Hypertrophic differentiation occurs during in vitro chondrogenesis of mesenchymal stem cells (MSCs), decreasing the quality of the cartilage construct. Previously we identified WNT pathway antagonists Dickkopf 1 homolog (DKK1) and frizzled-related protein (FRZB) as key factors in blocking hypertrophic differentiation of human MSCs (hMSCs). In this study, we investigated the role of endogenously...
The important family of G protein-coupled receptors has so far not been targeted very successfully with conventional monoclonal antibodies. Here we report the isolation and characterization of functional VHH-based immunoglobulin single variable domains (or nanobodies) against the chemokine receptor CXCR4. Two highly selective monovalent nanobodies, 238D2 and 238D4, were obtained using a time-ef...
Chemical crop protection is widely used to control plant diseases. However, the adverse effects of pesticide use on human health and environment, resistance development and the impact of regulatory requirements on the crop protection market urges the agrochemical industry to explore innovative and alternative approaches. In that context, we demonstrate here the potential of camelid single domai...
Single-domain antibodies (sdAbs) found in camelids lack a light chain, and their antigen-binding site sits completely in the heavy-chain variable domain (VHH). Their simplicity, thermostability, and ease in expression have made VHHs highly attractive. Although this has been successfully exploited for macromolecular antigens, their application to the detection of small molecules is still limited...
با توجه به کاربردهای گسترده تشخیصی و درمانی آنتی بادیهای مونوکلونال، تولید آنها از منابع دائمی، ایمن و ارزان حائز اهمیت می باشد. از جمله، می توان به آنتی بادی مونوکلونال تک دومنی با منشأ شتری vhh اشاره نمود که به دلیل دارا بودن ویژگیهایی از جمله: تشابه بسیار با زنجیره سنگین آنتی بادیهای انسانی، حلالیت، تمایل و اتصال اختصاصی به آنتی ژن، بر دیگر انواع آنتی بادیها ترجیح داده می شود. در این تحقیق ا...
Immunotherapy using checkpoint-blocking antibodies against targets such as CTLA-4 and PD-1 can cure melanoma and non-small cell lung cancer in a subset of patients. The presence of CD8 T cells in the tumor correlates with improved survival. We show that immuno-positron emission tomography (immuno-PET) can visualize tumors by detecting infiltrating lymphocytes and, through longitudinal observati...
In vitro display technologies such as mRNA and cDNA display are powerful tools to create and select functional peptides. However, in some cases, efficiency of mRNA-protein fusion is very low, which results in decreased library size and lower chance of successful selection. In this study, to improve mRNA-protein fusion efficiency, we prepared an mRNA display library of a protein with random N- a...
