The present invention relates to amino acid sequences that block the interaction between (a target on) an antigen presenting cell (APC) and (a target on) a T-cell. More particularly, the present invention relates to amino acid sequences that are directed against (as defined herein) a target on an APC (also referred to herein as “APC target”) or a target on a T-cell (also referred to herein as “T-cell target”). The invention further relates to compounds or constructs, and in particular proteins and polypeptides, that comprise or essentially consist of one or more such amino acid sequences. |
