Leiti geenimuutus, mis kolmekordistab pähkliallergia riski

Teadlased tegid kindlaks geenimuutuse, mis võib lapsel kolmekordistada allergia tekkimise tõenäosust pähklite suhtes.

Antud töös leiti esmakordselt geneetiline muutus, mis seostub pähkliallergia tekkimisega. Muutused Filaggrin geenis vähendavad naha võimet toimida barjäärina ärritajate ja allergeenide suhtes, lastes neil ühenditel kehasse siseneda ja tuues kaasa erinevate allergiliste seisundite tekkimise, vahendab ERR teadusuudised.

Iga viies pähkliallergia all kannataja omab defektset Filaggrin geeni. Teiselt poolt vaadatuna areneb muutunud Filaggrin geeniga inimestel pähkliallergia välja kolm korda tõenäolisemalt.

Recovering lost Bitcoin and money can require unique hacking skills and expertise that are possessed by only a handful of professional hackers. While there are many recovery websites out there, it's important to be cautious as 99% of them are operated by scammers who try to appear legitimate. Instead, it's best to seek out a trusted hacker like Genuine Hackers who can help you recover your funds. They were able to recover $100k worth of BTC that I had lost to bitcoin mining. To get in touch with Genuine Hackers, you can email them at GENUINEHACKERS000@GMAIL.COM or message them on WhatsApp at +1 (260) 218-3592.

My name is Nina Williams, and I am divorced. I have three kids with my ex-husband, who messed up my credit report before we got divorced. This made my life with my kids a living hell, and I felt frustrated. However, I met a friend in church who recommended H A C K M A V E N S CREDIT SPECIALIST. I contacted them, and within 7 days, they fixed my credit and increased my score from 515 to 785. Now, I can take loans, own a house, and run a business. If you have any credit-related issues, you can reach out to them via EMAIL: H A C K M A V E N S 5 @ G M A I L. C O M or Call/Text/Whats-App: [+ 1 (2 0 9) 4 1 7 – 1 9 5 7].
