri\u015fimlerden biri olmas\u0131 nedeniyle dikkat \u00e7ekiyor.
Daha \u00f6nce benzer \u00e7al\u0131\u015fmalar:
Farelerde g\u00f6rme fonksiyonunu iyile\u015ftirmi\u015fti
Primat modellerinde h\u00fccresel ya\u015f g\u00f6stergelerinde gerileme g\u00f6stermi\u015fti

\u26a0\ufe0f Uzmanlar\u0131n Uyar\u0131s\u0131<\/strong>
Bilim insanlar\u0131 \u015fu noktaya dikkat \u00e7ekiyor:
Bu erken a\u015fama bir g\u00fcvenlik denemesi
Ba\u015far\u0131 garantisi yok
Uzun vadeli etkiler hen\u00fcz bilinmiyor
H\u00fccresel yeniden programlama teorik olarak t\u00fcm\u00f6r riskleri gibi ciddi sorular bar\u0131nd\u0131r\u0131yor<\/p>\n\n\n\n
\ud83d\udcc5 Bundan Sonra Ne Olacak?<\/strong>
E\u011fer Faz 1 g\u00fcvenli bulunursa:
Faz 2: Daha geni\u015f hasta grubunda etkinlik de\u011ferlendirmesi
Faz 3: B\u00fcy\u00fck \u00f6l\u00e7ekli kar\u015f\u0131la\u015ft\u0131rmal\u0131 klinik \u00e7al\u0131\u015fma
FDA onay\u0131 ve potansiyel ticarile\u015fme
Bu s\u00fcre\u00e7 genellikle 5\u20138 y\u0131l s\u00fcrebilir.<\/p>\n\n\n\n
ER-100, ya\u015flanmay\u0131 geri \u00e7evirme ara\u015ft\u0131rmalar\u0131nda insan a\u015famas\u0131na ge\u00e7ilmi\u015f ilk ciddi ad\u0131mlardan biri olarak g\u00f6r\u00fcl\u00fcyor.
Ancak \u015fu an i\u00e7in:
