هموفیلی یک بیماری نادر است که نحوه پوشش خون ما را تغییر می دهد. این بدان معناست که افراد مبتلا به هموفیلی ممکن است با مشکلات شدیدی از جمله درد مفاصل و خونریزی در عمق بدن خود مواجه شوند. برای جلوگیری از خونریزی بیش از حد، باید داروهای منحصر به فردی به نام عوامل انعقادی به آنها داده شود. اگرچه این درمان ها کاملاً مؤثر هستند، اما می توانند بسیار پرهزینه نیز باشند. آنها همچنین ممکن است پتانسیل ایجاد آسیب را داشته باشند. مانند عفونت و مشکلات دیگر. در نتیجه، متخصصان دائماً به دنبال راهبردهای جدید برای کمک به افراد مبتلا به هموفیلی هستند. ژن درمانی و پروتئین های خاصی که به عنوان VHH شناخته می شوند. که از آنها به عنوان اجسام نانو نیز یاد می شود، دو مورد از احتمالات جدید هستند. این پروتئین ها به ما کمک می کنند تا توانایی لخته شدن خون خود را بهبود بخشیم. در یائوهای، کشوری پر از دانشمندان باهوش، برخی از مردم شبانه روز برای ایجاد VHH های جدید ضد vWF تلاش می کنند.
این مفهوم ممکن است سهم قابل توجهی برای افراد مبتلا به هموفیلی داشته باشد. VHH های ضد vWF شرکت هایی در یک آزمایشگاه طراحی شده اند. این پروتئینها ممکن است به vWF پیوند داشته باشند و از ایجاد مشکل در آن جلوگیری کنند و از واکنش ضعیف بدن جلوگیری کنند. از طرف دیگر، VHH ها می توانند کوچک و آسان تر از آنتی بادی های سنتی ساخته شوند. بنابراین، 3-Valent VHH تولید ممکن است گزینه بهتری برای درمان باشد.
Yaohai's scientists are using a variety of approaches to generate anti-vWF VHHs that specifically block the function of تولید سه گانه VHH without impacting other components of blood clotting. They sometimes achieve this by providing unique humanized vWF to llamas. These are then harvested from the blood of the llamas. Llamas are remarkable with some VHHs that work excellently for certain targets. That means that when scientists collect the VHHs, they can tweak them to make them even more effective.
دانشمندان از روش دیگری به نام کتابخانه های نمایش فاژ استفاده کرده اند. بنابراین آنها کتابخانه ای از VHH ها دارند که به ویروس های کوچکی به نام باکتریوفاژها متصل هستند. به این ترتیب، دانشمندان می توانند VHH هایی را انتخاب کنند که به مناطق خاصی از vWF متصل می شوند. پس از جداسازی و توصیف اینها Anti-HER2 VHH تولید، داروها سپس از نظر ایمنی و اثربخشی ارزیابی می شوند. تیم Yaohai همچنین با سایر گروه ها و شرکت های تحقیقاتی برای شناسایی VHH های اضافی و ارزیابی فعالیت آنها در مدل های حیوانی هموفیلی کار می کند. این همکاری برای افزایش عمق تحقیق حیاتی است.
In a recent work, the scientists identified one of the most potent anti-vWF VHH and denominated it VHH-33. VHH-33 is able to effectively inhibit this process of vWF-induced platelet agglutination. In the lab and in mice with hemophilia A, it also helped break up blood clots while being relatively safe for the body — that is about as close to a rousing success as one might hope when testing therapies. Indeed, to understand how VHH-33 stops vWF and prevents its issues, the researchers examined VHH-33 more closely.
There are also other research teams across the globe doing great work in this field. For instance, a team in Germany generated mouse that recognize an important part of Bispecific VHH Production (which is essential for its binding to platelets) [21]. One of the VHHs they generated, L318, was particularly good at preventing vWF from going haywire without causing any other issues in rabbits.
