ProTGFB1-GARP complex-selective antibodies, polynucleotides capable of encoding the proTGFB1-GARP complex-selective antibodies or antigen-binding fragments, cells expressing proTGFB1-GARP complex-selective antibodies or antigen-binding fragments, as well as associated vectors and detectably labeled proTGFB1-GARP complex-selective antibodies or antigen-binding fragments may be used to enhance an immune response in a subject, for example, against a cancer.
