AMINO ACID SEQUENCES TARGETING HUMAN CD4, CXCR4, CCR5, TLR4, ALPHAV INTEGRIN, BETA3- INTEGRIN, BETAL -INTEGRIN, HUMAN ALPHA2- INTEGRIN, CD81, SR-BI, CLAUDIN-I, CLAUDIN-6 AND CLAUDIN-9, RESPECTIVELY, AND NEUTRALIZING VIRAL ENTRY

摘要

The present invention relates to amino acid sequences that are directed against (as defined herein) human cellular receptors for viruses and/or bacteria such as e.g. Nanobodies specifically recognizing hCD4, hCXCR4, hCCR5. hTLR4, human alphaV integrin, human beta3 integrin, human betal integrin, human alpha2 integrin, hCD81, hSR-Bl, hClaudin-1, hClaudin-6 and hClaudin-9, as well as to compounds or constructs, and in particular proteins and polypeptides, that comprise or essentially consist of one or more such amino acid sequences. Said amino acid sequences may be used to prevent human cell entry of HIV, HCV, adenoviruses, hantavirus, herpesvirus, echo-virus 1 and others.
