Un dominio variable único de inmunoglobulina anti-TGFbetaRII que comprende una secuencia de aminoácidos como se indica en la SEQ. ID. nº 267 que tiene hasta 5 sustituciones moderadas de aminoácidos en donde dichas sustituciones moderadas de aminoácidos no están comprendidas en ninguna de las CDR y en donde dicho dominio variable único de inmunoglobulina anti-TGFbetaRII se une al TGFbetaRII humano con una constante de disociación (KD) del equilibrio de aproximadamente 10 pM o menos medida por resonancia de plasmón de superficie. The disclosure provides an anti-TGFbetaRII immunoglobulin single variable domain. Suitably, an anti-TGFbetaRII immunoglobulin single variable domain in accordance with the disclosure is one having an amino acid sequence as set forth in any one of SEQ ID NO:1-28 having up to 5 amino acid substitutions, deletions or additions. The disclosure further provides a polypeptide and pharmaceutical composition for treating a disease associated with TGFbeta signalling and suitably a disease selected from the group of: tissue fibrosis, such as pulmonary fibrosis, including idiopathic pulmonary fibrosis; liver fibrosis, including cirrhosis and chronic hepatitis; rheumatoid arthritis; ocular disorders; fibrosis of the skin, including keloid of skin; Dupuytren's Contracture; kidney fibrosis such as nephritis and nephrosclerosis; wound healing; scarring reduction; and a vascular condition, such as restenosis.
