1. A polypeptide construct comprising:
a first portion comprising the second constant domain (CH2) and/or third constant domain (CH3) of an antibody heavy chain, and
a second portion comprising at least two TGF-β superfamily receptor ectodomains (TβSR-ED) linked in tandem,
wherein the N-terminus of the second portion is linked to the C-terminus of the first portion,
wherein the at least two TβSR-EDs are TGF-β receptor II ectodomains (TβR-II-EDs), and
wherein the polypeptide construct has neutralization activity against TGF-β2.
